FM:FREQuency<fm_freq>(?)
Description
This command will set the modulating wave frequency for the built-in standard modulating waveform library.
Parameters
Name Range Type Default Description
<fm_freq> 10e-3 to
100e3 Numeric 10e3 Programs the frequency of the modulating waveform
in units of Hz. The frequency of the built-in standard
modulating waveforms only is affected.
Response
The 5251 will return the present modulating waveform frequency value. The returned value will be in
standard scientific format (for example: 100mHz would be returned as 100e-3 – positive numbers are
unsigned).
FM:FREQuency:RASTer<arb_fm_freq>(?)
Description
This command will set the sample clock frequency for the arbitrary modulating waveform. Arbitrary
modulating waveforms must be created in an external utility and downloaded to the FM arbitrary waveform
memory before this function can be used.
Parameters
Name Range Type Default Description
<arb_fm_freq
> 1 to
2.5e6 Numeric 1e6 Programs the sample clock frequency of the arbitrary
modulating waveform in units of S/s.
Response
The 5251 will return the present sample clock of the arbitrary modulating waveform value. The returned
value will be in standard scientific format (for example: 100mHz would be returned as 100e-3 – positive
numbers are unsigned).
