The symbol used to show a protective earth terminal in the instrument is . Before operation, you should review the instrument and manual, including the red safety page, for safety markings and instructions. You must follow these to ensure safe operation and to maintain the instrument in safe condition. Some HP 8153A circuits are powered whenever the instrument is connected to the AC power source. To disconnect from the line power, disconnect the power cord either at the rear power-inlet or at the AC line-power source (receptacle). One of these must always be accessible. If the instrument is in a cabinet, it must be disconnected from the line power by the system's line-power switch. Warning To avoid hazardous electrical shock, do not perform electrical tests when there are signs of shipping damage to any portion of the outer enclosure (covers, panels, etc.). Line Power Requirements The HP 8153A can operate from any single-phase AC power source that supplies between 100V and 240V at a frequency in the range from 40 to 60Hz. The maximum power consumption is 55VA with all options installed. The fuse used by this instrument is T1A / 250V (slow) (HP Part No. 2110-0007). Changing the fuse should be carried out only by a quali ed electrician or by HP service personnel as it is necessary to open the instrument. Line Power Cable In accordance with international safety standards, this instrument has a three-wire power cable. When connected to an appropriate AC power receptacle, this cable earths the instrument cabinet. The type of power cable shipped with each instrument depends on the country of destination. Refer to Figure 0-1 for the part numbers of the power cables available. iii Figure 0-1. Line Power Cables - Plug Identi cation To avoid the possibility of injury or death, you must Warning observe the following precautions before switching on the instrument. If this instrument is to be energized via an autotransformer for voltage reduction, ensure that the Common terminal connects to the earthed pole of the power source. Insert the power cable plug only into a socket outlet provided with a protective earth contact. Do not negate this protective action by the using an extension cord without a protective conductor. Before switching on the instrument, the protective earth terminal of the instrument must be connected to a protective conductor. You can do this by using the power cord supplied with the instrument. It is prohibited to interrupt the protective earth connection intentionally. iv The following work should be carried out by a quali ed electrician, and all local electrical codes must be strictly observed. If the plug on the cable does not t the power outlet, or if the cable is to be attached to a terminal block, cut the cable at the plug end and rewire it. The color coding used in the cable depends on the cable supplied. If you are connecting a new plug, it should meet the local safety requirements and include the following features: Adequate load-carrying capacity (see table of speci cations). Ground connection. Cable clamp. Operating Environment Warning The HP 8153A is not designed for outdoor use. To prevent potential re or shock hazard, do not expose the HP 8153A to rain or other excessive moisture.

The HP 8153A System The central element of the system is the HP 8153A mainframe. You customize the instrument using plug-in modules and a changeable ber-connector interfaces. Figure 1-1. The HP 8153A System Getting Started 1-1 1 A Quick Overview The Keyboard Most of the keys have two functions, depending on the selected mode. Di erent colors, or whether the legend is on the key or above it, show these di erent functions. Figure 1-2. The HP 8153A Keyboard The 4Chan5 key, the 4Mode5 key, and the modify keys always have the same function. 4Chan5 Select the channel. The other keys act only on the selected channel. Channel A corresponds to the module in the left slot. Channel B corresponds to the module in the right slot. 4Mode5 Switch between Measure and Menu Mode. Modify 4(5, 4)5 Select the digit or character to edit. Keys Edit the selected digit or character, or the parameter. 4+5, 4*5 Measure Mode Measure mode is the mode selected automatically when you switch on the instrument. In this mode you can set up and make simple measurements. In measure mode, the black writing on the key shows its function. 4Param5 Select the measurement-parameter that you want to view or edit. 1-2 Getting Started 1 !Ref5 Measure and record the input power-level for use as a reference. 4dB5 Display the input power-level relative to a reference. 4dBm/W5 Switch between dBm and Watt units. 4Zero5 Measure the electrical noise in the instrument, and compensate for it. 4N Dig5 Select the number of decimal places shown in the result. Range Keys 4Auto5 Start or stop automatic ranging. 4Up5 Select the next higher measuring range. Select the next lower measuring range. 4Down5 4Disp Menu Mode In this mode there are pre-programmed routines to perform some common, but more complicated, measurements. In menu mode, the blue writing above the key shows the function of the key. There are some keys whose operation is common to all of the tasks you do in menu mode. 4Edit5 gives you access to the parameters for editing. 4Prev5 and 4Next5 step through the items in a menu. For example, these can be di erent types of Record applications, or the di erent parameters for the system con guration. 4Exec5 to execute an application, or to nish editing a change of a system parameter. 4Pause5 to pause the running application or to continue a paused application. 4System5 Select system-parameters. This allows you to view or edit the con guration of the instrument. 4Loss5 Select the Loss application. A loss measurement tells you how much of your optical signal you lose by passing it through a device. Loss is calculated by the following formula: Loss = 10log( Pout )dB Pin To measure loss you need both quantities, Pin and Pout . The application records Pin when you start the application. The instrument expresses all the following results relative to this. These results are loss results. Getting Started 1-3 1 4Record5 4More5 Select from the Stability, Logging, Manual Logging, Plot or Print applications. Stability takes samples at evenly spaced intervals for a speci ed period. The parameters for this application are T_TOTAL Which sets the total time over which the measurements are to be made. AUTODUMP Which sets whether the results are output to a printer or plotter when the application nishes. Logging takes a speci ed number of samples one immediately after the other. That is, as soon as the rst sample has ended, the second starts. The parameters for this application are SAMPLES Which sets the number of samples to be taken. AUTODUMP Which sets whether the results are output to a printer or plotter when the application nishes. START Which sets whether the application starts immediately, or only after the power goes above, or below, a speci ed threshold level. THRESHLD Which sets the threshold level to be passed before the application begins. Manual Logging takes a sample each time the user presses the 4Exec5 key. In addition, the plot and print applications allow you to make a graphics plot, or a printout from the samples of your record application. The parameters for the plot and print applications are AUTOSCAL Which sets whether the axes are scaled automatically or not. Y_MIN Which sets the minimum value for the y-axis. Y_MAX Which sets the maximum value for the y-axis. COMMENT Which allows you to add your own text to the printout or plot. Select from the other applications. As standard, the instrument has Show and Alignment applications. 1-4 Getting Started 1 The Show application lets you look at the sample values from the most recent Stability, Logging, or Manual Logging application. Some simple statistics for the results are also given. The Alignment application gives you visual, and audible feedback of the input power, to help you align two components for the maximum transfer of optical power. The parameters for this application are TYPE Which sets whether the maximum transferred power is determined automatically by the instrument, or set manually by the user. DELTA Which sets the size of the change in transferred power indicated on the display, or by the tone. MAXPOWER Which sets expected, or required, maximum transferred power. The 4Pause5 key switches on and o the tone. Getting Started 1-5 1 The Display The display shows the status and the readings. Figure 1-3. The HP 8153A Display Table 1-1.

This ends the sample session. 1-14 Getting Started 2 Measure Mode The default mode at switch-on is Measure Mode. When the instrument is in measure mode, the mode-indicator shows MEAS. In measure mode, the function of key is shown by the black legend on the key. The Chan Key 4Chan5 selects the channel. This can be A or B. The channel- indicator, at the top of the display, shows the selected channel. Note Functions in Measure mode apply only to the selected channel. When the instrument is under remote operation, this key acts as 4Local5. That is, it returns the instrument to local operation (unless Local Lockout is active). The Mode Key changes the operating mode. If you press this key in measure mode, it changes the instrument into menu mode (the next chapter gives a description of menu mode). 4Mode5 Note The commands described in this chapter can only be used when the instrument is in Measure mode. Local Control - Measure Mode 2-1 2 2 The Param Key Use 4Param5 to select a measurement-parameters for editing. The parameterindicator shows the selected parameter, the character eld shows the value of the parameter. You can select the next parameter by pressing 4Param5 again. When the hardware does not use a particular parameter, you cannot select it. When you have selected a parameter, you can edit it using the Modify keys (described later in this chapter). Some parameters are set by the instrument, these cannot be edited. The Applications in Menu mode also use the parameters set in Measure mode. Entry Status When you select a parameter, the editable part blinks. The editable part can be one digit or character, or the whole parameter. You can only edit a parameter, or a part of a parameter, while it is blinking. If you do not press any more keys within 10 seconds, the blinking stops and you are prevented from editing the value. You can enable editing again if you press any of the Modify keys. Note The instrument holds the parameter information in memory until you edit it. Switching the instrument o does not a ect the parameters. Default Values If you hold down 4Param5 for 2 seconds or longer, the parameter is set to its default value. Parameter List The parameters and their speci cations are as follows: This is the wavelength value. Sometimes, you can set the wavelength to any value within limits set by the module (for example, for a power sensor). For other modules, you can choose one wavelength from two possibilities (for 2-2 Local Control - Measure Mode example, multi-wavelength sources). In other cases, the module sets this value and you can display the value but you cannot edit it. Display Format nnnn.n nm Limits Depends on the module used. Resolution 0.1nm Default Depends on the module used. CAL This is a calibration o set that you can enter to compensate for external optical circuitry. This value is automatically subtracted from the input signal. Pmeasured (dBm) = Pinput (dBm) 0 CAL(dB ) Where, Pmeasured is the adjusted value of the signal read, Pinput is the input signal level, and CAL is the calibration o set. Display Format 6nnn.nnn dB Limits -200.000dB nnn.nnn +200.000dB Resolution .001dB Default 0.000dB When the calibration factor is not set to zero, the CAL parameter- indicator stays on at half brightness. T This is the length of time over which a signal is averaged. Longer averaging times increase the accuracy and improve the noise rejection of the measurement. Longer averaging times also decrease sensitivity and increase the length of time between updates of the results on the display. For averaging times of 1 second or less, a new measurement is shown on the display at the end of each averaging time. This is drawn in Figure 2-1. A new measurement is shown on the display at each x. Local Control - Measure Mode 2-3 2 2 Figure 2-1. Measurements with TAverage 1 second For averaging times of more than 1 second, the x value is given by the formula 1 0 Tsample Tsample xnew = xold + Sample Tavg Tavg Where xnew is the new, displayed result, xold is the previously displayed result, Sample is the value read by the hardware, Tavg is the averaging time (as set by the user), and Tsample is the time taken, by the hardware, to make a reading. If the measurement conditions are changed (for example, by a range change in autoranging) xold is reset, and the averaging starts again. This is why the display update seems faster in autoranging. Display Format nnn ms, s, min Values 20, 50, 100, 200, 500ms, 1, 2, 5, 10, 20, 30s, 1, 2, 5, 10, 15, 20, 30, 60min Default 200ms Figure 2-2. Editing the Averaging Time Parameter 2-4 Local Control - Measure Mode REF dB results are shown relative to a reference-level. This parameter sets the reference-level. You can choose the units for the reference using 4dBm W5. Setting, or changing, the reference only a ects results that are displayed in dB. Pdisplay (dB ) = Pmeasured 0 REF Where, Pdisplay is the displayed, relative power, Pmeasured is the absolute power-level (see \CAL"), and REF is the reference. Logarithmic Units Display Format 6nnn.nnn dBm Limits -200.000dBm nnn.nnn +200.000dBm Resolution Default 0.001dBm 0.000dBm Display Format Limits Resolution Default 5 digits pW, nW, W, mW. 0.001pW n 9999.9mW see Table 2-1 1000.0W Linear Units Local Control - Measure Mode 2-5 2 Table 2-1.

