![Chapter 1 Safety Instructions2098.1190.72 - 1.1 - E-41 About this ManualThis manual is part of the documentation for the NX8000 family of transmitters from Rohde& Schwarz. Each transmitter and each transmitter component is described in a separatemanual. The individual manuals of the family of transmitters are modular in structure andcomplement each other. StructureEach transmitter component is described in a separate manual and can thus be used as anindividual component (where practical). The transmitter manual is the main document forthe entire set of documentation. It describes all steps that are necessary to install a trans-mitter, put it into operation, operate and maintain it. Where applicable, the transmitter man-ual refers to the individual manuals for the various components. The component manuals,in turn, also refer to the transmitter manual whenever the component is to be used as atransmitter module.ContentsThe manuals for the family of transmitters describe all steps required to install the transmit-ter or one of its components, put them into operation, operate and maintain them, trouble-shoot and service them. The Annex includes interface descriptions plus technicaldocuments. For convenience, all manuals are structured identically. Sections that are not relevant to themanual at hand are also included but are left blank. SafetyAll skilled personnel working with a transmitter or its components must read all relevantmanuals and comply with the safety measures that are detailed in the chapter about safetyand in the applicable sections in the manual. The transmitter and the individual transmittercomponents must be used only for their intended purpose. All operations involving thetransmitter or individual transmitter components must be performed by skilled personnel.The manual will point out specifically if additional qualifications are required. Symbols and LayoutThe triangular warning symbol indicates danger. In addition to the triangular warning sym-bol, different key words indicate the level of potential danger.Instructions are given in numbered steps or indicated by an "index finger" symbol to the leftof the instruction text.

![Basic Safety Instructions 1171.0000.42-05.00 Page 3 Electrical safety If the information on electrical safety is not observed either at all to the extent necessary, electric shock, fire and/or serious personal injury or death may occur. 1. Prior to switching on the product, always ensure that the nominal voltage setting on the product matches the nominal voltage of the AC supply network. If a different voltage is to be set, the power fuse of the product may have to be changed accordingly. 2. In the case of products of safety class I with movable power cord and connector, operation is permitted only on sockets with an earthing contact and protective earth connection. 3. Intentionally breaking the protective earth connection either in the feed line or in the product itself is not permitted. Doing so can result in the danger of an electric shock from the product. If extension cords or connector strips are implemented, they must be checked on a regular basis to ensure that they are safe to use. 4. If the product does not have a power switch for disconnection from the AC supply network, the plug of the connecting cable is regarded as the disconnecting device. In such cases, always ensure that the power plug is easily reachable and accessible at all times (corresponding to the length of connecting cable, approx. 2 m). Functional or electronic switches are not suitable for providing disconnection from the AC supply network. If products without power switches are integrated into racks or systems, a disconnecting device must be provided at the system level. 5. Never use the product if the power cable is damaged. Check the power cable on a regular basis to ensure that it is in proper operating condition. By taking appropriate safety measures and carefully laying the power cable, you can ensure that the cable will not be damaged and that no one can be hurt by, for example, tripping over the cable or suffering an electric shock. 6. The product may be operated only from TN/TT supply networks fused with max. 16 A (higher fuse only after consulting with the Rohde & Schwarz group of companies). 7. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and all the way into the socket. Otherwise, sparks that result in fire and/or injuries may occur. 8. Do not overload any sockets, extension cords or connector strips; doing so can cause fire or electric shocks. 