Digital Modulation Commands 10
Agilent N8211A/N8212A Performance Upconverter Synthetic Instrument Module, 250 kHz to 20 / 40 GHz 325
:MODulation:ATTen:AUTO
Supported N8212A
[:SOURce]:DM:MODulation:ATTen:AUTO ON|OFF|1|0
[:SOURce]:DM:MODulation:ATTen:AUTO?
Enables or disables the modulator attenuator auto mode. The auto mode will be switched to
manual if the N8211A/N8212A receives a AUTO OFF or AUTO 0 command.
ON (1) Sets the modulator attenuator to auto mode which optimizes the attenuation
setting for the current N8211A/N8212A settings.
OFF (0) Sets the attenuator to manual mode and holds the attenuator at its current
setting. Refer to “:MODulation:ATTen" on page 324 for setting the attenuation value.
Example
:DM:MOD:ATT:AUTO OFF
The example sets the modulator attenuator to manual mode.

:MODulation:ATTen:EXTernal
Supported N8212A
[:SOURce]:DM:MODulation:ATTen:EXTernal DEFault|MANual|MEASure
[:SOURce]:DM:MODulation:ATTen:EXTernal?
Selects the external measurement used to set the attenuator level. Modulation attenuation
“:MODulation:ATTen" on page 324 must be in auto mode.
DEFault Sets the external I/Q input level to the default value of 500.0 mV.
MANual Sets the external input level. Refer to “:MODulation:ATTenn:EXTernal:LEVel" on
page 326 to set the input level.
MEASurement Sets 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. To
perform this measurement, refer to “:MODulation:ATTenn:EXTernal:LEVel" on page 326.
Example
:DM:MOD:ATT:EXT MAN
The example sets manual as the method for setting the external I/Q input level.