This parameter sets the attenuation of an output. Poutput = Psource 0 AT T (dB ) Where, Poutput is the power-level at the output of the module, Psource is the power-level at the output of the source, and ATT is the attenuation parameter. Display Format Limits Resolution Default 6n.n dB 0.0dB n.n 6.0dB 0.1dB 0.0dB 2-6 Local Control - Measure Mode AUX The output amplitude of a source can be modulated by a square wave. This parameter sets the frequency of the modulation. The modulation can be one of CW (continuous wave, that is no modulation), 270Hz, 1kHz, or 2kHz. Values CW, 270Hz, 1, 2kHz Default CW The Disp!Ref Key Pressing this key takes the input power-level and stores it as the reference. Setting, or changing, the reference in this way only a ects results displayed in dB. If the display is in dBm or Watts, the measured power-level is stored as the reference, that is REF = Pmeasured Where, REF is the reference, and Pmeasured is the absolute power-level (see \CAL"). If the display is in dB, this value is converted to dBm or Watts before being stored as a reference, that is REFnew = Pdisplay (dB ) + REFold Where, REFnew is the reference after the key press, Pdisplay is the displayed, relative power, and REFold is the reference before the key press. Local Control - Measure Mode 2-7 2 2 The dB Key This key switches the display to show results in dB. Results in dB are always given with respect to another power-level. This can be a stored reference, or it can be a second power-level. Using 4dB5 with a Two Sensor Instrument For an instrument with two sensors, the dB result can be with respect to the reference stored for the channel, or it can be with respect to the power-level of the other channel. If the result is in dB with respect to the power-level of the other channel, 4dB5 changes the result to dB with respect to the stored reference. The reference-indicator shows A/REF or B/REF. To see the reference , use 4Param5. To set the reference you use 4Param5 or 4Disp!Ref5. Pdisplay (dB ) = Pmeasured 0 REF Where, Pdisplay is the displayed, relative power, Pmeasured is the absolute power-level (see \CAL"), and REF is the reference. If the result is in dB with respect to the reference, 4dB5 changes the result to dB with respect to the power-level in the other channel. The reference-indicator shows A/B or B/A. When the result is with respect to the power-level in the other channel, the stored reference is also used in the calculation of the displayed result. Pdisplay (dB ) = Pmeasured1st Chan 0 Pmeasured2nd Chan 0 REF Where, Pdisplay is the displayed, relative power, Pmeasured is the absolute power-level (see \CAL"), and REF is the reference. If the result is in dBm or Watts, 4dB5 changes the result to dB. 2-8 Local Control - Measure Mode Using 4dB5 with a One Sensor Instrument changes the display to show the result as a relative value with respect to the stored reference. The reference-indicator shows A/REF or B/REF. To see the reference, use 4Param5. To set the reference, use 4Param5 or 4Disp!Ref5. 4dB5 Pdisplay (dB ) = Pmeasured 0 REF Where, Pdisplay is the displayed, relative power, Pmeasured is the absolute power-level (see \CAL"), and REF is the reference. The dBm/W Key This key changes the display to show results in dBm or in Watts. If the results are in dB, 4dBm W5 changes the display to showing the result as dBm or Watts. If the results are in dBm, 4dBm W5 changes the display to showing the results in Watts. If the results are in Watts, 4dBm W5 changes the display to showing the result in dBm. The Zero Key The 4Zero5 works with sensor modules. The function of 4Zero5 is to remove any electrical o set in the sensor circuitry. The instrument measures by converting optical power to electrical power, and then measuring the electrical power. An electrical o set is power that is always present, even if there is no light at the input. If this o set is not removed, it will a ect the results. 4Zero5 measures the electrical power when there is no light at the input. The instrument uses this value to remove the o set from all further incoming signals. Local Control - Measure Mode 2-9 2 2 Note The environmental conditions and the temperature of the instrument a ect the electrical o set. For the best results you must: Allow the instrument time to acclimatize (c.24 hours). Allow the instrument time to warm up (c.20 minutes). Make sure that the optical input is not receiving any light. If you are using multi-mode cable you must disconnect the cable and cover the input to the sensor to perform a zero. It is a good practice to zero the instrument before making any important measurements. The zero operation is performed just for the selected channel. The instrument automatically repeats the zero operation for each measurement range. Figure 2-3. The Display while Channel A is Being Zeroed If there is light at the sensor input during a zero operation, the instrument shows the message ZERO ERR. If you cannot remove the light, but you still want to use the instrument, you can abort the zero operation by pressing any key. 2-10 Local Control - Measure Mode The N Dig Key 2 This key selects the number of digits shown after the decimal point in the result. When you use 4N Dig5 rst, it reduces the number of digits shown. After the number of digits has been reduced to 1, 4N Dig5 increases the number of digits shown. The maximum number of digits after the decimal point is 3. The Range Keys The range keys select the range of the units for the result. The table below gives the possible ranges for results. The available ranges depend on the module used. Local Control - Measure Mode 2-11 2 Table 2-2. Power Ranges Range Upper Linear Power Limit +30dBm +20dBm +10dBm 0dBm -10dBm -20dBm -30dBm -40dBm -50dBm -60dBm -70dBm -80dBm -90dBm -100dBm -110dBm 1999.9mW 199.99mW 19.999mW 1999.9W 199.99W 19.999W 1999.9nW 199.99nW 19.999nW 1999.9pW 199.99pW 19.999pW 1.999pW 0.199pW 0.019pW The range the instrument is using shows on the display while you press a range keys. But, note that pressing a Range key alters the range used. Pressing 4Auto5 stops or starts the automatic ranging. Pressing 4Up5 or 4Down5 selects the next range before showing it. The bar graph below the result shows the result graphically. The left end of the bar is 0% of the selected range, the right end of the bar is 100% of the selected range. 2-12 Local Control - Measure Mode The Auto Key enables or disables automatic ranging for the result. Automatic ranging ensures that the result has a displayed value between 9% and 100% of full scale. While you have automatic ranging enabled, the operation-indicator shows AUTO in the middle of the display. The default state is for automatic ranging to be enabled. 4Auto5 The Up Key This key selects the next higher range. If automatic ranging was in operation, this key disables it. Example If the instrument is currently in the range 2.000 to 19.999W, pressing 4Up5 takes it to the 20.00 to 199.99W range. The Down Key This key selects the next lower range. If automatic ranging was in operation, this key disables it. Example If the instrument is currently in the -20dBm range, pressing 4Down5 takes it to the -30dBm range. The Analog Output The analog output is the BNC connector on the front of the sensor module. It outputs a voltage directly proportional to the strength of the optical signal at the optical input, in the current range. The analog signal is always in the range 0 to 2V, 2V corresponding to a full power input signal in the current range, 0V corresponding to no input signal. If the range changes, for example, during autoranging, the level to which 2V corresponds changes. Therefore it is recommended, if you want to use the analog output, disable autoranging and select the best range for the application with 4Up5 or 4Down5. Possible applications for the analog output, would be to close the feedback loop controlling the current supplied to a laser; or to monitor optical power on an oscilloscope (the analog signal reacts instantaneously to the input signal, whereas the power shown on the display is subject to averaging). Local Control - Measure Mode 2-13 2 2 The Modify Keys You use these keys to edit parameters. For the purposes of editing, there are two types of parameter. One type is the parameter that can have one of several, separate values, these are discrete valued parameters. The second type is the parameter that can have any value between certain limits, these are continuous valued parameters. Editing Discrete Valued Parameters When selecting one of several discrete values, the 4*5 selects the next highest value and the 4+5 selects the next lowest value. Example The averaging time can have only particular values. If you are editing this parameter and it is currently 200ms, pressing 4*5 changes the value to 500ms. If you are editing this parameter and it is currently 200ms, pressing 4+5 changes the value to 100ms. 4)5 and 4(5 have no e ect in the editing of discrete valued parameters. Editing Continuous Valued Parameters Where a value is being set from between certain limits, you can edit each character individually. The 4(5 changes the editable character to the next one on the left. The 4)5 changes the editable character to the next one on the right. The editable characters include each digit of numeric parameters, the decimal point (see below), and characters in messages. When a character is selected for editing it blinks. Pressing 4+5 decrements the editable character. The 4*5 increments the editable character. Editing Units To edit the magnitude of Watt values, select the decimal point as the editable character. Use the 4+5 to move the decimal point to the left, use 4*5 to move the decimal point to the right. When the decimal point reaches its rightmost or leftmost position, pressing the key again changes the multiplier of the units. 2-14 Local Control - Measure Mode Example If you are editing a reference, and the value is 234.5W, with the eld of edit at the decimal point, pressing 4+5 changes the value to 2.345nW. Similarly, if you are editing a reference, and the value is 2.345W, with the eld of edit at the decimal point, pressing 4*5 changes the value to 234.5mW. Local Control - Measure Mode 2-15 2 3 Menu Mode 3 In menu mode the instrument o ers several advanced test applications. When the instrument is in this mode, the mode-indicator shows MENU. In this mode the blue legends, above the keys, show the commands available to the user. The Chan Key 4Chan5 selects the channel. This can be A or B. The channel- indicator, at the top of the display, shows the selected channel. Note Functions in the Menu mode apply only to the selected channel. When the instrument is under remote control, this key acts as 4Local5. That is, it returns the instrument to local control (unless Local Lockout is active). The Mode Key changes the operating mode. If you press this key in menu mode, it changes the instrument into measure mode (the previous chapter gives a description of measure mode). 4Mode5 Note The commands described in this chapter can only be used when the instrument is in Menu mode. Local Control - Menu Mode 3-1 The System Key changes the instrument to system mode (the next chapter gives a description of system mode). 4System5 3 The Modify Keys The section \The Modify Keys" in Chapter 2, gives a description of how to use the Modify keys. The Loss Key starts the loss application. You need both a source and a sensor module to run this application. A loss measurement tells you how much of your optical signal you lose by passing it through a device. You calculate loss by the following formula: 4Loss5 Loss = 10log( Pout )dB Pin To measure loss you need both quantities, Pin and Pout . The application measures Pin when you start it running. Once you have taken a reference, the instrument expresses all the following results relative to this. These results are loss results. Preparation You need both a source and a sensor module for the Loss application. Before you start the Loss application, make sure that you have set all the measurement-parameters that you use. It is most important to make sure that you have set T for the sensor and for the source. If you are already in Menu mode, you have to return to Measure mode to set these parameters. 3-2 Local Control - Menu Mode Running the Loss Application After pressing 4Loss5, the instrument checks to see if both a source and sensor module are present. If one or both are missing the character eld shows the message CONFIG ?. The instrument does not enter the loss application. If both modules are present: The sensor wavelength is automatically set to the wavelength of the source. (When you stop the application running, the parameters for the sensor are automatically reset to the values in use before you started the application.) The operation-indicator shows APPL, this stays lit while the instrument is in the loss application. The instrument shows LOSS in the character eld. The instrument reads the reference level when you start the application running. To read the input signal and use it as the reference, do the following: 1. Make sure that the device under test is not in the system. 2. Make sure that the source is not active. The source is active whenever the green LED on its front panel lights. 3. Connect the source to the input of the system without the device under test. 4. Connect the output of the system to the sensor. Figure 3-1. Measuring the Reference for the Loss Application 5. Press 4Exec5. The instrument takes the reference and then runs the application. While the application is running, the RUN operation-indicator lights. Local Control - Menu Mode 3-3 3 3 Warning Do not look into the end of an optical cable attached to a laser output when the device is operational. Note Do not disconnect the ber from the source when making a loss measurement. A small change in the coupling at the source can introduce large errors into your measurement. Once you have taken the reference, you can place the device under test into the system. Figure 3-2. Measuring the Loss of a Device Under Test (DUT) Do not stop and restart the application as you insert and change devices under test. Every time you start the application, the instrument takes a new reference. You can switch the source o and on without disturbing the reference value. Do this to avoid exposure to laser radiation when you are changing the device under test. While the application is running, the result eld shows the loss, in dB, and the character eld shows the reference, in dBm. 1 indicates the result eld and 2 indicates the character eld in Figure 3-3. If you are using both wavelengths of a dual wavelength source, the loss and reference for both wavelengths are displayed. The loss and reference for the lower wavelength is shown on the left. The loss and reference for the higher wavelength is shown on the right. 3-4 Local Control - Menu Mode 3 Figure 3-3. The Loss Result 4Exec5 stops the application running. The Record Key starts the record applications. Record applications allow you to take a number of samples in succession. There are three types of record application. Stability takes samples at evenly spaced intervals over a speci ed period. Logging takes a speci ed number of samples one immediately after the other. That is, as soon as the rst sample has ended, the second starts. Manual Logging takes a sample each time the user presses the 4Exec5 key. In addition, there are plot and print applications that allow you to make a graphics plot, or a printout of the samples of your record application. The nal application on the Record key is the MinMax application, which displays minimum measured value and the di erence between this minimum and the maximum measured value, for a changing power level. 4Record5 Local Control - Menu Mode 3-5 Preparation You need a sensor module to perform any of the record applications. For the stability, or either of the logging applications, the only hardware setup you need is to have the device under test connected to the sensor. 3 Figure 3-4. Setup for a Record Application To make a plot of the samples you need a HPGL plotter. To get a printout of the samples you need a Thinkjet printer. If you are using a plotter or a printer, it must be attached as the only device to the HP-IB connector on the back of the instrument. The device address of the plotter must be set to 5. The device address of the printer must be set to 1. To output to a printer or plotter, the instrument HPIB State must be set to Talk Only (for instructions on how to do this see \MODE" in Chapter 4). With Firmware revisions 1.7 and greater, to output to a printer or plotter, the instrument HPIB State must be set to Talk Listen (the default condition). For information on setting the HPIB Status, see \MODE" in Chapter 4. Note To nd the rmware revision, switch o the instrument, and then hold any key while the instrument is powering up. The rmware revision is shown at the bottom right of the display. Switch o the instrument and power it up again for normal operation. Before you start a record application, make sure that you have set all the measurement-parameters that you use. It is most important to make sure that 3-6 Local Control - Menu Mode you have set T and for the sensor. If you are already in Menu mode, you have to return to Measure mode to set these parameters. After pressing 4Record5, you choose an application using 4Record5, 4Next5 or 4Prev5. 4Record5 and 4Next5 choose the next of the record applications. 4Prev5 chooses the previous of the record applications. While you are in the record applications the APPL operation-indicator lights. The application is displayed in the character eld of the selected channel. The Stability Application In the Stability application the instrument makes a number of evenly spaced samples over a period speci ed by the user. The application rst takes consecutive samples of the power from the device under test (that is, the next sample begins as soon as the previous one has nished). Some of this data is then discarded so that the samples are evenly spaced over the whole of the speci ed period. The maximum number of samples is 500. Example Tavg is set to 1s (Tavg is T set in Measure mode). The user sets the total time for the stability application to 8 minutes and 22 seconds. This is a total time of 502 seconds. The instrument takes 502 samples, but discards every second sample so that at the end, there are 251 evenly spaced samples. When you select the Stability application the character eld shows STABILTY. Figure 3-5. Selecting an Application : Stability Local Control - Menu Mode 3-7 3 3 This application has two parameters. T_TOTAL sets the total time for Stability application. AUTODUMP enables or disables the automatic plotting or printing of the samples when the application nishes. All the other parameters (Wavelength, Tavg , etc.) use the values given to them in measure mode. Press 4Edit5 to look at, or edit the parameters. After pressing 4Edit5, you can select parameters using 4Next5 and 4Prev5. While you are editing a parameter, the EDIT operation-indicator lights. T TOTAL When you select this parameter, the left side character eld shows the message T_TOTAL. The right side character eld shows the value for the total time. You edit the time using the Modify keys. The lower limit for the time is 1 second. The higher limit for the total time is 99 hours, 59 minutes and 59 seconds. The displayed value is always the setting for the total time. Due to the way the measurements are taken, you may nd that the application runs for a little longer than T_TOTAL. The di erence of the actual total time from T_TOTAL depends on a number of factors including the system con guration. The worst case timing di erence is 30s/h. You can press 4Edit5 if you have nished editing, or you can press 4Next5 or 4Prev5 to edit the other parameter. AUTODUMP When you select this parameter, the left side character eld shows the message AUTODUMP. The right side character eld shows whether the automatic dump has been enabled. The dump can be a plot of the samples or a printout of the samples. If the automatic dump is enabled the dump is made after the Stability application has taken the last sample. Note Other applications also use the same AUTODUMP parameter. Changing this parameter in the Logging application a ects the Stability application. The Plot application sets the parameters for an automatic plot. The Print application sets the parameters for an automatic print. These applications are described later in this chapter. You should not enable automatic dumping to a printer or plotter if there is a logging or stability application running in the other channel. The automatic dump is given priority, and 3-8 Local Control - Menu Mode the application in the other channel will be stopped for the duration of the print or plot. In the case of a logging application, the linearity of the timing information is a ected. In the case of a stability application, no new data is recorded while the dump is being made. You edit the dump enable using the Modify keys. It can have the value OFF, to disable both the automatic plot and the automatic print, PLOTTER to enable the plot, or PRINTER, to enable the print. The displayed value is always the setting for the dump. You can press 4Edit5 if you have nished editing, or you can press 4Next5 or 4Prev5 to edit the other parameter. Running the Stability Application To run the application, press 4Exec5. You cannot run the application if you are editing parameters. While the application is running, the RUN operation-indicator lights. While the application is running, the result eld shows the sample, and the character eld shows the time remaining until the application nishes. After all the samples have been taken, the RUN operation-indicator switches o . 4Pause5 suspends the running of the application. You can restart it by pressing 4Pause5 a second time. When you have pressed pause, you can look at the parameters set for the application in the Measure mode. You select parameters with 4Next5 and 4Prev5. 4Exec5 stops the application running. Local Control - Menu Mode 3-9 3 The Logging Application 3 In the Logging application the instrument makes a number of consecutive samples. The user speci es the number of samples. Consecutive samples are samples where one begins as soon as the previous one has nished. When you select the Logging application the character eld shows LOGGING. This application has several parameters. SAMPLES sets the number of samples that are to be taken. AUTODUMP enables or disables the automatic plotting or printing of the samples when the application nishes. START determines the conditions that have to be met before the application starts taking samples. THRESHLD sets the threshold power that must be crossed before the application starts taking samples. All the other parameters (Wavelength, Tavg , etc.) use the values given to them in measure mode. Press 4Edit5 to look at, or edit the parameters. After pressing 4Edit5, you can select parameters using 4Next5 and 4Prev5. While you are editing a parameter, the EDIT operation-indicator lights. The total time for the logging application consists of the averaging time and the time to process the sample. That is, a sample is only taken after the previous sample has been taken and processed. The processing time depends on a number of factors including the system con guration. If any applications or measurements are running in the other channel, the processing time between samples may vary. On printer or plotter outputs, the total time given for the logging application includes both the averaging and the processing time. SAMPLES When you select this parameter, the left side character eld shows the message SAMPLES. The right side character eld shows the number of samples to be taken. 3-10 Local Control - Menu Mode 3 Figure 3-6. Editing an Application Parameter : Samples You edit the number of samples using the Modify keys. The lower limit is 2. The higher limit is 500. The displayed value is always the setting for the number of samples. You can press 4Edit5 if you have nished editing, or you can press 4Next5 or 4Prev5 to edit the other parameters. AUTODUMP When you select this parameter, the left side character eld shows the message AUTODUMP. The right side character eld shows whether the automatic dump has been enabled. The dump can be a graphic plot of the samples or a printout of the samples. If the automatic dump is enabled the dump is made after the Stability application has taken the last sample. Note Other applications also use the AUTODUMP parameter. Changing this parameter in the Logging application a ects the Stability application. The Plot application sets the parameters for an automatic plot. The Print application sets parameters for an automatic print. These applications are described later in this chapter. You should not enable automatic dumping to a printer or plotter if there is a logging or stability application running in the other channel. The automatic dump is given priority, and the application in the other channel will be stopped for the duration of the print or plot. Local Control - Menu Mode 3-11 In the case of a logging application, the linearity of the timing information is a ected. In the case of a stability application, no new data is recorded while the dump is being made. 3 You edit the dump enable using the Modify keys. It can have the values OFF, to disable both the automatic plot and the automatic print, PLOTTER to enable the plot, or PRINTER, to enable the print. The displayed value is always the setting for the dump. You can press 4Edit5 if you have nished editing, or you can press 4Next5 or 4Prev5 to edit the other parameter. START When you select this parameter, the left side character eld shows the message START. The right side character eld shows which of the start conditions has been enabled. The application can be started immediately when you press 4Exec5, or it can be started when the input power-level is above or below a certain threshold. You edit the start condition using the Modify keys. It can have the values IMMEDIAT, to start the application when you press 4Exec5, ABOVE to start the application when the input power-level is above a certain threshold, or BELOW, to start the application when the input power-level is below a certain threshold. The displayed value is always the setting for the start condition. You can press 4Edit5 if you have nished editing, or you can press 4Next5 or 4Prev5 to edit the other parameter. THRESHLD You can only select this parameter when START is set to ABOVE or BELOW. When you select this parameter, the left side character eld shows the message THRESHLD. The right side character eld shows the threshold that has to be crossed before the application starts taking samples. You edit the threshold using the Modify keys. The lower limit is -400.00dBm. The higher limit is 400.00dBm. The displayed value is always the setting for the threshold. You can press 4Edit5 if you have nished editing, or you can press 4Next5 or 4Prev5 to edit the other parameters. 