9. For measurements in circuits with voltages Vrms > 30 V, suitable measures (e.g. appropriate measuring equipment, fusing, current limiting, electrical separation, insulation) should be taken to avoid any hazards. 10. Ensure that the connections with information technology equipment, e.g. PCs or other industrial computers, comply with the IEC60950-1/EN60950-1 or IEC61010-1/EN 61010-1 standards that apply in each case. 11. Unless expressly permitted, never remove the cover or any part of the housing while the product is in operation. Doing so will expose circuits and components and can lead to injuries, fire or damage to the product. 12. If a product is to be permanently installed, the connection between the PE terminal on site and the product's PE conductor must be made first before any other connection is made. The product may be installed and connected only by a licensed electrician. 13. For permanently installed equipment without built-in fuses, circuit breakers or similar protective devices, the supply circuit must be fused in such a way that anyone who has access to the product, as well as the product itself, is adequately protected from injury or damage.](https://usermanual.wiki/Rohde-and-Schwarz/NV830X.User-Manual-Part-1/User-Guide-1672826-Page-32.png)
![Basic Safety Instructions 1171.0000.42-05.00 Page 4 14. Use suitable overvoltage protection to ensure that no overvoltage (such as that caused by a bolt of lightning) can reach the product. Otherwise, the person operating the product will be exposed to the danger of an electric shock. 15. Any object that is not designed to be placed in the openings of the housing must not be used for this purpose. Doing so can cause short circuits inside the product and/or electric shocks, fire or injuries. 16. Unless specified otherwise, products are not liquid-proof (see also section "Operating states and operating positions", item 1. Therefore, the equipment must be protected against penetration by liquids. If the necessary precautions are not taken, the user may suffer electric shock or the product itself may be damaged, which can also lead to personal injury. 17. Never use the product under conditions in which condensation has formed or can form in or on the product, e.g. if the product has been moved from a cold to a warm environment. Penetration by water increases the risk of electric shock. 18. Prior to cleaning the product, disconnect it completely from the power supply (e.g. AC supply network or battery). Use a soft, non-linting cloth to clean the product. Never use chemical cleaning agents such as alcohol, acetone or diluents for cellulose lacquers. Operation 1. Operating the products requires special training and intense concentration. Make sure that persons who use the products are physically, mentally and emotionally fit enough to do so; otherwise, injuries or material damage may occur. It is the responsibility of the employer/operator to select suitable personnel for operating the products. 2. Before you move or transport the product, read and observe the section titled "Transport". 3. As with all industrially manufactured goods, the use of substances that induce an allergic reaction (allergens) such as nickel cannot be generally excluded.

![Chapter 1 Safety Instructions2098.1190.72 - 1.4 - E-44 Special Danger Warnings4.1 Hazards due to AC Supply VoltageThere is a risk of electric shock with any Vrms > 30 V AC or V > 60 V DC voltage. Appropri-ate measures must be taken to prevent exposure to any danger when working with voltagesthat bear the risk of electric shock. Never work on live parts unless specifically required andonly if the special safety precautions are complied with.4.1.1 AC Power SupplyBefore connecting the AC power supply, it is important to ensure that the power supplyspecifications given for the system or instruments match the nominal specifications forthe local power supply network. The power supply circuit must be protected by meansof fuses in order to prevent overloads and short-circuits.Miniature modules have neutral conductor fuses. As a result, the power supply may stillbe connected even after interruption of the circuit by a fuse. It is quite possible for a transmitter to have several separate electric circuits. Each of thesecircuits is subject to the following requirements:All electrical connections between the transmitter and the AC power supply must complywith the following conditions:– The transmitter can be disconnected at any time.– The transmitter can be prevented from being switched back on.