326 Agilent N8211A/N8212A Performance Upconverter Synthetic Instrument Module, 250 kHz to 20 / 40 GHz
10 Digital Modulation Commands
*RST DEFault
:MODulation:ATTenn:EXTernal:LEVel
Supported N8212A
[:SOURce]:DM:MODulation:ATTen:EXTernal:LEVel <val><volt_units>
[:SOURce]:DM:MODulation:ATTen:EXTernal:LEVel?
Sets the I/Q signal voltage level at the external I/Q inputs. The voltage level set with this
command is used as the input level setting for automatic attenuation.
Example
:DM:MOD:ATT:EXT:LEV 100MV
The example sets the voltage level for the I and Q inputs to 100 mV.
*RST +4.00000000E−001
Range .05–1 Volt
:MODulation:ATTenn:EXTernal:LEVel:MEASurement
Supported N8212A
[:SOURce]:DM:MODulation:ATTen:EXTernal:LEVel:MEASurement
Measures the RMS value of the external I/Q signal. The external input level must be set to
Meas.
:MODulation:ATTen:OPTimize:BANDwidth
Supported N8212A
[:SOURce]:DM:MODulation:ATTen:OPTimize:BANDwidth <val><rate>
[:SOURce]:DM:MODulation:ATTen:OPTimize:BANDwidth?
Sets the expected bandwidth of the external I/Q signal. The bandwidth set with this
command be used by the modulator attenuator for level setting.
The variable <val> is a number within the range limits and the variable <rate> is expressed
as samples per second (sps, ksps, or msps).
Example
:DM:MOD:ATT:OPT:BAND .250MSPS
The example measures the voltage level at the external I/Q inputs.
