4 Key Reference
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 amplifier. Now,
replace the thru line with the device under
test, and an accurate measurement of the
gain or loss can be made.

Posn
Offsets the displayed trace without affecting
the instrument gain or attenuation settings.
This allows the displayed trace to be moved
without decreasing measurement accuracy.
The normalized reference position is
indicated with a (>) character on the left
side of the display and a (<) character on
the right side of the display.
