Arb Commands
Dual ARB Subsystem–N5172B/82B ([:SOURce]:RADio:ARB)
Examples
[:SOURce]:RADio:ARB:HEADER:RMS "WFM1:Sine_Wave",.835
The first example shows a user–measured RMS value for the Sine_Wave waveform file in the
waveform’s file header.
:RAD:ARB:HEADER:RMS "WFM1:Sine_Wave",UNSP
In the second example, the signal generator calculates the RMS value when the ARB is turned on
with this file selected or a sequence which contains the file selected.
The RMS value is expressed in volts.
Range 0 to 1.414213562373095
:HEADer:SAVE
Supported N5172B/82B
[:SOURce]:RADio:ARB:HEADer:SAVE
This command saves the Dual ARB state information to the header of the currently selected
waveform.
Key Entry Save Setup To Header
Remarks A waveform must be selected for this command to function.
:IQ:MODulation:ATTen
Supported N5172B/82B
[:SOURce]:RADio:ARB:IQ:MODulation:ATTen <value>
[:SOURce]:RADio:ARB:IQ:MODulation:ATTen?
This command sets the attenuation level of the I/Q signals being modulated through the signal
generator RF path.
The variable <value> is expressed in units of decibels (dB).
*RST Varies (instrument dependent)
Range 0 to 50
Key Entry Modulator Atten Manual Auto
:IQ:MODulation:ATTen:AUTO
Supported N5172B/82B
[:SOURce]:RADio:ARB:IQ:MODulation:ATTen:AUTO ON|OFF|1|0
[:SOURce]:RADio:ARB:IQ:MODulation:ATTen:AUTO?
This command enables or disables the I/Q attenuation auto mode.
ON (1) This choice enables the attenuation auto mode which optimizes the modulator
attenuation for the current conditions.
