Digital Modulation Subsystem—N5172B/82B ([:SOURce])
:DM:EXTernal:INPut:ATTen:MODE
Supported N5172B/82B
[:SOURce]:DM:EXTernal:INPut:ATTen:MODE DEFault|MANual|MEASure
[:SOURce]:DM:EXTernal:INPut:ATTen:MODE?
This command selects the external measurement used to set the attenuator level. The modulation
attenuation must be in Auto mode and is enabled by the :DM:EXTernal:INPut:ATTen:AUTO command.
DEFault Use this choice to set the external I/Q input level to the default value of 500.0 mV.
MANual Use this choice to manually set the external input level. The input level is set by
using the :DM:EXTernal:INPut:ATTen:LEVel command.
MEASurement This choice uses a real–time measurement of the external input level to set the
attenuator level. The measurement will be used to set the attenuator level setting
and is performed by using the :DM:EXTernal:INPut:ATTen:LEVel:MEASurement
command.
Example
:DM:EXT:INP:ATT:MODE MAN
The preceding example sets manual as the method for setting the external I/Q input level.

:DM:EXTernal:POLarity
Supported N5172B/82B
[:SOURce]:DM:EXTernal:POLarity NORMal|INVert|INVerted
[:SOURce]:DM:EXTernal:POLarity?
This command, for backward compatibility with older signal generator models, selects normal or
inverted I/Q routing of signals going out of the rear- panel I and Q output connectors. In the inverted
mode, the Q input is routed to the I modulator and the I input is routed to the Q modulator.
Example
:DM:EXT:POL INV
The preceding example inverts I and Q signal routing.
*RST NORM
Key Entry Int Phase Polarity Normal Invert
:DM:INTernal:CHANnel:CORRection[:STATe]
Supported N5172B/82B
[:SOURce]:DM:INTernal:CHANnel:CORRection[:STATe] ON|OFF|1|0
[:SOURce]:DM:INTernal:CHANnel:CORRection[:STATe]?
This command enables and disables the RF and baseband magnitude and phase corrections across
