Step 8. The result should be within ±0.5 dB of the calculated value. If the insertion loss results
do not agree with the manufacturer’s data, check the cable connectors for proper
connection to the cable, and check for kinks in the cable. If the Spectrum Analyzer has
a distance to fault (DTF) function, this can be used to help troubleshoot kinks in the
cable.
Step 9. Divide this value in half and assign the result to the calibration cable and to the antenna
cable.
Caution: Cables with results greater than the specified limits (i.e., 2 or 3 dB high) should
not be installed, as a potential hardware fault exists.
Step 10. Record the data in the Cable Loss worksheet.
Step 11. Repeat steps 3 through 10 for antenna cables 2 through 8.
Step 12. When finished, take the average of the eight values obtained for the calibration cable.
Use this value for the insertion loss of the calibration cable.
Step 13. Change the frequency to the next test frequency (refer back to Test Setup). Perform
steps 1 through 12 until all cables have been successfully tested at the frequencies
given in Table K4.
RFS Test Box Setup
Step 1. For RFS only testing, connect the power/data test cable to the data connector on the
RFS and to the RFS Test Box.
- OR -
For RFS and cable testing, connect the installation power/data cable to the data
connector on the RFS and to the RFS Test Box.
Refer to Figure K6.
Step 2. Connect the RFS Test Box power supply to the RFS Test Box.
Step 3. Plug the RFS Test Box power supply into a 110/220 VAC, 60/50 Hz outlet.
