Compensating for the Loss of an External Cable and Attenuator
The insertion loss of the test cable and high power attenuator must be compensated
for to obtain accurate GSM power measurements. This process is called
“normalization” and is described in “Measuring Two Port Insertion Loss” on
page 124.
The insertion loss of the combination of test cable and attenuator is accounted for as
the RF In Loss, which is an offset applied to the power measurements by the test set.
6 In PvT view, select [RF Envelope], [Upper
Mask], or [Lower Mask].
In Spectrum view, select [Normal] or
[Averaged].
The Trace options you see
depend on which view (PvT or
Spectrum) you are using.
7 Locate the marker relative to the trace:
[Marker to Peak] or [Marker to Next Peak]

3 Enter the RF In loss using the
numeric keypad.
If you are using a cable and additional
devices connected to the antenna, enter the
combined cable and device RF In loss here.
The RF In loss can be obtained by
measuring the Insertion loss. See “Two Port
Insertion Loss” on page 123.
Note: If data had been previously entered in
[RF In Loss], that data will be lost and
replaced by the value you enter here.
