31 :WGEN Commands

:WGEN:MODulation:NOISe

(see page 790)

Command Syntax

:WGEN:MODulation:NOISe <percent>

<percent> ::= 0 to 100

The :WGEN:MODulation:NOISe command adds noise to the currently

selected signal. The sum of the amplitude between the original signal and

injected noise is limited to the regular amplitude limit (for example, 5 Vpp

in 1 MOhm), so the range for <percent> varies according to current

amplitude.

Note that adding noise affects edge triggering on the waveform generator

source as well as the waveform generator sync pulse output signal (which

can be sent to TRIG OUT). This is because the trigger comparator is

located after the noise source.

Query Syntax

:WGEN:MODulation:NOISe?

The :WGEN:MODulation:NOISe query returns the percent of added noise.

Return Format

<percent> ::= 0 to 100
