690 Operating Manual 1176.8016.02 ─ 17
Parameters:
<Delay> float
Range:
-500E-9 to 500E-9
Increment: 1E-12
*RST:
0
Example: BB:IMP:DEL 32.0E-9
sets the I/Q delay
Manual operation: See "IQ Delay" on page 307
[: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
*RST:
0
Example: BB:IMP:IQR 3 PCT
sets the imbalance to 3 percent.
BB:IMP:IQR?
queries the imbalance.
Response: 0.259000
the value is returned in dB
Manual operation: See "Gain Imbalance - Digital Impairments" on page 306
[:SOURce<hw>]:BB:IMPairment:LEAKage:I <I>
This command sets the carrier leakage amplitude for the I-signal component.
Parameters:
<I> float
Range:
-10 to 10
Increment: 0.01
*RST:
0
Default unit: PCT
Example: BB:IMP:LEAK:I 3 PCT
sets the leakage for the I-component to 3 percent.
Manual operation: See "I/Q Offset - Digital Impairments" on page 306
[:SOURce<hw>]:BB:IMPairment:LEAKage:Q <Q>
This command sets the carrier leakage amplitude for the Q-signal component.