– The transmitter is terminated with a fully protected power cable matched to the powerconsumption.1– Ensure that phase rotation is correct (direction of rotation of fans!).Service socketsIt is common practice to equip transmitters with a connector that carries voltage even whenthe transmitter is turned off and that allows power to be supplied to test equipment or a sol-dering iron. These connectors are identified, e.g. by an LED, and may only be used for theaforementioned purposes. The intended purpose of the sockets means that they have only a limited power output. Theconnector is not suitable for supplying power to heating equipment or large test sets.The transmitter operator is responsible for providing the correct fuse protection (themaximum value is specified on the socket).In the case of accessory parts that are not connected to the main transmitter, the trans-mitter operator is responsible for taking appropriate measures to ensure that the instal-lation is safe in the respective switching state.1 Obtain the specifications from this documentation and also adhere to the breaking capacity limits of the fusesand circuit breakers in the transmitter.](https://usermanual.wiki/Rohde-and-Schwarz/NV830X.User-Manual-Part-1/User-Guide-1672826-Page-42.png)
![Chapter 1 Safety Instructions2098.1190.72 - 1.5 - E-44.1.2 Replacing FusesReplace the safety fuses accessible in the operator area only if no voltage is being ap-plied to the instruments. The safety fuses may be replaced only by fuses with identicalelectric data, identical switching characteristics and identical switch-off capacity.Motor and line circuit breakers accessible in the transmitter's operator area may be op-erated. If their response range is selectable, do not change the settings made by themanufacturer. If the settings are accidentally changed, reset them by using the correctvalues specified in this documentation.4.1.3 Emergency-Off EquipmentIf the customer requests, the transmitters are equipped with emergency keys. When thetransmitters are supplied, these keys have basically no function. The transmitter opera-tor is responsible for ensuring that these emergency keys function safely and to inte-grate them into the emergency-off system of the operator area in accordance with theregulations. If you subsequently decide not to use the emergency keys as an emergen-cy-off system, you must remove them. Extremely important! A transmitter normally has several AC supply circuits that areindependent from each other, such as main AC supply circuit, AC current supply for ac-cessory equipment (main control unit, antenna switch, etc) or AC current supply for adisabled socket. The transmitter operator is responsible for making sure that all these circuits are inte-grated correctly into the emergency-off system. Circuits not integrated have to be la-beled accordingly.Never set up a transmitter that is equipped with disabled emergency-off equipment.4.1.4 Opening the TransmitterWhen you open the transmitter to carry out mechanical/electrical tasks (e.g. cleaning,repair, etc) always follow the five basic rules for working with electrical systems:– Disconnect the transmitter from the power supply– Secure it against inadvertent switch-on– Verify safe isolation from any power– Ground or short-circuit it2– Cover adjacent active circuits.Extremely important! A transmitter normally has several AC supply circuits that are in-dependent from each other, such as main AC supply circuit, AC current supply for ac-cessory equipment (main control unit, antenna switch, etc) or AC current supply for adisabled socket. Prior to performing any work, check the current status of the circuits. Also disconnectadjacent circuits to prevent inadvertent contact.2 Not all transmitter types can be grounded or short-circuited by using a grounding or short-circuit switch. If asuitable device for grounding or short-circuiting is not available, the skilled personnel must take appropriatemeasures as deemed necessary.](https://usermanual.wiki/Rohde-and-Schwarz/NV830X.User-Manual-Part-1/User-Guide-1672826-Page-43.png)
