Operating Manual 1407.6062.32 ─ 08
Example:
BB:IMP:QUAD:ANGL -5DEG
sets the quadrature offset to -5 degrees.
[: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.
A positive I/Q skew means that the Q vector delays relative to the I vector and vice versa.
Parameters:
<Skew>
float
Range:
-500E-9 to 500E-9
Increment: 1E-12
*RST:
0
Example:
BB:IMP:SKEW 410.0E-9
sets the I/Q skew.
[:SOURce<hw>]:BB:IMPairment:STATe
<State>
The command activates (ON) and deactivates (OFF) the three impairment or correction
values LEAKage, QUADrature and IQRatio for the digital baseband signal prior to input
into the I/Q modulator.
Parameters:
<State>
0 | 1 | OFF | ON
*RST:
0
Example:
BB:IMP:STAT OFF
deactivates digital impairment.

SOURce:BB:MCCW Subsystem
This subsystem contains the commands for setting the Multi Carrier CW signals.
Suffixes
SOURce<hw>
For one-path instruments, the keyword SOURce is optional and can be omitted.
The numeric suffix to
SOURce
distinguishes between signal generation for path A and
path B in the case of two-path instruments:
●
SOURce[1]
= path A
The keyword
SOURce
is optional and can be omitted
●
SOURce2
= path B
The keyword
SOURce
is mandatory, i.e. the command must contain the keyword with
suffix 2.
