These commands take the instrument from its current state, enable the specified measurement and put the instrument into single sweep mode. They correct any parameters that are invalid given the new measurement state such that a valid measurement can take place. Other settings may be changed; see the documentation of CONFigure for each measurement. They then initiate the measurement. When the measurement is complete, they return the result.To make a measurement with settings other than the “default” measurement settings applied by CONFigure, do the following:Sets the active measurement to Constellation, sets the default measurement parameters, triggers a new measurement, and returns the EVM (rms), EVM (pk), RCE (rms), RCE (pk), Carrier Frequency, Freq Error, Freq Error, and the Base Station ID. It is a combination of the commands :CONFigure:DEMod CONStln; :READ:DEMod:CONStln? To make a Demodulated Constellation measurement with settings other than the default values send:Data is returned as 8 comma-delimited values: EVM (rms) in %, EVM (pk) in %, RCE (rms) in dB, RCE (pk) in dB, Freq Error in MHz, CINR in dB, Base Station ID, and the Sector ID.:READ:DEMod:CONStln?
:CONFigure:DEMod CONStlnSets the active measurement to EVM vs. Sub Carrier, sets the default measurement parameters, triggers a new measurement, and returns the EVM (rms), EVM (pk), RCE (rms), RCE (pk), Carrier Frequency, Freq Error, Freq Error, and the Base Station ID. It is a combination of the commands :CONFigure:DEMod EVSCarrier; :READ:DEMod:EVSCarrier? To make a EVM vs. Symbol measurement with settings other than the default values send:Data is returned as 8 comma-delimited values: EVM (rms) in %, EVM (pk) in %, RCE (rms) in dB, RCE (pk) in dB, Carrier Frequency in MHz, Freq Error in MHz, Freq Error in ppm, and the Base Station ID.:READ:DEMod:EVSCarrier?
:CONFigure:DEMod EVSCarrierSets the active measurement to EVM vs. Symbol, sets the default measurement parameters, triggers a new measurement, and returns the EVM (rms), EVM (pk), RCE (rms), RCE (pk), Carrier Frequency, Freq Error, Freq Error, and the Base Station ID. It is a combination of the commands :CONFigure:DEMod EVSYmbol; :READ:DEMod:EVSYmbol? To make a EVM vs. Symbol measurement with settings other than the default values send:Data is returned as 8 comma-delimited values: EVM (rms) in %, EVM (pk) in %, RCE (rms) in dB, RCE (pk) in dB, Carrier Frequency in MHz, Freq Error in MHz, Freq Error in ppm, and the Base Station ID.:READ:DEMod:EVSYmbol?
:CONFigure:DEMod EVSYmbolSets the active measurement to Spectral Flatness, sets the default measurement parameters, triggers a new measurement, and returns the absolute delta of the power between adjacent sub carriers in dB. It is a combination of the commands :CONFigure:DEMod SFLatness; :READ:DEMod:SFLatness? To make a Spectral Flatness measurement with settings other than the default values send::READ:DEMod:SFLatness?
:CONFigure:DEMod SFLatnessSets the active measurement to PASS/FAIL, sets the default measurement parameters, triggers a new measurement and returns the PASS/FAIL results. It is a combination of the commands :CONFigure:PFail; :READ:PFail? To make a channel power measurement with settings other than the default values send:Sets the active measurement to ACPR, sets the default measurement parameters, triggers a new measurement, and returns the power levels for each channel (both absolute and relative). It is a combination of the commands :CONFigure:RF ACPR; :READ:RF:SPECtrum? To make an RF ACPR measurement with settings other than the default values send:Data is returned as 11 comma-delimited values: The Channel Power in dBm, relative adjacent channel 1 power level, absolute adjacent channel 1 power level, relative adjacent channel 2 power level, absolute adjacent channel 2 power level, relative adjacent channel 3 power level, absolute adjacent channel 3 power level, relative adjacent channel 4 power level, absolute adjacent channel 4 power level, relative adjacent channel 5 power level, absolute adjacent channel 5 power level. The relative adjacent channel power level is in dB and the absolute adjacent channel power level is in dBm.Sets the active measurement to Power vs. Time, sets the default measurement parameters, triggers a new measurement and returns the Channel Power, Preamble power, burst power of data bursts, and the Crest Factor. It is a combination of the following commands CONFigure:RF PVTime; :READ:RF:PVTime? To make an RF ACPR measurement with settings other than the default values send:Data is returned as 4 comma-delimited values: The Channel Power in dBm, Preamble power in dBm, burst power of data bursts in dBm, and the Crest Factor in dB.:READ:RF:PVTime?
:CONFigure:RF PVTimeSets the active measurement to Spectrum, sets the default measurement parameters, triggers a new measurement and returns the Channel Power (RSSI) and Occupied bandwidth measurement. It is a combination of the following commands :CONFigure:RF SPECtrum; :READ:RF:SPECtrum? To make an RF Spectrum measurement with settings other than the default values send:Data is returned as 2 comma-delimited values: Channel Power (RSSI) in dBm Occupied bandwidth measurement in MHz.