3-12 Local Control - Menu Mode Running the Logging Application To run the application, press 4Exec5. You cannot run the application if you are editing parameters. While the application is running, the RUN operation-indicator lights. While the application is running, the result eld shows the sample, and the character eld shows the number of samples that have been taken. After all the samples have been taken, the RUN operation- indicator switches o . 4Pause5 suspends the running of the application. You can restart it by pressing 4Pause5 a second time. When you have pressed pause, you can look at the parameters set for the application in the Measure mode. You select parameters with 4Next5 and 4Prev5. 4Exec5 stops the application running. The Manual Logging Application In the Manual Logging application the instrument takes a sample every time the user presses 4Exec5. When you select the Logging application the character eld shows MAN LOGG. Press 4Edit5 to look at the existing samples, or to take a sample again. After pressing 4Edit5 you can select a sample using the Modify keys. While you are editing samples, the EDIT operation- indicator lights. To take a sample again, press 4Exec5, the input power-level replaces the power-level logged for the chosen sample. Press 4Edit5 if you have nished editing. Running the Manual Logging Application While the application is running, the result eld shows the input power-level, and the character eld shows the number of samples taken. To take a sample, press 4Exec5. When you press 4Exec5 the result is stored as the next sample. Example The user is not currently editing samples. The character eld shows #61, that is, 61 samples have been taken. On pressing Local Control - Menu Mode 3-13 3 , the input power-level is read and stored as sample number 62. #62 is shown in the character eld. While a sample is being taken, the RUN operation-indicator lights. 4Exec5 3 The Plot Application In the Plot application the instrument takes the samples from a Stability or Logging application and generates a plot of the samples. You can only plot the samples from the most recent Stability or Logging or Manual Logging application. To make a plot of the samples you need a HPGL plotter. The plotter must be attached as the only device to the HP-IB connector on the back of the instrument. The device address of the plotter must be set to 5. To output to a plotter the instrument HPIB State must be set to Talk Only (for instructions on how to do this see \MODE" in Chapter 4). With Firmware revisions 1.7 and greater, to output to a printer or plotter, the instrument HPIB State must be set to Talk Listen (the default condition). For information on setting the HPIB Status, see \MODE" in Chapter 4. Note To nd the rmware revision, switch o the instrument, and then hold any key while the instrument is powering up. The rmware revision is shown at the bottom right of the display. Switch o the instrument and power it up again for normal operation. When you select the Plot application the character eld shows PLOT. This application has several parameters. AUTOSCAL enables or disables automatic scaling of the plot. Y_MIN sets the minimum value on the y-axis of the plot. Y_MAX sets the maximum value on the y-axis of the plot. COMMENT is an eight character message printed on the plot for identi cation. Press 4Edit5 to look at, or edit the parameters. After pressing 4Edit5, you can select parameters using 4Next5 and 4Prev5. While you are editing a parameter, the EDIT operation-indicator lights. 3-14 Local Control - Menu Mode AUTOSCAL When you select this parameter, the left side character eld shows the message AUTOSCAL. The right side character eld shows whether automatic scaling has been enabled. If automatic scaling is enabled the instrument decides the best limits for the y-axis by examining the samples. You edit the automatic scaling enable using the Modify keys. It can have the value OFF, to disable both automatic scaling, or ON, to enable automatic scaling. The displayed value is always the setting for the scaling. You can press 4Edit5 if you have nished editing, or you can press 4Next5 or 4Prev5 to edit the other parameters. The maximum and minimum values you choose for the graph, when autoscaling is o , are subject to rounding. The nal scaling is calculated to give eleven divisions of the y-axis with standard spacings (that is, spacings that are multiples of 1, 2 or 5). Y MIN You can only select this parameter when AUTOSCAL is set to OFF. When you select this parameter, the left side character eld shows the message Y_MIN. The right side character eld shows the minimum value for the y-axis of the plot. You edit the y-axis minimum value using the Modify keys. The lower limit is -800.00dBm. The higher limit is 800.00dBm. The displayed value is always the setting for the minimum. You can press 4Edit5 if you have nished editing, or you can press 4Next5 or 4Prev5 to edit the other parameters. Y MAX You can only select this parameter when AUTOSCAL is set to OFF. When you select this parameter, the left side character eld shows the message Y_MAX. The right side character eld shows the maximum value for the y-axis of the plot. You edit the y-axis maximum value using the Modify keys. The lower limit is -800.00dBm. The higher limit is 800.00dBm. The displayed value is always the setting for the maximum. You can press 4Edit5 if you have nished editing, or you can press 4Next5 or 4Prev5 to edit the other parameters. Local Control - Menu Mode 3-15 3 COMMENT When you select this parameter the left side character eld shows the message COMMENT. The right side character eld shows the comment string. The comment string is included so that you can identify the plot. 3 Note Other applications in the same channel share the COMMENT parameter. Changing this parameter in the Plot application a ects the Print application. You edit the comment using the Modify keys. There are eight characters in the comment and each of these can be a number (0 to 9), a math symbol (-, +), a space, a letter (A to Z), or punctuation symbols (!, ?, ., ,, :, ;, &, |, @, #, $, %, *, [, ], , or !). The displayed characters are always the setting for the comment. You can press 4Edit5 if you have nished editing, or you can press 4Next5 or 4Prev5 to edit the other parameters. Running the Plot Application To run the application, press 4Exec5. You cannot run the application if you are editing parameters. While the application is running, the RUN operation-indicator lights. If you try to run the plot without samples or with invalid samples, the message NO DATA, or DATA ?, shows in the character eld. The application does not run. After the plot has nished, the RUN operation-indicator switches o . 4Exec5 stops the application running. The message ABORTED shows in the character eld. Reading the Plot Figure 3-7 shows a sample plot. The areas on this gure are: The HP logo and the instrument number. The type of record application that produce the samples. This is one of STABILITY, LOGGING, or MAN LOGG. The comment. The message set up in the Plot application is included here on the plot. 3-16 Local Control - Menu Mode The rst column of data contains the parameters set in Measure mode. These are T avg, the averaging time, Cal Fact the calibration factor, Wvl, the wavelength, and Reference, the reference power-level. The reference is not included when the samples were taken as absolute values. The second column of data contains the parameters set in Menu mode for the application. These are T total, the period for which the application was taking samples, and Samples, the number of samples taken. Also in this column is the data and time at which the record application was run. The total time for the logging application consists of the averaging time and the time to process the sample. That is, a sample is only taken after the previous sample has been taken and processed. On the plot, the total time given for the logging application includes both the averaging and the processing time. Local Control - Menu Mode 3-17 3 3 Figure 3-7. Stability Plot The third column of data contains statistics based on the samples taken. These are Max, the maximum power-level sampled, Min the minimum power-level sampled, Diff, the di erence between the minimum and maximum power-levels sampled, and Avg, the mean average of the samples. Note If the samples are taken in dB or dBm, Avg is the mean average of these logarithmic values. If the samples are taken in Watts, Avg is the mean average of the linear values. The quantity on the y-axis of the plot is always power. The units can be dBm, dB, or Watts. 3-18 Local Control - Menu Mode The quantity on the x-axis of the plot is time for the plot of samples from a Stability or a Logging application, or the number of samples for the plot from a Manual Logging application. The units of time can be seconds, minutes or hours. The plot is of the power as a function of time for the Stability or Logging applications. The plot is of power as a function of the number of samples taken for the Manual Logging application. Horizontal dotted lines are drawn on the plot at the maximum, minimum and average power-levels sampled. A vertical dotted line marks the nal sample. The Print Application In the Print application the instrument takes the samples from a Stability or Logging application and generates a graphic printout of the samples. You can only printout the samples from the most recent Stability or Logging or Manual Logging application, in the selected channel. To make a printout of the samples you need a Thinkjet printer. The printer must be attached as the only device to the HP-IB connector on the back of the instrument. The device address of the printer must be set to 1. To output to a printer the instrument HPIB State must be set to Talk Only (for instructions on how to do this see \MODE" in Chapter 4). With Firmware revisions 1.7 and greater, to output to a printer or plotter, the instrument HPIB State must be set to Talk Listen (the default condition). For information on setting the HPIB Status, see \MODE" in Chapter 4. Note To nd the rmware revision, switch o the instrument, and then hold any key while the instrument is powering up. The rmware revision is shown at the bottom right of the display. Switch o the instrument and power it up again for normal operation. When you select the Print application the character eld shows PRINT. This application has several parameters. AUTOSCAL enables or disables automatic scaling of the plot. Y_MIN sets the minimum value on the y-axis of the plot. Y_MAX sets the maximum value on the y-axis of the plot. COMMENT is an eight character message printed on the plot for identi cation. Local Control - Menu Mode 3-19 3 Press 4Edit5 to look at, or edit the parameters. After pressing 4Edit5, you can select parameters using 4Next5 and 4Prev5. While you are editing a parameter, the EDIT operation- indicator lights. 3 AUTOSCAL When you select this parameter, the left side character eld shows the message AUTOSCAL. The right side character eld shows whether automatic scaling has been enabled. If automatic scaling is enabled the instrument decides the best limits for the y-axis by examining the samples. Note Other applications in the same channel share the AUTOSCAL parameter. Changing this parameter in the Print application a ects the Plot application. You edit the automatic scaling enable using the Modify keys. It can have the value OFF, to disable both automatic scaling, or ON, to enable automatic scaling. The displayed value is always the setting for the scaling. You can press 4Edit5 if you have nished editing, or you can press 4Next5 or 4Prev5 to edit the other parameters. The maximum and minimum values you choose for the graph, when autoscaling is o , are subject to rounding. The nal scaling is calculated to give eleven divisions of the y-axis with standard spacings (that is, spacings that are multiples of 1, 2 or 5). Y MIN You can only select this parameter when AUTOSCAL is set to OFF. When you select this parameter, the left side character eld shows the message Y_MIN. The right side character eld shows the minimum value for the y-axis of the plot. Note Other applications in the same channel share the Y_MIN parameter. Changing this parameter in the Print application a ects the Plot application. You edit the y-axis minimum value using the Modify keys. The lower limit is -800.00dBm. The higher limit is 800.00dBm. The displayed value is always the setting for the minimum. 3-20 Local Control - Menu Mode You can press 4Edit5 if you have nished editing, or you can press 4Next5 or 4Prev5 to edit the other parameters. Y MAX You can only select this parameter when AUTOSCAL is set to OFF. When you select this parameter, the left side character eld shows the message Y_MAX. The right side character eld shows the maximum value for the y-axis of the plot. Note Other applications in the same channel share the Y_MAX parameter. Changing this parameter in the Print application a ects the Plot application. You edit the y-axis maximum value using the Modify keys. The lower limit is -800.00dBm. The higher limit is 800.00dBm. The displayed value is always the setting for the maximum. You can press 4Edit5 if you have nished editing, or you can press 4Next5 or 4Prev5 to edit the other parameters. COMMENT When you select this parameter the left side character eld shows the message COMMENT. The right side character eld shows the comment string. The comment string is included so that you can identify the plot. Note Other applications in the same channel share the COMMENT parameter. Changing this parameter in the Print application a ects the Plot application. You edit the comment using the Modify keys. There are eight characters in the comment and each of these can be a number (0 to 9), a math symbol (-, +), a space, a letter (A to Z), or punctuation symbols (!, ?, ., ,, :, ;, &, |, @, #, $, %, *, [, ], , or !). The displayed characters are always the setting for the comment. You can press 4Edit5 if you have nished editing, or you can press 4Next5 or 4Prev5 to edit the other parameters. Local Control - Menu Mode 3-21 3 Running the Print Application 3 To run the application, press 4Exec5. You cannot run the application if you are editing parameters. While the application is running, the RUN operation-indicator lights. If you try to run the print without samples or with invalid samples, the message NO DATA, or DATA ?, shows in the character eld. The application does not run. After the print has nished, the RUN operation-indicator switches o . 4Exec5 stops the application running. The message ABORTED shows in the character eld. Reading the Printout The following gure shows a sample of the printout. 3-22 Local Control - Menu Mode 3 Figure 3-8. Logging Printout The areas on the gure are: The header contains the instrument number. Also in the printout header is the data and time at which the record application was run. The application parameters are given in three blocks. In the rst block is the type of application that took the samples. This is one of STABILITY, LOGGING, or MANUAL LOGGING. Local Control - Menu Mode 3-23 3 Also in the rst block is the Measurement type, this describes the channel used, and how the readings were made, for example, Ch. A (Absolute) when absolute readings were made in channel A, or B / REF when relative readings were made in channel B. The last element in the rst block is the comment. The message set up in the Plot application is here on the printout. The second block of data contains the parameters set in Measure mode. These are T avg, the averaging time, Cal Fact the calibration factor, Wvl, the wavelength, and Reference, the reference power-level. The reference is not included when the samples were taken as absolute values. The third block of data contains the parameters set in Menu mode for the application. These are T total, the period for which the application was taking samples, and Samples, the number of samples taken. The total time for the logging application consists of the averaging time and the time to process the sample. That is, a sample is only taken after the previous sample has been taken and processed. On the printout, the total time given for the logging application includes both the averaging and the processing time. The nal block of data contains statistics based on the samples taken. These are Max, the maximum power-level sampled, Min the minimum power-level sampled, Diff, the di erence between the minimum and maximum power-levels sampled, and Avg, the mean average of the samples. Note If the samples are taken in dB or dBm, Avg is the mean average of these logarithmic values. If the samples are taken in Watts, Avg is the mean average of the linear values. The printer now outputs a graph with the same format as the plot (see Figure 3-7). That is, The quantity on the y-axis of the graph is power. The units can be dBm, dB, or Watts. The quantity on the x-axis of the graph is time for the graph of samples from a Stability or a Logging application, or the number of samples for the graph from a Manual Logging application. The units of time can be seconds, minutes or hours. 3-24 Local Control - Menu Mode The graph is of the power as a function of time for the Stability or Logging applications. The graph is of power as a function of the number of samples taken for the Manual Logging application. Horizontal dotted lines are drawn on the graph at the maximum, minimum and average power-levels sampled. The MinMax Applications MinMax is only supplied with software versions 2.1 and later. Note To nd the rmware revision, switch o the instrument, and then hold any key while the instrument is powering up. The rmware revision is shown at the bottom right of the display. Switch o the instrument and power it up again for normal operation. The MinMax applications are intended principally for polarization dependent measurements, but can be used for other types of measurement. MinMax measures the incoming power, and displays the minimum value measured (at the bottom of the display), and the di erence between this minimum and the maximum value measured (at the top of the display). There are three modes of operation. Continuous mode, which compares each new measured value with the maximum and minimum values so far, and replaces them as necessary. This mode is useful for measuring the Polarization Dependent Loss (PDL) of a component. Run the application while sweeping the polarization of the source applied to the component. Window mode, which compares each new measured value with the maximum and minimum values for the last N samples (N, the number of samples is set by the user). Refresh mode, which compares each new measured value with the maximum and minimum values for the current N samples (N, the number of samples is set by the user). The minimum and maximum are calculated and displayed for one set of samples at a time, after the full set of samples have been measured. Local Control - Menu Mode 3-25 3 The Window and Refresh modes are for use, for example, when you are searching for or setting the position of minimum PDL. Note 3 The length of the window, or the refresh period must be shorter than the rate at which you are changing the polarization, in this case. Figure 3-9. The Window and Refresh Modes 3-26 Local Control - Menu Mode MODE This is the parameter which chooses the mode, CONT selects the continuous mode, WINDOW selects the Window mode, and REFRESH selects the Refresh mode. 3 SAMPLES This is the parameter which sets the length of the Window or Refresh mode. It is possible to use up to 500 samples in the Window mode. It is possible to use up to 10000 samples in the Refresh mode. The length of the window or the refresh period is set by the number of samples, and the averaging time. The averaging time is set in Measure mode. Running the MinMax Application To run the application, press 4Exec5. You cannot run the application if you are editing parameters (press 4Edit5 again, to nish editing parameters). While the application is running, the RUN operation-indicator lights. While the application is running, the result eld shows the di erence between minimum and maximum measurements, and the character eld shows the minimum measurement. 4Pause5 suspends the running of the application. While the application is paused, the power level is shown in the result eld. You can restart the MinMax application by pressing 4Pause5 a second time. 4Exec5 stops the application running. Local Control - Menu Mode 3-27 The More Key gets you into the other applications. The full list of these applications depends on the modules that you have installed. There are two that are standard, these come with the mainframe. They are the show and the alignment applications. After pressing 4More5, you choose an application using 4Next5, 4More5 or 4Prev5. 4More5 acts in the same way as 4Next5. The application is displayed in the character eld of the selected channel. 4More5 3 The Show Application In the Show application you can look at the samples from a Stability or Logging application. You can only look at the samples from the most recent Stability or Logging or Manual Logging application. When you select the Show application the character eld shows SHOW. This application has no parameters that can be modi ed. Press 4Edit5 to look at the stored values. While you are looking at the stored values, the EDIT operation-indicator lights. To move from one value to another you use 4Prev5 and 4Next5. MAXIMUM When MAXIMUM shows in the left side character eld, the value in the right side character eld is the maximum power-level sampled. MINIMUM When MINIMUM shows in the left side character eld, the value in the right side character eld is the minimum power-level sampled. 3-28 Local Control - Menu Mode DIFF When DIFF shows in the left side character eld, the value in the right side character eld is the di erence between the minimum and maximum power-levels sampled. 3 AVERAGE When AVERAGE shows in the left side character eld, the value in the right side character eld is the mean average of the samples. Note If the samples are taken in dB or dBm, Avg is the mean average of these logarithmic values. If the samples are taken in Watts, Avg is the mean average of the linear values. #1 When # 1 shows in the left side character eld, the value in the right side character eld is the rst of the samples taken. To examine the rest of the samples, use the Modify keys. In this case the Modify keys operate on the value in the left side character eld. The Alignment Application The Alignment application simpli es the alignment of two optical components to get the best transfer of power from one to the other. Preparation You need a sensor module to perform the Alignment application. The only hardware setup you need is to have the device under test connected to the sensor. Local Control - Menu Mode 3-29 3 Figure 3-10. Setup for an Alignment Application Before you start the Alignment application, make sure that you have set all the measurement-parameters that you use. It is most important to make sure that you have set T and for the sensor. If you are already in Menu mode, you have to return to Measure mode to set these parameters. When you select the Alignment application the character eld shows ALIGNMNT. This application has several parameters. TYPE sets whether the instrument automatically records the maximum power-level, or the user sets the maximum power-level. DELTA sets the range of power shown by the graphic bar. MAXPOWER sets the maximum power- level. All the other parameters (Wavelength, Tavg , etc.) use the values given to them in measure mode. Press 4Edit5 to look at, or edit the parameters. After pressing 4Edit5, you can select parameters using 4Next5 and 4Prev5. While you are editing a parameter, the EDIT operation-indicator lights.

