409 User Manual 1176.8674.02 ─ 07
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" on page 140
[:SOURce<hw>]:BB:IMPairment:LEAKage:Q <Q>
This command sets the carrier leakage amplitude for the Q-signal component.
Parameters:
<Q> float
Range:
-10 to 10
Increment: 0.01
*RST:
0
Default unit: PCT
Example: BB:IMP:LEAK:Q 3 PCT
sets the leakage for the Q-component to 3 percent.
Manual operation: See "I/Q Offset" on page 140
[:SOURce<hw>]:BB:IMPairment:QUADrature[:ANGLe] <Angle>
This command sets the quadrature offset for the digital I/Q signal.
Parameters:
<Angle> float
Range:
-10 to 10
Increment: 0.01
*RST:
0
Default unit: DEG
Example: BB:IMP:QUAD:ANGL -5DEG
sets the quadrature offset to -5 degrees.
Manual operation: See "Quadrature Offset" on page 141
[:SOURce<hw>]:BB:IMPairment:SKEW <Skew>
Sets the time offset between the I and Q vectors.
In an I/Q modulator without I/Q skew, the I and Q vectors are aligned to the marker.
With an I/Q skew, both vectors are shifted relative to the marker so that the offset of
each of the vectors to the marker will be the half of the I/Q skew value.