![Chapter 1 Safety Instructions2098.1190.72 - 1.6 - E-4If you have to perform any work on the RF circuit, isolate the antenna connector as well. Caution! If other transmitters, etc, are in operation that are coupled to the same antennavia RF filters, energy from them can be fed back via the antenna cable.Never open a disconnected transmitter without taking protective measures againsttouching voltage-carrying parts.Due to the risk of electric shock from the AC supply voltage, never perform any electricaloperations when doors are open, front panels are unscrewed, plug-ins are withdrawn,etc. When electrical operations of the transmitter are performed for the purpose of internalmeasurements or repair, label the workplace accordingly and provide warning about thepotential hazards in accordance with the basic rules of electrical engineering. Appropriate measures have to be taken to prevent unauthorized persons from access-ing this area. After completing your work, close the transmitter and restore all safety measures for pre-venting electric shock that have been provided by the manufacturer. Immediately makesure that protective equipment (e.g. locks) is effective.4.2 Hazards due to High-Energy CircuitsThe instruments include low-voltage circuits which can be fed from an extremely low-imped-ance voltage source(e.g. amplifier operating voltage). These circuits conduct dangerouslylarge amounts of energy. We handle these circuits in the same manner as circuits with volt-ages that bear the risk of electric shock. They are usually covered and thus protectedagainst accidental contact. The cover comes with a warning label.If you remove the cover of a transmitter that is in operation, there is the risk of both voltagepoles being short-circuited. Short circuits create an electric arc and thus can cause burns,damage to the eyes as well as further injuries due to the state of shock response.Practical experience has repeatedly shown that a short circuit caused by metal tools cancause severe burns. For safety reasons, high-energy circuits are protected by covers andare thus not accessible within the operator area of the instruments.If you need to measure low-impedance voltages, during repair work or to optimize thepower consumption of the transmitter for example, exercise the same caution as whenmeasuring operating voltages that bear the risk of electric shock.Wear protective clothing if necessary.Before you open an instrument or remove its cover, switch off the operating voltage andwait for five minutes to ensure that any and all capacitors are sufficiently discharged.Do not short-ciruit capacitors to discharge them.4.3 RF Hazards4.3.1 Mandatory TrainingOperators must instruct their personnel on how to use this transmitter or instrument inaccordance with EN 60215 and IEC 215. This periodic training must cover the radio-fre-](https://usermanual.wiki/Rohde-and-Schwarz/NV830X.User-Manual-Part-1/User-Guide-1672826-Page-44.png)
![Chapter 1 Safety Instructions2098.1190.72 - 1.7 - E-4quency hazards of the individual transmitter or instrument. Only after such training hasbeen provided and documented may the operating personnel handle switching and op-erating tasks.High-energy RF circuits within the transmitter or the instrument are routed via conventionaldetachable RF connectors (e.g. N). Depending on the output power, the transmitter or in-strument outputs come with screw-in or pluggable RF lines or ducts.If RF lines or modules conduct high power, the connection point or the entire module ismarked with the standard warning symbol (yellow triangle with black exclamation mark).4.3.2 RF ShieldingTransmitters and instruments from Rohde & Schwarz are shielded in such a manner thatRF radiation does not pose any danger even in the immediate vicinity if all RF lines areclosed. This statement is based on the ordinance for electromagnetic fields as defined inGerman law: The 26th ordinance for the Federal Emission Protection Law dated December 16, 1996 de-fines limit values for radio-frequency equipment for electric and magnetic field strengths. 4.3.3 Rules for Operating the TransmitterOpening RF lines during operation may cause electric arcs. This can cause burns and eyeinjuries.Operate the transmitter system only if an antenna or dummy antenna is connected.Never undo RF lines during transmitter operation.Never open modules during transmitter operation.Never put transmitters into operation if RF lines are open. 3When disconnecting a transmitter, always disconnect the antenna connector as well. Ifother transmitters, etc, are in operation that are coupled to the same antenna via RF fil-ters, energy from them can be fed back via the antenna cable.4.3.4 Rules for Working with an Open TransmitterIf you switch on an open transmitter and remove covers and shielding that carry the generalwarning symbol of RF modules, dangerous RF levels will be radiated .The transmitter operator is responsible for strict compliance with the necessary safety pre-cautions when someone is working with or located near an open transmitter that is switchedon. Necessary safety regulations include:3 If you try to put the transmitter into operation, RF power is transmitted. If RF lines are open, the transmitterswitches off the RF again. This attempt to transmit RF can lead to the above mentioned risks of injury even if- as is the case with Rohde & Schwarz transmitters - the RF flow is limited and transient due to technical mea-sures.](https://usermanual.wiki/Rohde-and-Schwarz/NV830X.User-Manual-Part-1/User-Guide-1672826-Page-45.png)

