Agilent N8211A/N8212A Performance Upconverter Synthetic Instrument Module, 250 kHz to 20 / 40 GHz 297
Phase Modulation Subsystem ([:SOURce])
:PM[1]|2
Supported All
[:SOURce]:PM[1]|2
Enables the selection of the ΦM path and associated with all SCPI commands in this
subsystem.
PM1 ΦM Path 1 2 with 1 selected
PM2 ΦM Path 1 2 with 2 selected
When just PM is shown in a command, this means the command applies to path 1 only.
Each path is set up separately. When a SCPI command uses PM1, only path one is affected.
Consequently, when PM2 is selected, only path two is set up. However, the deviation of the
signals for the two paths can be coupled.
Deviation coupling links the deviation value of PM1 to PM2. Changing the deviation value
for one path will change it for the other path. These two paths can be on at the same time
provided the following conditions have been met:
dual–sine or sweep–sine is not the selection for the waveform type
each path uses a different source (Internal 1, Internal 2, Ext1, or Ext2)
PM2 must be set to a deviation less than or equal to PM1
:PM:INTernal:FREQuency:STEP[:INCRement]
Supported Option UNT
[:SOURce]:PM:INTernal:FREQuency:STEP[:INCRement]<num>|MAXimum|MINimum|
DEFault
[:SOURce]:PM:INTernal:FREQuency:STEP[:INCRement]?
Sets the step value of the phase modulation internal frequency.
The step value set by this command is used with the UP and DOWN choices for the
“:PM[1]|2:INTernal[1]:FREQuency" on page 299.
The setting enabled by this command is not affected by a power-on, preset, or *RST
command.
