*RST +0.00000000E+000
:IQADjustment:EXTernal:COFFset
Supported N8212A
[:SOURce]:DM:IQADjustment:EXTernal:COFFset <units>
[:SOURce]:DM:IQADjustment:EXTernal:COFFset?
Sets the common mode offset voltage for both the in-phase (I) and quadrature-phase (Q)
signals going to the rear-panel I and Q output connectors.
The <units> variable is expressed in volts (mV–V). his 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:COFF -.1
The preceding example sets a negative .1 V common mode offset voltage for the I and Q
signals.
*RST +0.00000000E+000
Range −3 to 3
:IQADjustment:EXTernal:DIOFfset
Supported N8212A
[:SOURce]:DM:IQADjustment:EXTernal:DIOFfset <val><units>
[:SOURce]:DM:IQADjustment:EXTernal:DIOFfset?
Sets the differential offset voltage for an in-phase (I) signal routed to the I 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:DIOF 1
The example sets a 1 V differential offset voltage for the I signal at the I output connector.