If TYPE is set to AUTO, the maximum power-level is the maximum input power-level read since the application started. If TYPE is set to MANUAL, the maximum power-level is set by MAXPOWER. The right side result eld shows the input power-level, in dB, relative to the maximum power-level. Local Control - Menu Mode 3-31 3 3 Figure 3-11. The Display during the Alignment Application The character eld shows the input power-level graphically. The right end of the character eld always represents the maximum power-level. The left end of the character eld represents Pmax 0 1P, where Pmax is the maximum power-level, and 1P is determined by DELTA. Pressing 4*5 and 4+5 changes 1P. When the the graph is seven dots high, 1P is equal to DELTA. If you press 4*5, 1P is now equal to half the value of DELTA and the graph is shown ve dots high. If you press 4*5 a second time, 1P is equal to a quarter the value of DELTA and the graph is shown three dots high. Example DELTA is set to 1.00dB. MAXPOWER is set to 1.00dBm. The right end of the graph represents 1.00dBm. At the start of the application The left end of the graph represents 0.00dBm. 4*5 is pressed twice. The left end of the graph represents 0.75dBm. The graph is three dots high. 4+5 is pressed once. The left end of the graph represents 0.50dBm. The graph is ve dots high. If only the last column of dots on the left is lit, the power-level is outside the limits set by Pmax 0 1P and Pmax 4Pause5 enables and disables the tone. The frequency of the tone increases with input power-level. The lowest frequency corresponds to the left side of the power graph in the character eld. The highest frequency corresponds to the right side of the power graph in the character eld. If the power-level is outside the limits set by Pmax 0 1P and Pmax , no tone sounds. 3-32 Local Control - Menu Mode 4Exec5 stops the application running. 3 Local Control - Menu Mode 3-33 4 System Mode System mode is where you set the con gurations that a ect the instrument as a whole.

