4. If any of the waveform generators are multichannel (33522A), you
should phase sync the two channels to each other. This operation will
also synchronize each channel’s modulating waveforms to the carrier.
Front panel operation: Press
or or . Then press
,
Phase
, and
Sync Internal
.
Remote Interface Operation:
[SOURce[1|2]:]PHASe:SYNChronize
5. Leaving the phase setting at its default (zero) on the first waveform
generator, use the Adjust Phase feature to adjust the phase of the
second waveform generator to align the output signals:
You can use the Set 0 Phase feature to set a new zero-phase reference
point with the two waveform generators now aligned.
• Front-Panel Operation: Press
or or . Then press
,
Phase
, and set the phase angle using the numeric keypad or
knob. Once aligned, set the 0 phase.
• Remote Interface Operation: Use the following command to set the
phase offset (the query returns the currently set offset):
[SOURce[1|2]:]PHASe {<angle>|MINimum|MAXimum}
[SOURce[1|2]:]PHASe? [MINimum|MAXimum]
• The following command sets a new zero-phase reference point:
[SOURce[1|2]:]PHASe:REFerence
