Using the RF Tools Program
3. Position the cursor at DUPLEX OUT Level in dBm and enter the
power level at which the test should be conducted.
4. Press
k1
(Begin Tst) to begin the test.

5. A screen appears with a setup diagram. (Figure 4-9) This test
requires two 6-dB pads. The pads are put on the ANT IN and
DUPLEX OUT ports on the Test Set to reduce impedance mismatch
error at these ports. A reference level is obtained by connecting a
short calibration cable between the pads on the DUPLEX OUT and
ANT IN ports. Press
k1
(Proceed).
6. After the Test Set has finished calibrating, a second diagram
appears on the screen. Connect the test cable or device to be tested
between the calibration cable and one of the pads. Press
k1
(Proceed).
7. The discrete frequency insertion loss results screen appears with the
results of the test. The loss is expressed as a negative number in this
particular test.
NOTE
The insertion loss at the specified frequency is displayed twice. The
second display is enlarged for easier reading.
8. Press
k1
(Proceed) when you are finished with this screen. The
Discrete Frequency Insertion Loss Test menu appears. If you would
like to repeat the measurement press
k1
(Begin Tst). The
calibration step will be skipped if none of the parameters were
changed. To exit the test press
k5
(Return).
