:WGEN<w> Commands 35
Keysight InfiniiVision 4000 X-Series Oscilloscopes Programmer's Guide 1297
:WGEN<w>:MODulation:NOISe
(see page 1428)
Command Syntax
:WGEN<w>:MODulation:NOISe
<percent>
<w> ::= 1 or 2 in NR1 format
<percent> ::= 0 to 100
The :WGEN<w>: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<w>:MODulation:NOISe?
The :WGEN<w>:MODulation:NOISe query returns the percent of added noise.
Return Format
<percent><NL>
<percent> ::= 0 to 100
