UI Parameter:Link Type
Description
Displays the link type. For the current version, it is UplinGk only.
The software provides a standard SCPI list created for this software that typically provides the same functionality as the GUI. This list also provides links to the command descriptions.
These commands have no corresponding UI Parameters, but set the real-time baseband for instruments loaded with Signal Studio for LTE/LTE-Advanced FDD (N7624C).
Use this topic to find SCPI commands that do not have corresponding UI parameters supported by either of the N5172B EXG or the N5182B MXG vector signal generators.
These commands set the real-time baseband and LTE FDD functionality.

[:SOURce]:RADio:LTE:FDD[:BBG]:LINK?
UI Parameter:Link Type
Displays the link type. For the current version, it is UplinGk only.
[:SOURce]:RADioLTE:FDD[:BBG]:POWer:ORMS?
UI Parameter: Unscaled Output Power
This query returns the output RMS power when USER is selected for the source of the power measurement.
[:SOURce]:RADioLTE:FDD[:BBG]:POWer:PMGating THReshold|MARKers
[:SOURce]:RADioLTE:FDD[:BBG]:POWer:PMGating?
UI Parameter: Power Meter Gating
This command sets the reference to be used for power meter gating.
THReshold
This choice selects the threshold as the reference for power meter gating. Power observations are only accumulated if they are greater than or equal to the specified threshold, or if the number of consecutive observations below the threshold has not exceeded the hold-off sample count value.
MARKers
This choice uses the marked samples as the reference for power meter gating. Power observations are only accumulated for marked samples according to the specified marker selection. When the marker is turned on, the voltage for the waveform sample is used to determine the waveform RMS value. The marker control criteria is configured using the marker commands.
[:SOURce]:RADio:LTE:FDD[:BBG]:POWer:SAVerage <val>
[:SOURce]:RADio:LTE:FDD[:BBG]:POWer:SAVerage?
UI Parameter: Samples to Average
This command sets the number of samples to average when calculating the RMS voltage when the power source is Measure. The value entered is rounded to the nearest power of 2. When the waveform is measured during the signal creation, the instrument measures the specified number of samples that meet the criteria set by the threshold or marker settings and then uses these sample RMS voltage values to calculate the mean RMS voltage for the subsequent power calibration. Ensure that the number of samples is equal to or greater than the part of the waveform that you want to measure.
Range: 4 to 2^39 - 1 (4 to 549755813887)
[:SOURce]:CONTrol:RADio:LTE:FDD[:BBG]:POWer:SOURce MEASure|APRovided
[:SOURce]:CONTrol:RADio:LTE:FDD[:BBG]:POWer:SOURce?
UI Parameter: Input RMS Source
This command selects the method to use for calculating the RMS voltage value of the waveform to ensure the correct amplitude of the waveform at the output of the signal generator. The RMS voltage is used to calculate the power of the system when the power calibration is performed.
MEASure
This choice selects an internal power meter calculation to measure the input RMS power level. When Measure is selected, the power meter gating can be set to use a voltage threshold value or a marker to identify the portions of the waveform that will be measured.
APRovided
This choice selects an application calculated value to input the RMS value.
