[:SOURce<hw>]:IQ:OUTPut[:ANALog]:OFFSet:I
<I>
[:SOURce<hw>]:IQ:OUTPut[:ANALog]:OFFSet:Q
<Q>
Sets an offset V
offset
between the inverting and non-inverting input of the differential
analog I/Q output signal.
The value range is adjusted so that the maximum overall output voltage does not
exceed 4V, see
"Maximum overall output voltage"
Parameters:
<Q>
float
Range:
-2V to 2V
Increment: 1E-4
*RST:
0
Default unit: V

SOURce:LFOutput subsystem
The
SOURce:LFOutput
subsystem contains the commands for setting the LF signal
source in CW and Sweep mode and for analog modulation.
Example: Setup an LF sweep
The following example shows a command sequence to set up an LF sweep.
// Reset the instrument to start from an initial state
*RST; *CLS
// Set the trigger mode, the sweep mode and the sweep range
TRIGger1:LFFSweep:SOURce SINGle
SOURce1:LFOutput1:SWEep:FREQuency:MODE AUTO
SOURce1:LFOutput1:FREQuency:STARt 1 kHz
SOURce1:LFOutput1:FREQuency:STOP 7 kHz
// Select linear spacing
// Select the waveform shape for the frequency sweep cycle
// Set the step width and the dwell time.
SOURce1:LFOutput1:SWEep:FREQuency:SPACing LINear
SOURce1:LFOutput1:SWEep:FREQuency:SHAPe SAWtooth
SOURce1:LFOutput1:SWEep:FREQuency:STEP:LINear 100 Hz
SOURce1:LFOutput1:SWEep:FREQuency:DWELl 150 ms
// Alternatively to the step width set the number of steps
SOURce1:LFOutput1:SWEep:FREQuency:POINts 61
// Activate change to start frequency while waiting for next trigger
// Prerequisites: sweep mode single and sweep waveform sawtooth
