Arb Commands
Multitone Subsystem–N5172B/82B ([:SOURce]:RADio:MTONe:ARB)
When the Baseband Frequency Offset is non–zero, the hardware rotator accumulates phase–shift of
the baseband signal. This residual phase remains even after the offset value is returned to zero.
While there is a non–zero residual phase present in the signal, the DAC Over–Range Protection
feature will automatically prevent DAC overrange errors from occurring by scaling the signal down by
1/square root of 2.
:HEADer:CLEar
Supported N5172B/82B
[:SOURce]:RADio:MTONe:ARB:HEADer:CLEar
This command clears the header information from the file header used by this modulation format.
Key Entry Clear Header
Remarks The Multitone Off On softkey must be set to On for this command to function.
:HEADer:SAVE
Supported N5172B/82B
[:SOURce]:RADio:MTONe:ARB:HEADer:SAVE
This command saves the header information to the file header used by this modulation format.
Key Entry Save Setup To Header
Remarks The Multitone Off On softkey must be set to On for this command to function.
:IQ:MODulation:ATTen
Supported N5172B/82B
[:SOURce]:RADio:MTONe:ARB:IQ:MODulation:ATTen <val>
[:SOURce]:RADio:MTONe:ARB:IQ:MODulation:ATTen?
This command attenuates the I/Q signals being modulated through the signal generator RF path.
The variable <val> is expressed in units of decibels (dB).
