Figure 18 Set Up for Cable Loss Measurement
5. Select the Freq softkey and set the frequency start and stop to a
range that is well beyond the normal range of the antenna (refer
to
Setting the Measurement Frequency, page 18).
 Note: For example, for a 450 MHz antenna, set the start
frequency at 400 and the stop frequency at 500 MHz, for an 800
MHz antenna, set the start frequency at 700 and the stop fre-
quency at 1,100 MHz.
6. Connect a phase stable cable to the Site Analyzer antenna test
port and connect a Cal Combo to the other end of the cable.
7. Calibrate the Site Analyzer (See Calibrate the Site Analyzer, page 21).
 Note: After calibration, with the load still connected, the
output must below -25 dB. If it is not, there is a problem.
8. Remove the Cal Combo unit from the cable. Do not disconnect the
phase stable cable from the Site Analyzer.