Descriptions for the actual commands for the HP 8153A, are in the following chapters. Programming information is speci c to the HP 8153A, and assumes that you are already familiar with using the HP-IB. If you are not familiar with the HP-IB, then refer to the following books: Hewlett-Packard Company. Tutorial Description of Hewlett-Packard Interface Bus, 1987.

While RMT in remote the only key you can use is 4Local5. If local lockout is enabled, then you cannot use any keys. (service request) indicator shows when the HP 8153A has SRQ requested service. NNNNNNNNNNN NNNNNNNNNNN 5-2 Remote Operation You cannot control the instrument over the HP-IB if the TLK ONLY indicator is lit. If this indicator is lit, see \MODE" in Chapter 4 for details on how to change the HP-IB state. NNNNNNNNNNN NNNNNNNNNNNNNN The Parser The parser is responsible for reading in messages from the interface, converting them into commands, and then performing those commands. Normally, the instrument takes all the incoming data from the interface port and puts it in the input queue. When all the data is in the queue, it is parsed. When the input queue is full, and there are additional bytes at the interface, the parser 1. removes one byte from the input queue 2. parses it, 3. then takes a byte from the interface port and puts it in input queue. These three steps are repeated until there are no additional bytes at the interface. Parser Type Beside the HP 8153A commands, the instrument also has a parser that can use the HP 8152A commands. You can only choose between the parsers from the front panel in system mode, see \LANGUAGE" in Chapter 4. Synchronization Most of the commands and queries described are executed when parsed. There are some exceptions for which execution continues afterward. These fall into three categories. 1. Trigger commands. 2. Measurement commands. 3. The Zero command. These commands block further execution in the same channel until they have nished. Commands in the second channel are executed independently. You can control synchronization for these commands by using the *OPC, *OPC?, and the *WAI commands (see Chapter 6 for more details on these commands). Remote Operation 5-3 5 Note To make sure that a command has nished executing, check the Operation Complete bit in the Event Status Register.

