ITCM 32 1.4.0+
Carrier Null Trace. Displays data as CFT
nulling procedure is performed. This data is
displayed during Auto (w 998 1) or Semiauto
CFT nulling (A 74). CFT nulling involves
finding the point at which the rectified IF
voltage (Rect IF Volt A/D) is at a minimum.
Step : Indicates the current offset (I or Q)
difference between subsequent readings.
Step size becomes smaller as RF-O!
transmitter narrows in on best null point.
IOffset : Current setting of the inphase offset
QOffset: Current setting of the quadrature
offset.
Rect IF Volt A/D : Analog-to-digital reading
of the rectified IF voltage. The lower this
value is, the lower the CFT feedthrough is.
* : Indicates when the reading was made,
this combination of I and Q offsets produced
an IF voltage reading less than or equal to
the current lowest value (possible minimum
point).
