Amptd Offset
offsets the displayed power of the tracking generator. Using
the amplitude offset capability of the tracking generator
allows you to take system losses or gains into account,
thereby displaying the actual power delivered to the device
under test.

Copies trace 1 into trace 3. Softkey menu Store
Ref (1->3) must be pressed before pressing
Normalize (On).
Activates the normalize function. On each
sweep, the normalized trace (Trace 3) is
subtracted from Trace 1 and the result is added
to the normalized reference level.
The trace data is normalized with respect to the
normalized reference level, even if the value of
the normalized reference level is changed. This
function remains in effect on all subsequent
sweeps until it is turned off.
The normalize function is most useful for
applying correction data to a trace while
making a stimulus response measurement with
a tracking generator. For example, connect the
cables and a thru line, in place of the device to
be measured, between the tracking generator
and the analyzer input. Notice that the
frequency response is not perfectly flat, showing
the response of the cables, as well as the
flatness of both the tracking generator and the
analyzer. Now press Store Ref (1->3), Normalize
(On). Notice that the displayed trace is now flat,
or normalized. The position of the normalized
trace can now be moved to a different position
on the display by changing the normalized
reference position. This may be useful if the
device to be tested has positive gain, such as an