In particular, if you are running a Record application over the HP-IB, you should not poll the instrument continuously to detect the end of the application. Instead, you should use interrupts, if this is possible, or make sure that there is a delay between each poll of the instrument. A programming example, using interrupts for a stability application, is included in chapter 6, see \Example 6" in Chapter 10. If the instrument is accessed over the HP-IB while you are editing a parameter, the editing will be terminated. For example, if you are editing a system parameter, an incoming HP-IB access terminates the editing, and blanks the display; in this case you should press 4Local5 and then 4Menu5 to restore the display and return the instrument to Measure mode. If the interrupting HP-IB command is to zero the instrument, then the ZEROING message is lost when the display is blanked. TMSL The HP 8153A uses commands according to the Test and Measurement Systems Language (TMSL, also known as Standard Commands for Programmable Instrumentation, SCPI). For an introduction to TMSL/SCPI, and TMSL/SCPI programming techniques, refer to the following documents: Hewlett-Packard Press (Addison-Wesley Publishing Company, Inci). A Beginners Guide to SCPI. Barry Eppler. 1991. The SCPI Consortium. Standard Commands for Programmable Instruments. Published periodically by various publishers. To obtain a copy of this manual, contact your Hewlett-Packard representative. A TMSL/SCPI command is a combination of command components. The commands used by the HP 8153A are given in chapters 7, 8 and 9. These show the possible command components, and the possible component combinations. The rst component in one of the command tables is called the root component. Other components are added to make a command. The way the components are added is called the command path. It is important to know the current path, because the same component can be used in di erent paths. In some cases the 5-6 Remote Operation command contains components which are included to maintain compatibility to the TMSL Standard. The command table always starts with a root component. Other components that are indented to the right can be added to the current path to complete a command, or to make a new command. Example We will use the SOURce Command for our examples. The command table for SOURce is as follows SOURce Command Command SOURce[1j2] :AM [:INTernal] :FREQuency :FREQuency? :POWer :ATTenuation[1j2] :ATTenuation[1j2]? :STATe :STATe? :WAVElength :WAVElength? Summary Parameter [ ]jCW [ ] UPPerjLOWerjBOTH An example of a command from this table is SOURCE:POWER:STATE. In addition to the components, some commands also need data. A piece of data is called a parameter. Separate a command and its parameters by whitespace characters (spaces or tabs). Use a comma (,) to separate parameters when a command needs more than one of them. Example An example of a command with a parameter is SOURCE:AM:INTERNAL:FREQUENCY CW. Put a colon (:) before any component to indicate a move to the next level of the combination. Put a semi-colon (;) before a component to indicate another command at the same level of the combination. Example An example of using colons and semicolons to save typing is SOUR:POW:ATT 1.0; STAT ON; WAVE LOW Remote Operation 5-7 5 This is the same as SOURCE:POWER:ATTENUATION 1.0 SOURCE:POWER:STATE ON SOURCE:POWER:WAVELENGTH LOWER A semi-colon followed by a colon (;:) sets the path back to the root level. The command can be written in upper case or in lower case. The components can be typed in full, or they can be shortened. The full version is in the command table in both upper and lower case letters. The shortened version of a command is that part which is shown in upper case. Example The command SOURCE:POWER:STATE ON can also be written in lower case as source:power:state on or it can be shortened and written as 5 sour:pow:stat on Setting the HP-IB Address You can only set the HP-IB address from the front panel. See \ADDRESS" in Chapter 4. The HP-IB refuses to accept a new HP-IB address if it is in the remote state, or if it is addressed either as a listener or as a talker. Return the HP 8153A to local control (via controller) before changing the address. The default HP-IB address is 22. 5-8 Remote Operation Syntax Diagram Conventions The following symbols describe the syntax of commands in the following chapters. < ... > The characters between angled brackets show the kind of data that you require, or that you get in a response. You do not type the angled brackets in the actual message. application is an application name. The names which are available depend upon the modules installed. boolean this can be data (ON or OFF), or a number. Any non- zero value is an ON. In a response you get 0, for OFF, or 1, for ON. day is a number in the range 1 to 28, 1 to 29, 1 to 30 or 1 to 31. It is the day of the month in the date. The range used depends on the values of \year" and \month" parameters. hour is a number in the range 0 to 23. It is the hours in the time. minute is a number in the range 0 to 59. It is the minutes in the time. month is a number in the range 1 to 12. It is the month in the date. node is a node name. A node is the name of a position in the structure of the status registers. second is a number in the range 1 to 60. It is the seconds in the time. Setting second to 60 will automatically increment the other elements of the time. string is ascii data. unit is one of DB, DBM, W (Watts), M (meters), or S (seconds), or one of NW or MW, NM, or MS. It is the units in a value. value is numeric data in one of the forms described below (NR1, NR2, NR3, or NRf). Remote Operation 5-9 5 varname 5 is the name of a variable for use with an application. The varname available depend on the application. wsp is a white space. year is a number in the range 1990 to 2089. This is the years in the date. Other kinds of data are described as required. [ ... ] The characters between square brackets show optional information that you can include with the message. j The bar shows an either-or choice of data, for example, ajb means either a or b, but not both simultaneously. All characters not between angled brackets are terminal symbols and must be sent exactly as shown. Items between angled brackets are non-terminal symbols, descriptions of these items follow the syntax description. Spaces are ignored; they can be inserted to improve readability. The response format speci es what the instrument returns in response to a query. All responses are terminated with a with the HP-IB EOI (bus management line) active. There are four types of number that are used in responses. These are de ned by the IEEE standard. NR1 This is a number of the form [+j-]number where number is any number of digits without a decimal point. NR2 Examples of NR1 are 3, +27, -56. This is a number of the form [+j-]number.number, where number is any number of digits without a decimal point. 5-10 Remote Operation NR3 Examples of numbers in NR2 format are 33.23, +15.02376, -123.098. This is a number of the form [+j-]number.numberE+j-number, where number is any number of digits without a decimal point. 5 Examples of numbers in NRf format are 3.27E-56, +33.32E+15, -0.2376E-11. NRf is a number with any of the formats described above. In this manual we use these format types to describe entered data as well as response data. A general description of entered data is given in the diagram here Remote Operation 5-11 6 Common Commands The IEEE 488.2 standard has a list of reserved commands, called these common commands. Some of these commands must be implemented by any instrument using the standard, others are optional. The HP 8153A implements all the necessary commands, and some optional ones. This chapter describes the implemented commands. Common Status Information There are four registers involved in the status information available from the instrument when you use the common commands. Two of these are status-registers and two are enable-registers. These registers conform to the IEEE Standard 488.2-1987. You can nd further descriptions of these registers under \*ESE", \*ESR?", \*SRE", and \*STB?". The following gure shows how the registers are organized. Remote Operation - Common Commands 6-1 6 6 Note Figure 6-1. Common Status Registers Unused bits in any of the registers return 0 when you read them. 6-2 Remote Operation - Common Commands SRQ, The Service Request A service request (SRQ) is forced when a bit in the Status Byte register goes from 0 ! 1 AND the corresponding Service Request Enable Mask bit is set. If an SRQ is forced, the Request Service (RQS) bit is set to 1. This bit remains at 1 until read by a serial poll, even if the reason or condition that caused the service request no longer exists. Similarly, if a serial poll reads the RQS it is reset to 0, even if the condition that caused the service request still exists. The serial poll command transfers the value of the Status Byte register to a variable. Input Queue The input queue is a FIFO queue ( rst-in rst-out) and is 1024 bytes long. Output Queue The output queue is a FIFO queue ( rst-in rst-out) and is 274 bytes long. The message available, Message Available (MAV), bit is set in bit four of the Status Byte register whenever the output queue is not empty. Receiving a new program message clears the output queue and the Message Available (MAV) bit. This happens directly after the program message terminator is received. Error Queue The error queue is a FIFO queue ( rst-in rst-out) and is 30 errors long. That is, the oldest error is the rst error to be read. If the queue over ows, message '-350 ' overlays the last message in the queue. Remote Operation - Common Commands 6-3 6 Table 6-1.

