5.2.19 PHASeSubsystem
The PHASe subsystem allows you to adjust the waveform phase; this is useful in
channel-to-channel and channel-to- ync applications. This subsystem also allows you to use the
10 MHz Out
and
10 MHz In
rear-panel connectors to synchronize multiple instruments.
SOURce<n>:PHASe -
sets phase offset of output waveform (not available for arbitrary waveforms
or noise)
SOURce<n>:PHASe:SYNChronize -
synchronizes phase of both internal channels on a
two-channel instrument.
SOURce<n>:PHASe <phase>|MINimum|MAXimum
SOURce<n>:PHASe? [MINimum|MAXimum]
Sets waveform's phase offset angle.
Parameter
Typical Return
0 to 360degrees, default 0
+9.000000001
Set channel 1 phase offset to 90 degrees: SOURce1:PHASe 90
Use
PHASe:SYNChronize
to synchronize the phases of the two internal channels.
SOURce<n>:PHASe:SYNChronize
Simultaneously resets all phase generators in the instrument to establish a common, internal
phase zero reference point.
Parameter
Typical Return
none
none
Reset all phase generators: PHAS:SYNC
SOURce1 and SOURce2 mean nothing for this command.
The setting is invalid when any channel is in a modulation mode in two channels.
5.2.20 PM Subsystem
The PM subsystem allows you to phase modulate a waveform.
SOURce<n>:MOD:PM:DEViation <deviation>|MINimum|MAXimum
SOURce<n>:MOD:PM:DEViation? [MINimum|MAXimum]
Sets the phase deviation in degrees. This value represents the peak variation in phase of the
modulated waveform from the carrier waveform.
Parameter
Typical Return
0 to 360degrees, default 180degrees
+9.00000000001
Set phase deviation to 90 degrees: SOURce1:MOD:PM:DEViation 90
