320 Agilent N8211A/N8212A Performance Upconverter Synthetic Instrument Module, 250 kHz to 20 / 40 GHz
10 Digital Modulation Commands
*RST +6.00000000E+000
Range 0–40
:IQADjustment:EXTernal:QOFFset
Supported N8212A
[:SOURce]:DM:IQADjustment:EXTernal:QOFFset <val><units>
[:SOURce]:DM:IQADjustment:EXTernal:QOFFset?
Sets the offset voltage for a signal applied to the 600 ohm Q input connector. The variable
<val> is a numeric expression. The <units> variable is expressed in volts (mV–V).
This command is effective only if the state of the I/Q adjustment function is set to ON.
Refer to “:IQADjustment[:STATe]" on page 332.
Example
:DM:IQAD:EXT:QOFF 200MV
The example sets a 200 mV offset for the signal applied to the Q 600 ohm input connector.
*RST +0.00000000E+000
Range −5 to 5
:IQADjustment:GAIN
Supported N8212A
[:SOURce]:DM:IQADjustment:GAIN[1|2] <val>
[:SOURce]:DM:IQADjustment:GAIN?
Sets the gain for the I signal (GAIN 1) relative to the Q signal, (GAIN 2). The gain ratio is
expressed in decibels (dB).
This command is effective only if the state of the I/Q adjustment function is set to ON.
Refer to “:IQADjustment[:STATe]" on page 332.
Example
:DM:IQAD:GAIN2 -3
The example sets a gain of –3 dB for the Q signal relative to the I signal.
*RST +0.00000000E+000
Range −4 to 4 dB
