:READ:HARMonics:FUNDamental?
Syntax
:READ:HARMonics:FUNDamental?
Description
Executes one harmonic distortion measurement and returns the frequency of the fundamental waveform.
Remarks
This command has the same function as :READ:HARMonics:FREQuency? 1.
This command will select data from the latest measurement results, and then transmit the data to the
output buffer.
This command is only available for GPSA mode.
Return Format
The query returns the frequency of the fundamental waveform in scientific notation. The unit is Hz. For
example, 4.550000000e+07
:READ:OBWidth?
Syntax
:READ:OBWidth?
Description
Executes one occupied bandwidth measurement and returns the measurement results.
Remarks
This command will select data from the latest measurement results, and then transmit the data to the
output buffer.
This command is only available for GPSA mode.
Return Format
The query returns the occupied bandwidth (Hz) and the transmit frequency error (Hz) in scientific notation
(separated by commas).
For example, 1.860000000e+06,2.000000000e+04