This also applies to radio transmitters. For transmitter radio systems, it is thereforenecessary to create a safety plan for the event of fire. Operating personnel must be trained on how to proceed in the case of fire in areas contain-ing electrical systems; training must be repeated at regular intervals. Personnel should betrained on the basis of the VDE 0132 standard and in agreement with the local fire depart-ment. The following statement applies in Germany. Preventive measures at the site in questioncan largely eliminate the risk of fire or prevent its spread as far as possible.Prevention and fire-fightingWhen setting up the transmitter, the operator must ensure that no inflammable materialsare located below or above the cable entry nor attached to it. Make sure that openings to adjacent spaces are closed in a flame-retardant manner.Fire-fighting is only allowed with special equipment even if the flames are insignificantor have no effect at all (e.g. breathing mask with air bottle).For fire-fighting, only suitable fire extinguishers (e.g. CO2 extinguishers) may be used.One reason for requiring special equipment is the fact that extremely poisonous and imper-ceptible carbon monoxide is released during every fire. Another reason is that the materialscontained in the instruments and systems emit poisonous vapors, gases and dust such assulfuric acid and hydrogen sulfide, hydrochloric acid, dioxin, hydrofluoric acid and berylliumoxide dust when they are exposed to external flame and heat. The following materials can be affected:– Rubber in cables, cable bushings, vibration absorbers and instrument feet– PVC in cables and lines– PUR (foam) in insulators, molded parts, sealing mats and insulating strips– Teflon in cables, lines, insulation material and printed boards – Beryllium oxide ceramics in power transistors](https://usermanual.wiki/Rohde-and-Schwarz/NV830X.User-Manual-Part-1/User-Guide-1672826-Page-46.png)

![Chapter 4 Commissioning2098.0188.72 - 4.31 - E-14 PrecorrectionThis section describes the non-linear precorrection sequence in manual mode.4.1 Functions of Nonlinear Precorrector4.1.1 GeneralIn the basic version, the graphical user interface of the non-linear precorrector for DTV andvideo signals consists of the Nonlinear control panel and the FreqCorrection control pan-el. In the case of ATV split, two further control panels are provided: Dynamic Control forthe video precorrector and Nonlinear Audio for the audio signal. In combined mode an au-dio phase precorrector is also provided for audio.4.1.2 Linear Basic PrecorrectionThe basic functions of the non-linear precorrector can be accessed via the Nonlinear andNonlinear Audio control panels. Additional functions can be performed in the other controlpanels.Every non-linear precorrector consists of an amplitude precorrector and a phase precorrec-tor, each independently affecting the phase distortion and amplitude distortion of the samesignal. The setting of the characteristic is displayed in a graphic in which the X axis repre-sents the instantaneous signal amplitude. The figures 0% and 100% stand for no signal am-plitude and maximum amplitude respectively. The Y axis represent the effect and is scaledto ±50 % for amplitude precorrection and ±45° for phase precorrection. 50% means that at100% amplitude the level is increased by 3 dB.Every precorrector has a series of frequency reference points which are used to model thecharacteristic. Frequency reference points can be user-defined, shifted in the X and Y di-rections, be given a fixed or free slope and be deleted. In the X direction a frequency refer-ence point can only be shifted between the two adjacent reference points. The connectionsbetween frequency reference points are computed by means of spline functions.Every characteristic consists of at least two points, one of which must be at 0% and the oth-er at 100%.In the case of amplitude precorrection the first point is at [0%, 0%] and cannot be shifted.The second point is at 100% and can be shifted without restriction in the Y direction. A risingor falling straight line between the two points represents only an amplification or attenuationof the signal and does not create non-linear products.In the case of phase precorrection the first point is at 0% and the second point is at 100%.Both points can be shifted without restriction in the Y direction. A straight line parallel to theamplitude axis creates only a signal phase shift and does not create non-linear products.](https://usermanual.wiki/Rohde-and-Schwarz/NV830X.User-Manual-Part-1/User-Guide-1672826-Page-149.png)
