Parameters:
<Source> SOFTware | MARKer
SOFTware
Recording of signals is started automatically in specified inter-
vals. This asynchronous method is appropriate when a repre-
sentative display of the complete signal is desired, as recording
starts in a random time reference to the signal.
MARKer
The starting point for recording signals is determined by "Marker
1" in the menu of the active standard.
This synchronous method is appropriate when specific signal
segments are to be shown in greater detail. With periodic sig-
nals, a static image is obtained by selecting a period length of
"Marker 1" that is equal to the signal period.
The displayed signal segment can be shifted as needed by
entering a "Marker Delay" in the "Trigger/Marker" menu of the
active standard.

7.16.3.5 SOURce:BB:IMPairment Subsystem
This subsystem contains the commands for the digital I/Q impairments.
Included in this section is also the description of command
SOURce:BB:IQOutput:SOURce
that determined the source for the I/Q output con-
nectors.

[:SOURce<hw>]:BB:IMPairment:IQRatio[:MAGNitude] <IqRatio>
This command sets the ratio of I modulation to Q modulation (amplification “imbal-
ance”). The input may be either in dB or %. The resolution is 0.001 dB, an input in per-
cent is rounded to the closest valid value in dB. A query returns the value in dB.
Parameters:
<IqRatio> float
Range:
-1 to 1
Increment: 1E-4
