318 Agilent N8211A/N8212A Performance Upconverter Synthetic Instrument Module, 250 kHz to 20 / 40 GHz
10 Digital Modulation Commands
Range −3 to 3
:IQADjustment:EXTernal:DQOFfset
Supported N8212A
[:SOURce]:DM:IQADjustment:EXTernal:DQOFfset <val><units>
[:SOURce]:DM:IQADjustment:EXTernal:DQOFfset?
Sets the differential offset voltage for a quadrature-phase (Q) signal routed to the Q output
connectors.
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:DQOF 1
The preceding example sets a 1 V differential offset voltage for the Q signal at the Q
connector.
*RST +0.00000000E+000
Range −3 to 3
:IQADjustment:EXTernal:GAIN
Supported N8212A
[:SOURce]:DM:IQADjustment:EXTernal:GAIN[1|2] <val><units>
[:SOURce]:DM:IQADjustment:EXTernal:GAIN?
Sets the I/Q gain ratio (I/Q balance) for signals routed to the rear-panel I and Q output
connectors. The I signal (GAIN 1) is increased for positive values and the Q signal (GAIN 2)
level increases with negative values
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:GAIN1 1
The example sets a Q gain ratio of 1 V.
