Arb Commands
Dual ARB Subsystem–N5172B/82B ([:SOURce]:RADio:ARB)
[:SOURce]:RADio:ARB:RSCaling <value>
[:SOURce]:RADio:ARB:RSCaling?
This command adjusts the scaling value in percent that is applied to a waveform while it is playing.
The variable
<value>
is expressed as a percentage. Runtime scaling does not alter the waveform data
file. This feature is used to avoid DAC overflow. The scaling is compensated for at the modulator (i.e.
when the modulator is the optimized path). For more information about runtime scaling, refer to the
User’s Guide
.
Example
:RAD:ARB:RSC 50
The preceding example applies a 50% scaling factor to the selected waveform. Runtime scaling does
not alter the waveform data file.

Key Entry
Runtime Scaling
Remarks
Saving the instrument state saves the currently- set Runtime Scaling in the
instrument state file.
:SCALing
Supported
N5172B/82B
[:SOURce]:RADio:ARB:SCALing "<file_name>",<value>
This command scales the designated
"<file_name>"
waveform file while it is being played by the
dual ARB player. The variable
<value>
is expressed as a percentage, 1–100%. The peak value of the
waveform is disconnected and the whole waveform is scaled such that the peak value is at the
specified percentage of full scale.
Unlike runtime scaling (:RSCaling), Scaling (:SCALing) has a permanent effect on the waveform data.
Scaling up, after scaling down, typically results in a slightly different waveform from the original, as
some data is lost in the scale–down process. For more information about waveform file scaling, refer
to the
User’s Guide
.
Example
:RAD:ARB:SCAL "Test_Data", 50
The preceding example applies a 50% scaling factor to the Test_Data waveform file.
Range
1 to 100 percent
Remarks
