NOISe indicates that the internal noise is added to the output signal.
"" disables the internal noise add function.
"NOIS"
SOURce1:COMBine:FEED "NOIS"
adds a noise signal to the CH 1 output signal.
This command sets or queries the peak frequency deviation of FM modulation for
the specified channel. The setting range of frequency deviation depends on the
waveform selected as the carrier. For more information, refer to the AFG2021
instrument Specifications and Performance Verification Manual.

<deviation>::=<NRf>[<units>]
where:
<NRf> is the frequency deviation.
<units>::=[Hz | kHz | MHz]
<deviation>
SOURce1:FM:DEViation 1.0MHz
sets the CH 1 frequency deviation to 1.0 MHz.
This command sets or queries the internal modulation frequency of FM
modulation for the specified channel. You can use this command only when the
internal modulation source is selected.