![Chapter 4 Commissioning2098.0188.72 - 4.32 - E-14.1.3 Nonlinear Frequency ResponsesAs an additional function, the non-linear components of the DTV/video precorrection (am-plitude or phase precorrection) can be assigned a frequency response in the FreqCorrec-tion control panel, and the effect of the frequency response depends on the modulation.If the amplitude precorrection or phase precorrection is affected by an amplitude frequencyresponse, only the "individual" precorrection is affected. Amplitude precorrection and phaseprecorrection have no influence on one another.If the amplitude precorrection or phase precorrection is affected by a phase frequency re-sponse, part of the "individual" precorrection affects the other precorrection. The amplitudeprecorrection and phase precorrection therefore have an influence on one another.4.1.4 Dynamic Precorrection (ATV Split Only)In ATV split systems, the large fluctuations in the average value of the video signal bringsabout temperature changes in the output-stage transistor which lead to changes in the out-put stage characteristic as a function of the average value of the modulation. This error canbe compensated for by dynamically modifying the characteristic as a function of the aver-age signal value.4.1.5 Audio Phase Precorrection (ATV Combined Only)In ATV combined systems, the common amplification of video and audio causes the audiosignal to be affected by the video signal. This effect can be minimized with the aid of anaudio phase precorrector.4.2 General Information on Operating PrecorrectorThe precorrector is operated by means of a web browser. The R&S NetCCU800 or exciterprovides a JAVA applet which is launched by the web browser. This applet contains all ofthe elements needed to operate the precorrector.Note Detailed information on operating the precorrector and configuring the graphical user inter-face can be found in the chapter "Operation" of the exciter manual.4.3 Performing PrecorrectionThe objective of precorrection is for the precorrector to simulate the non-linear characteris-tic of the amplifier as accurately as possible in order to increase the linearity of the outputsignal.However, the precorrection limit is tied to the overload capacity of the output stage. To ob-tain the greatest possible efficiency and lowest possible costs for a given transmitter, theoutput stages are set so as to achieve a transmitter output signal of the required quality.](https://usermanual.wiki/Rohde-and-Schwarz/NV830X.User-Manual-Part-1/User-Guide-1672826-Page-150.png)
![Chapter 4 Commissioning2098.0188.72 - 4.33 - E-14.3.1 General RequirementsThe following requirements should be fulfilled prior to precorrection:The transmitter must be operated at its nominal power output and the system level mustbe adjusted at all points.Precorrection must be on, for which the Nonlinear control panel must be selected in theprecorrector graphical interface. A precorrection curve consisting of a straight line posi-tioned on the X axis must be set for the amplitude precorrection and another for thephase precorrection.4.3.2 Determining System LevelsThe graphical area contains lines representing distinctive signal levels such as all-white lev-el (Wht), all-black level (Blk) and sync pulse level (Sync), as well as sync pulse level (Sync/Aud) in the case of ATV combined. In DVT the level lines indicate the peak level (Peak) andthe average value (Avh). These marks indicate maximum level; the actual level may be dif-ferent.Changes to the set curve that affect only the range above the system level have no effecton the signal or on precorrection of the signal. The following method can be used to determine the actual values:1. Use two interpolation points to determine the ends of the effective dynamic range in or-der to define the possible setting range of the precorrector:a) Add two interpolation points to the amplitude precorrection graph in the area abovethe highest mark and set their slope.You now have four points, consecutively numbered 1 to 4 from left to right. Points 2and 3 are each indicated by an arrow.b) Shift points 3 and 4 in the positive Y direction by +50%. Point 3 should then be im-mediately adjacent to point 2.c) Use the Write button to write this curve to the precorrector.2. Now use the Navigator window to reduce the position of