6.12 Measured offsets
6.12.1 IOffsetH
Inphase noise sampling average on horizontal channel. The value is subtracted from the 'I' data of the
input time samples. It is calculated by noise sample procedure, stored in Frog-Muran software and set by
it.
Type: float
Default: 0.0
Remark: The offsets are only used for lowpass receivers (video processing) as the A/D converter offset is
effectively canceled by the matched bandpass filter.
6.12.2 QOffsetH
Quadrature noise sampling average on horizontal channel. The value is subtracted from the 'Q' data of the
input time samples. It is calculated by noise sample procedure, stored in Frog-Muran software and set by
it.
Type: float
Default: 0.0
Remark: The offsets are only used for lowpass receivers (video processing) as the A/D converter offset is
effectively canceled by the matched bandpass filter.
6.12.3 IOffsetV
Inphase noise sampling average on vertical channel. The value is subtracted from the 'I' data of the input
time samples. It is calculated by noise sample procedure, stored in Frog-Muran software and set by it.
Type: float
Default: 0.0
Remark: The offsets are only used for lowpass receivers (video processing) as the A/D converter offset is
effectively canceled by the matched bandpass filter.
6.12.4 QOffsetV
Quadrature noise sampling average on vertical channel. The value is subtracted from the 'Q' data of the
input time samples. It is calculated by noise sample procedure, stored in Frog-Muran software and set by
it.