OUTPUT 722;"*WAI" 6 Remote Operation - Common Commands 6-15 7 HP-IB Status Commands This chapter gives a list of the HP 8153A HP-IB commands and queries used for determining the status of the instrument. The Status Registers The building blocks of the status information circuitry are three types of register, and two kinds of transition lters. These registers and lters are grouped together to make a node. Each node has a condition register, a positive transition register, a negative transition register, an event register and an enable register. 7 Note Figure 7-1. The Registers and Filters in a Node The most signi cant bit of these registers is not used. That is, these registers use only bits 0 to 14. Remote Operation - Status Commands 7-1 The Condition Registers You can read a condition register at any time to nd the current status of the node. It is updated continuously. Reading a condition register does not change its contents. The Transition Filters The transition lters are of two types, a positive transition lter and a negative transition lter. A 1 in a bit of the transition lter enables that bit. An enabled bit in a positive transition lter generates a 1 at the output when the input goes from 0 to 1. An enabled bit in a negative transition lter generates a 1 at the output when the input goes from 1 to 0. The condition register provides the input to the lters. The output is sent to the event register. At power up, all of the bits in both transition registers are set to 0. That is, no transitions are passed to the event registers. The Event Registers The outputs from the transition lters set the bits in the event register. These bits are only cleared when the register is read, otherwise they stay as they are. 7 The Enable Registers The enable register selects which bits a ect the next stage of registers. A 1 in a bit in the enable register, means that the corresponding bit in the event register is enabled. The enabled bits are ORed together and the result is sent to the condition register in the next node. At power up, all of the bits in the enable registers are set to 0. 7-2 Remote Operation - Status Commands The Status Commands The registers and lters described above, are present in each node of the status structure (the full structure is given later in this chapter). Each node has the same set of commands and queries. These commands and queries are listed here once to avoid repetition. Note Note You can only use these commands and queries with a node speci cation. The syntax element means any of the node speci cations. The commands and queries are given in upper and lower case. You can use either the entire command or query (both upper and lower case), or just the part that is in upper case. That is, either STATUS:OPERATION:SETTLING:EVENT? or STAT:OPER:SETT:EVEN? is acceptable. The commands and queries can be entered in either upper or lower case. That is either STAT:OPER:SETT:EVEN? or stat:oper:sett:even? is acceptable. STATus:PRESet Syntax Note Description STATus:PRESet You do not specify a node with this command. 7 This command presets all the enable registers and transition lters for all nodes of the OPERational and QUEStionable status. The OPERational, QUEStionable, and ISUMmary nodes are set: Remote Operation - Status Commands 7-3 Register All bits set to ENABle PTRansition NTRansition 0 1 0 The OPERation:CORRecting:ZERO, OPERation:AVERaging:POWer, OPERation:MEASure:POWer and any OPERation:POWer: nodes are set: Register All bits set to ENABle PTRansition NTRansition 1 0 1 All other nodes are set: Register All bits set to ENABle PTRansition NTRansition 7 Related Commands Example 1 1 0 None. OUTPUT 722;"STAT:PRES" STATus: :CONDition? Syntax Response Description Related Commands STATus: :CONDition? 0 value 32767 This query returns the value for the condition register for the node. The value is returned as an integer (NR1). None. 7-4 Remote Operation - Status Commands Example OUTPUT 722;"STAT:OPER:TRIG:POW:COND?" ENTER 722;A$ STATus: :ENABle Syntax Description Related Commands Example STATus: :ENABle 0 value 32767 This command sets the enable register for the node. You send the value as an integer (NRf). A 1 in any bit of this register enables that bit in the event register. All the enabled bits are ORed together and the result of this OR is sent to the next node. STAT: :ENAB? OUTPUT 722;"STAT:OPER:TRIG:POW:ENAB 3" STATus: :ENABle? Syntax Response Description Related Commands Example STATus: :ENABle? 0 value 32767 This query returns the setting for the enable register for the node. The value is returned as an integer (NR1). STAT: :ENAB OUTPUT 722;"STAT:QUES:POW:ENAB?" ENTER 722;A$ STATus: [:EVENt]? Syntax Response Description STATus: [:EVENt]? 0 value 32767 This query returns the value for the event register for the node. The value is returned as an integer (NR1). Once you have read the event register, its contents are cleared. Remote Operation - Status Commands 7-5 7 Related Commands Example None. OUTPUT 722;"STAT:OPER:SETT:EVEN?" ENTER 722;A$ STATus: :NTRansition Syntax Description Related Commands Example STATus: :NTRansition 0 value 32767 This command sets the negative transition lter for the node. You send the value as an integer (NRf). A 1 in any bit of this register enables the negative transition. That is, if a bit is set to 1 and the corresponding bit at the input changes from 1 to 0, the output goes to 1. STAT: :NTR? OUTPUT 722;"STAT:QUES:POW:OVERR:NTR 3" STATus: :NTRansition? Syntax Response Description 7 Related Commands Example STATus: :NTRansition? 0 value 32767 This query returns the value for the setting of the negative transition lter for the node.

ENTER 722;A$ STATus: :PTRansition Syntax Description STATus: :PTRansition 0 value 32767 This command sets the positive transition lter for the node. You send the value as an integer (NRf). A 1 in any bit of this register enables the negative transition. That is, 7-6 Remote Operation - Status Commands Related Commands Example if a bit is set to 1 and the corresponding bit at the input changes from 0 to 1, the output goes to 1. STAT: :PTR?

The value is returned as an integer (NR1). STAT: :PTR OUTPUT 722;"STAT:QUES:POW:OVERR:PTR?" ENTER 722;A$ The Operation Status The operation status is that part of the status structure that shows the normal operation of the instrument. The relationship between the nodes of the operation status is shown in Figure 7-2. Each node (except the status byte) is sixteen bits wide. Only 15 of these bits are used. Each node (except the status byte) has it's own condition, event and enable registers, and it's own transition lters. These registers and lters are described earlier in this chapter. Remote Operation - Status Commands 7-7 7 7 Figure 7-2. The Operation Registers 7-8 Remote Operation - Status Commands The Operation Status Commands The following is a complete list of the operation status commands and queries. These commands and queries are available, without regard to the con guration of the instrument. Some nodes are only active with certain modules. For example, the averaging registers are not used if the instrument has two source modules. Here, you can read the averaging event register, but it always returns a 0. Table 7-1.

Bit 7 of the status byte summarizes this node. 7-10 Remote Operation - Status Commands The OPERation:SETTling Node This node gives a summary of the peltier settling nodes. Bit 0 returns the status of the LPELTier node. Bit 1 returns the status of the HPELTier node. The HPELTier node is only active for a dual wavelength source module, the other modules use only LPELTier. A 1 means that the instrument is settling or has settled. Bit 1 of the OPERation node summarizes this node. The OPERation:SETTling:LPELTier Node This node gives a summary of the peltier settling.

FETCh Command Summary Command Parameter FETCh[1j2] [:SCALar] :POWER [:DC]? Specifying the Channel You specify the channel by attaching a numeric sux to the FETCh mnemonic. You access channel A by using FETCh1, you access channel B by using FETCh2. If you do not add a sux to the mnemonic, channel A is assumed. FETCh[:SCALar]:POWer[:DC] Syntax Response Description 8 FETCh[1j2][:SCALar]:POWer[:DC]? This command gets a reading from the module. It does not provide it's own triggering and so must be used with either a continuous or a preceding immediate trigger. The value read back is a oating point number in exponential number (NR3). The units of the number read back depend on whether the absolute or relative measurement mode is being used, and which units have been selected. The possible units are Watts, dBm, or dB. For averaging times of 1 second or less, a new measurement is available at the end of the averaging time. This is drawn in Figure 8-1. A measurement is available at the rst x if an immediate trigger is used. A measurement is available display at each x when continuous triggering is used. 8-4 Remote Operation - Commands Figure 8-1. Measurements with TAverage 1 second For averaging times of more than 1 second, the x value is given by the formula Tsample 1 0 Tsample + Sample xnew = xold Tavg Tavg Where xnew xold Sample Tavg Tsample is the new result, is the previous result, is the value read by the hardware, is the averaging time (as set by the user), and is the time taken, by the hardware, to make a reading. When a continuous trigger is used for averaging times of more than 1 second, the rst measurement is available at the end of the averaging time. The second measurement is available 1 second later, and a new measurement is available every second after that. Each of these new measurements is the average for the readings of the preceding period. This is shown in Figure 8-2, TAverage is 5s. First measurement is available at x1 , which is the average for readings in the period TAverage . The second measurement is available at x2, and so on. 8 Figure 8-2. Measurements with TAverage > 1 second, continuous triggering. Remote Operation - Commands 8-5 When an immediate trigger is used for averaging times of more than 1 second, the rst measurement is available at the end of the averaging time. The second measurement is available again at the end of the averaging time (once another trigger has been made), and so on. This is shown in Figure 8-3, TAverage is 5s. First measurement is available at x1 , which is the average for readings in the period T1 . The second measurement is available at x2, which is the average for the readings in the period T2 . Again in this case, the value is calculated by the formula Tsample 1 0 Tsample + Sample xnew = xold Tavg Where xnew xold Sample Tavg Tsample Tavg is the new result, is the previous result, is the value read by the hardware, is the averaging time (as set by the user), and is the time taken, by the hardware, to make a reading.

The commands are grouped according to the modules to which they refer. A list of the commands for a module are supplied with that module. Install the relevant pages into this chapter each time you add a module to your system. Program Commands All the applications are run using the PROGram commands. The applications do not automatically enable local lockout. It is possible for someone to disturb an application that is under remote control by using the front panel keys. To avoid this, you can activate the local lockout. It is possible to disturb an application by sending programming commands to the channel in which the application is running. Use the status commands to check that the application has nished before sending any more commands to the channel. 9 Remote Operation - Application Commands 9-1 Table 9-1.