interpolation points 2 and 3 to-gether in steps of one percent. Observe the effect:3. Restore the original status.ATV Split In ATV split systems, the first effect is seen in the sync pulse length, which can be clearly observed on the TV demodulator (sync pulse length dis-play) or the TV analyzer.ATV Combined In ATV combined systems, the first effect is seen in the intermodulation products about the two sound carriers fTx ± default f(T2-T1)DTV In DTV systems the effect is seen as a reduced shoulder distanceThe upper of the two interpolation points thus represents the determined dynamic range limit.](https://usermanual.wiki/Rohde-and-Schwarz/NV830X.User-Manual-Part-1/User-Guide-1672826-Page-151.png)

Note A measurement should be taken upstream of the output filter as the shoulders are difficultto detect owing to the band limiting of the filter. When measuring signals using the spectrumanalyzer, it is important to ensure that the precorrection target (e.g. 38 dB shoulder dis-tance) is well above the noise limit, but the frequency range of the spectrum analyzer issuch that no intermodulation is generated in its input section. Precorrection must be activated. In the graphics area for the amplitude and phase pre-correction, two interpolation points are present in each graph: the first point is modula-tion 0% with magnitude 0% or 0°, and the second point is modulation 100% withmagnitude 0% or 0°.A DTV spectrum with clear shoulders should be visible on the analyzer.](https://usermanual.wiki/Rohde-and-Schwarz/NV830X.User-Manual-Part-1/User-Guide-1672826-Page-152.png)

Since phase precorrection and amplitude precorrection affect one another, repeat bothprecorrection procedures if necessary until the optimum result is obtained. 4.3.3.2 Phase PrecorrectionProceed as follows for phase precorrection:1. Add in a phase reference point at about 10%.This position corresponds to a lower modulation of the amplifier.2. Shift the magnitude of the interpolation point for 100% up or down in steps of 0.5 orsmaller (+ or -) until the shoulder distance on the analyzer visibly improves.3. Keep improving the shoulder distance on the analyzer until the optimum result is ob-tained.4. Set another point at about 35%.5. Shift the magnitude of the interpolation point for 10% up or down in steps of ±0.5 orsmaller until the shoulder distance on the analyzer visibly improves. 6. Keep shifting the magnitudes of interpolation points 2 (10%), 3 (35%) and 4 (100%) insmall steps until the optimum result is obtained. Note Further interpolation points can be added for an optimum precorrection. The recommendednumber is four to a maximum of six interpolation points (including the interpolation points at0% and 100%). If phase precorrection gives no improvement or only a minor one, the phase precorrectionmust be canceled and amplitude precorrection must be carried out first.123 3](https://usermanual.wiki/Rohde-and-Schwarz/NV830X.User-Manual-Part-1/User-Guide-1672826-Page-153.png)

If the first interpolation point brings about an improvement, deal similarly with the other in-terpolation points.1. Set the interpolation points more or less at the positions of the phase values.2. Set all magnitudes to zero.3.

Keep carrying out phase precorrection and amplitude precorrection alternately until no fur-ther improvement can be obtained. Note Further interpolation points can be added for an optimum precorrection. The recommendednumber is four to a maximum of six interpolation points (including the interpolation points at0% and 100%). 4.3.3.4 Frequency-Dependent PrecorrectionBackgroundThe FreqCorrection control panel can be used to influence the characteristic by means ofan amplitude and/or phase frequency response, the effect of which is dependent on the lev-el.A set frequency response is applied to all signal components having a level greater thanthe selected threshold. On the other hand lesser signal components are unaffected.An amplitude frequency response (Amplitude Slope Amplitude 1/2 or Amplitude SlopePhase 1/2) and a phase frequency response (Phase Slope Amplitude 1/2 or Phase SlopePhase 1/2) can be applied to the amplitude characteristic and the phase characteristic in-dependently of one another. Two independent thresholds are available (Position Point 1or Position Point 2). The position of the thresholds (1 or 2) and their effect (A or P) aresymbolically represented in the graphic.](https://usermanual.wiki/Rohde-and-Schwarz/NV830X.User-Manual-Part-1/User-Guide-1672826-Page-155.png)

The range with the greatest effect can be determined by slightly chang-ing individual interpolation points.
