R&S®SML / R&S®SMV03 Vector Modulation (R&S SMV03 only)
1090.3123.12 E-6 4.45
I/Q IMPAIRMENT
For simulating an impairment of the vector modulation, a residual carrier (LEAKAGE), imbalanced I and
Q modulation (IMBALANCE) and a quadrature offset can be entered. The input values for LEAKAGE
and IMBALANCE are with reference to the voltage.
.Table 4-1 Parameter setting ranges
Parameter Setting range Resolution
LEAKAGE 0 ... 50 % 0,5 %
IMBALANCE -12 ... +12 % 0,1 %
QUADRATURE OFFSET -10 ... +10° 0,1°