It also includes information about initial inspection and damage claims, preparation for use, packaging, storage, and shipment. Safety Considerations The Model HP 8153A is a Class 1 instrument (that is, an instrument with an exposed metal chassis directly connected to earth via the power supply cable). The symbol used to show a protective earth terminal in the instrument is . Before operation, you should review the instrument and manual, including the red safety page, for safety markings and instructions. You must follow these to ensure safe operation and to maintain the instrument in safe condition. Some HP 8153A circuits are powered whenever the instrument is connected to the AC power source. To disconnect from the line power, disconnect the power cord either at the rear power-inlet or at the AC line-power source (receptacle). One of these must always be accessible. If the instrument is in a cabinet, it must be disconnected from the line power by the system's line-power switch. Installation A-1 A A Initial Inspection Inspect the shipping container for damage. If there is damage to the container or cushioning, you should keep them until you have checked the contents of the shipment for completeness and veri ed the instrument both mechanically and electrically. The Performance Tests give procedures for checking the operation of the instrument. If the contents are incomplete, mechanical damage or defect is apparent, or if an instrument does not pass the operator's checks, notify the nearest Hewlett-Packard oce. Warning To avoid hazardous electrical shock, do not perform electrical tests when there are signs of shipping damage to any portion of the outer enclosure (covers, panels, etc.). Line Power Requirements The HP 8153A can operate from any single-phase AC power source that supplies between 100V and 240V at a frequency in the range from 50 to 60Hz. The maximum power consumption is 55VA with all options installed. The fuse used by this instrument is T1A / 250V (slow) (HP Part No. 2110-0007). Changing the fuse should be carried out only by a quali ed electrician or by HP service personnel as it is necessary to open the instrument. Line Power Cable In accordance with international safety standards, this instrument has a three-wire power cable. When connected to an appropriate AC power receptacle, this cable earths the instrument cabinet. The type of power cable shipped with each instrument depends on the country of destination. Refer to Figure A-1 for the part numbers of the power cables available. A-2 Installation Warning To avoid the possibility of injury or death, you must observe the following precautions before switching on the instrument. If this instrument is to be energized via an autotransformer for voltage reduction, ensure that the Common terminal connects to the earthed pole of the power source. Insert the power cable plug only into a socket outlet provided with a protective earth contact. Do not negate this protective action by the using an extension cord without a protective conductor. Before switching on the instrument, the protective earth terminal of the instrument must be connected to a protective conductor. You can do this by using the power cord supplied with the instrument. It is prohibited to interrupt the protective earth connection intentionally. Installation A-3 A A Figure A-1. Line Power Cables - Plug Identi cation The following work should be carried out by a quali ed electrician, and all local electrical codes must be strictly observed. If the plug on the cable does not t the power outlet, or if the cable is to be attached to a terminal block, cut the cable at the plug end and rewire it. The color coding used in the cable depends on the cable supplied. If you are connecting a new plug, it should meet the local safety requirements and include the following features: Adequate load-carrying capacity (see table of speci cations). Ground connection. Cable clamp. Operating Environment The following summarizes the HP 8153A operating environment ranges. In order for the HP 8153A to meet speci cations, the operating environment must be within these limits. Warning A-4 Installation The HP 8153A is not designed for outdoor use. To prevent potential re or shock hazard, do not expose the HP 8153A to rain or other excessive moisture. Temperature A The HP 8153A may be operated in temperatures from 0 C to 55 C. Humidity The HP 8153A may be operated in environments with humidity up to 95% (0 C to +40 C). The HP 8153A should be protected from temperatures or temperature changes that cause condensation within the instrument. Instrument Cooling The HP 8153A has a cooling fan mounted internally. Mount or position the instrument so that air can circulate through it freely. When operating the HP 8153A, choose a location that provides at least 75mm (3inches) of clearance at the rear, and at least 25mm (1inch) of clearance at each side. Failure to provide adequate air clearance may result in excessive internal temperature, reducing instrument reliability. Input/Output Signals Caution A maximum of 15V can be applied as an external voltage to any of the BNC connectors. HP-IB Interface You can connect your HP-IB interface into a star network, a linear network, or a combination star and linear network. The limitations imposed on this network are as follows: The total cable length cannot exceed 20 meters The maximum cable length per device is 2 meters No more than 15 devices may be interconnected on one bus. Installation A-5 A Cables and Adapters The HP-IB connector is compatible with the connectors on the following cables and adapter. HP-IB Cable, 10833A, 1 m (3.3 ft.) HP-IB Cable, 10833B, 2 m (6.6 ft.) HP-IB Cable, 10833C, 4 m (13.2 ft.) HP-IB Cable, 10833D, 0.5 m (1.6 ft.) HP-IB Adapter, 10834A, 2.3 cm. extender. Connector The following gure shows the connector and pin assignments. Connector Part Number: 1251-0293 Caution A-6 Installation Figure A-2. HP-IB Connector HP products delivered now are equipped with connectors having ISO metric-threaded lock screws and stud mounts (ISO M3.5x0.6) that are black in color. Earlier connectors may have lock screws and stud mounts with English- threaded lock screws and stud mounts (6-32 UNC) that have a shiny nickel nish. Caution It is recommended that you do not stack more than three connectors, one on top of the other. Hand-tighten the connector lock screws. Do not use a screwdriver. HP-IB Logic Levels The HP 8153A HP-IB lines use standard TTL logic, as follows: True = Low = digital ground or 0Vdc to 0.4Vdc False = High = open or 2.5Vdc to 5Vdc All HP-IB lines have LOW assertion states. High states are held at 3.0Vdc by pull-ups within the instrument. When a line functions as an input, it requires approximately 3.2mA to pull it low through a closure to digital ground. When a line functions as an output, it will sink up to 48mA in the low state and approximately 0.6mA in the high state. Note The HP-IB line screens are not isolated from ground. Removing and Fitting Modules The unit can t two single width modules, or one double width module. How to Remove a Module Caution Do not use the electrical or optical connectors to pull the module out of the instrument, as this can cause damage to the connectors. Make sure that the line power is switched o before you remove a module. Installation A-7 A A Figure A-3. How to Remove a Module 1. Lift the catch at the bottom front of the module. 2. With the catch lifted, pull the module out of the instrument. If the module does not slide out freely, check that you have lifted the catch high enough. How to Fit a Module Caution A-8 Installation Do not use the electrical or optical connectors to push the module into the instrument, as this can cause damage to the connectors. Make sure that the line power is switched o before you t a module. A Figure A-4. Fitting a Module 1. Position the module at an unoccupied slot, with the catch at the bottom front of the module. 2. Insert the module into the slot and onto the tracks. If the module does not slide in freely, check that you have correctly positioned and correctly oriented it and that there is no obstruction to its movement. 3. Apply pressure to the front panel, and push the module as far as it goes. You hear a small click when the module reaches its installed position. This is the catch making contact. Storage and Shipment The instrument can be stored or shipped at temperatures between 040 C and +70 C. The instrument should be protected from temperature extremes that may cause condensation within it. Installation A-9 A Claims and Repackaging If physical damage is evident or if the instrument does not meet speci cation when received, notify the carrier and the nearest Hewlett-Packard Service Oce. The Sales/Service Oce will arrange for repair or replacement of the unit without waiting for settlement of the claim against the carrier. Return Shipments to HP If the instrument is to be shipped to a Hewlett-Packard Sales/Service Oce, attach a tag showing owner, return address, model number and full serial number and the type of service required. The original shipping carton and packing material may be reusable, but the Hewlett-Packard Sales/Service Oce will provide information and recommendation on materials to be used if the original packing is no longer available or reusable. General instructions for repacking are as follows: 1. Wrap instrument in heavy paper or plastic. 2. Use strong shipping container. A double wall carton made of 350- pound test material is adequate. 3. Use enough shock absorbing material (3 to 4 inch layer) around all sides of the instrument to provide a rm cushion and prevent movement inside container. Protect control panel with cardboard. 4.

G G-10 Remote Operation H HP 8152A HP-IB Command Summary The HP 8153A o ers you a compatibility mode where you can program the instrument using the HP-IB commands for the HP8152A Average Power Meter. A summary of this set of commands is given here. For more details refer to the HP 8152A Operating and Programming manual. (HP part number 08152-90001). Di erences Note Dissimilarities in hardware and the principles of local operation, mean that in some cases di erences between the HP 8152A and the HP 8153A in compatibility mode cannot be avoided. 1. The DB(MW) unit is no longer available. Use DBM instead. 2. In the standard parameter set, the AUTOranging is no longer set to o . AUTOranging is set to on, this also means that the Range is not set to 0dBm. 3. The CAL? and WCAL? queries are no longer available. 4. The power reading can no longer be made by just reading a value from the output queue. A query command must be sent to make a reading. Use the FETCh query as described in the TMSL mode. An example of using FETCh is given after this list. 5. When there is no sensor in one of the channels, the CH3 command sets the System Error bit (bit 7) and the Parameter Error bit (bit 0) in the status byte. The channel selection is not changed. 6. When an attempt is made to read the wavelength of a channel which has no sensor, with the WVL? command, the response is unde ned. 7. The responses for the ERR? and LERR? queries are Remote Operation H-1 H 100 Zero failed, channel A. 142 Head read error, channel A. 200 Zero failed, channel B. 242 Head read error, channel B. 8. Avoid altering parameters under local control when the instrument is also being controlled over the HP-IB in compatibility mode. It is possible to alter the parameters in such a way that the instrument no longer behaves like an HP 8152A. Note When in compatibility mode, altering the units (dBm, dB, Watts) under local control will not change the units used under remote control. 9. On the occurance of a syntax error in compatibility mode, the parser resynchronizes at the start of the next line. Any commands following the syntax error on the same line, will be ignored. The HP 8152A resynchronizes on the next command that it recognizes. Example Two lines in a program are: CH1;Q1;CH2;U1 CH? The Q1 command will cause a syntax error. The HP 8152A selects channel A. After the syntax error it continues with selecting channel B and setting the units there to Watts. It will respond with 2 to the query. The HP 8153A in compatibility mode selects channel A. After the syntax error the rest of the line is ignored. It will respond with 1 to the query. 10. The setting for the instrument in compatibility mode is not stored in the battery backed up memory. H H-2 Remote Operation Using the FETCh Command - An Example This example is a subroutine to take a reading from the second channel of the power meter. The original program, as written for the HP 8152A is given on the left. The modi ed program, to run on the HP 8153A (in HP8152A Compatibility mode), is given on the right.

Do not specify a channel as part of the FETCh command, that is, the syntax for the command in the compatibility mode is FETCh[:SCALar]:POWer[:DC]? Declares the subroutine. P$ is the string in which the reading is returned to the calling program. Clears all the HP-IB bu ers. (Pmm is the HP-IB address of the instrument) Clears the Status Byte in the instrument. Sets up the instrument: Sets the wavelength for channel 2 to 1301nm; select MEASure mode; select channel 2; select dBm as the units; set the trigger on; enable autoranging. Trigger the instrument. Performs a serial poll of the instrument, until bit 2 in the Status Byte is set. This is the extra command required by the HP 8153A when in HP 8152A compatibility mode to read a value Remote Operation H-3 H 1370 1390, 1400 Read the value. Return the instrument to local state, and leave the subroutine. Setting the Filter The lter command on the HP 8152A selects between a 2Hz ( lter ON) and an 8Hz (Filter OFF) low pass lter. This lter is not available on the HP 8153A. The lter command in HP 8152A Compatibility mode selects between an averaging time of 500ms ( lter ON) and an averaging time of 200ms ( lter OFF). Switching the instrument into HP 8152A Compatibility mode, does not alter the averaging time. You should use *RST, or a lter ON or OFF command to set the averaging time to 500ms or 200ms.

The plot or printout is not scaled in Watts. Backdating K-1 Instruments with Serial Numbers 2946G00225 and Earlier K The Print Application In the Print application the instrument takes the samples from a Stability or Logging application and generates a printout of the samples. You can only printout the samples from the most recent Stability or Logging or Manual Logging application. When you select the Print application the character eld shows PRINT. This application has two parameters. SAMPLE sets the number of samples printed out. COMMENT is an eight character message printed on the printout for identi cation. Press 4Edit5 to look at, or edit the parameter. While you are editing a parameter, the EDIT operation-indicator lights. SAMPLES When you select this parameter, the left side character eld shows the message SAMPLES. The right side character eld shows the number of samples that will be printed. You edit the number of samples to be printed. The lower limit is 0. The higher limit is 500. The displayed value is always the setting for the samples. Press 4Edit5 when you have nished editing. COMMENT When you select this parameter the left side character eld shows the message COMMENT. The right side character eld shows the comment string. The comment string is included so that you can identify the printout. Note Other applications in the same channel share the COMMENT parameter. Changing this parameter in the Print application a ects the Plot application. You edit the comment using the Modify keys. There are eight characters in the comment and each of these can be a number (0 to 9), a math symbol (-, +), a space, a letter (A to Z), or punctuation symbols (!, ?, ., ,, :, ;, &, |, @, K-2 Backdating #, $, %, *, [, ], , or !). The displayed characters are always the setting for the comment. You can press 4Edit5 if you have nished editing, or you can press 4Next5 or 4Prev5 to edit the other parameters. The second page of the printout has a listing of the values of the samples from the application.
