I/O Board The I/O board contains USB ports, Compact Flash port, an Ethernet connector, TekLink, XGA Video, and a Trigger Out port. Main Board The main board module contains the following functions: 2- 2 Acquisition System The acquisition system begins with the analog signal path and ends with a digitized signal in memory. The signal enters a channel input, and then passes through an attenuator and preamplifier. The analog signal from each preamplifier goes through a digitizer, a time base controller, and then into acquisition memory. The analog signal from each preamplifier is also distributed to a trigger circuit. Trigger System The trigger system processes the analog signals from the preamplifiers and sends trigger information to the time base controller. Advanced trigger functions are enabled only when the appropriate application modules and supporting software are installed. Display System The display system combines live waveform data from acquisition memory with menus and text and stores this information in display memory. It then uses this data to refresh the XGA display module (LCD). DPO4000 Series Service Manual Theory of Operation Processor System Power Converter The processor system contains a 440EP Power PC microprocessor that controls the entire instrument. The processor system also contains FLASH ROM, system RAM, and interfaces to USB ports and a Compact flash slot. The power converter receives +12V from the main power supply and generates voltages for the analog and digital circuitry on the main board. Front- Panel Board The front-panel board contains a microprocessor that reads the front-panel buttons and controls, and then sends this information to the processor system on the main board. The front-panel board also generates the probe compensation output signal and provides an interface to the application modules. DPO4000 Series Service Manual 2- 3 Theory of Operation 2- 4 DPO4000 Series Service Manual Adjustment Procedures Adjustment Procedures This chapter contains the factory adjustment procedures for the DPO4000 series oscilloscopes. Only qualified personnel should perform adjustment procedures. Read the Service Safety Summary and the General Safety Summary before performing any service procedures. NOTE. The voltage references inside the oscilloscope are very stable over time and should not require routine adjustment. Before performing any procedure in this chapter, do the Performance Verification procedures to check whether the oscilloscope meets specifications. See the DPO4000 Technical Reference. Successful completion of this adjustment procedure automatically updates the instrument Calibration Due date and time. (Completion of the Performance Verification procedure does not update the instrument Calibration Due date and time.) Required Equipment The following equipment, or a suitable equivalent, is required to complete these procedures. DPO4000 Series Service Manual Description Minimum requirements Example DC voltage source 50 mV to 70 V, ±0.1% amplitude accuracy Wavetek 9500 Oscilloscope Calibrator with one 9510 Output Module Sine Generator 1 GHz Edge Generator 1 kHz with <50 ps ch-- ch skew Wavetek 9500 with 9530 output t t modules d l 50 Ω BNC cable BNC male to BNC male, ≈ 10 in (25 cm) long Tektronix part number 012-0208-00 Adjustment tool Non conducting shaft with diameter ≤2.5 mm (≤0.1 in) Tektronix part number 003-1433-00 3- 1 Adjustment Procedures Overview of the Adjustment Process Before performing adjustment procedures, you must warm up the oscilloscope at least ten minutes in an ambient temperature between 20 °C and 30 °C. Adjustments performed before warm-up or outside this temperature range may result in poor performance. The factory adjustment procedure consists of a series of steps; as you move through these steps, the oscilloscope display provides instructions that describe the specific input signal requirements for each step. If the the oscilloscope passes the step, it moves on to the next step. If the oscilloscope fails, you can repeat the step or choose to abort the procedure. NOTE. Do not turn any knobs or push any front-panel buttons other than the Next Step or Previous Step buttons during the adjustment procedure. Doing so will cause the oscilloscope to abort the adjustment procedure. The oscilloscope uses the previous calibration constants if the adjustment procedure is aborted. The screen does not display the actual oscilloscope settings (such as channel input impedance or vertical and horizontal settings) during the adjustment procedure. The oscilloscope automatically sets the instrument settings, but these settings may not read out correctly on the display. During some steps, the instrument may appear to be idle for several minutes while it is processing information internally. If the oscilloscope completes all steps in the procedure successfully, a “Pass” message is displayed and the new calibration constants take effect. If the oscilloscope does not pass the procedure, the oscilloscope reverts to the previous calibration settings. 3- 2 DPO4000 Series Service Manual Adjustment Procedures Factory Adjustment Procedure To perform the factory adjustment procedure, do these steps: 1. Connect the oscilloscope to an AC power source. NOTE. You must connect the oscilloscope and the test equipment to the same AC power circuit. Connect the oscilloscope and test instruments to a common power strip if you are unsure of the AC power circuit distribution. Connecting the oscilloscope and test instruments to separate AC power circuits can result in offset voltages between the equipment, which can invalidate the adjustment procedure. 2. Locate the hole in the rear panel that provides access to the CAL switch on the rear panel. CAL 3. Insert the adjustment tool into the CAL switch hole. Use the tool to push and hold the CAL switch in while you power on the oscilloscope. Release the switch when the oscilloscope shows the power-on message with the oscilloscope graticule in the background. 4. Push the Default Setup button. NOTE. Do not skip the recall Default Setup step. You must recall the factory settings in order to correctly start the factory adjustment procedure. 5. Push the MENU OFF button. 6. Push the UTILITY button. 7. Push the System Config lower bezel button repeatedly to select Calibration. DPO4000 Series Service Manual 3- 3 Adjustment Procedures 8. Push the Factory lower bezel button. 9. Push the OK Do Factory Calibration side bezel button to start the adjustment process. 10. Connect signals from the DC voltage source as instructed by the oscilloscope display. After you connect the correct signal, push the OK Do Next Step side bezel button to continue the process. NOTE. The oscilloscope adjusts itself automatically using the reference signal from the DC voltage source. You do not need to make any adjustments. If you make an error, such as connecting the wrong input signal, you can repeat the last step by pushing the Return to Previous Screen side bezel button. 11. Continue with the adjustment process until it is complete. You can abort the process at any time by pushing the MENU OFF button. 12. Do the performance verification tests to verify that the adjustment procedure has correctly calibrated the oscilloscope. (See the DPO4000 Technical Reference.) Incorrect use of calibration equipment can cause the oscilloscope to pass the adjustment procedure but fail performance verification. 3- 4 DPO4000 Series Service Manual Maintenance Maintenance This section contains the information needed to do periodic and corrective maintenance on the oscilloscope as well as repackaging instructions if you need to return the oscilloscope to Tektronix for service.
