Equipment Setup - HP Test Set
Follow the procedure in Table G-1 to set up test equipment required to
measure and calculate the VSWR for each antenna.
Table G-1: VSWR Measurement Procedure - HP Test Set
Step Action HP TEST SET
1 If you have not already done so, refer to the procedure in Table 3-2 on page 3-6 to set up test
equipment & interface the LMF computer to the BTS.
2 For manual VSWR testing, using external directional coupler, refer to Figure G-1 (1700/1900 MHz)
or Figure G-2 (800 MHz).
- Connect the communications test set RF OUT ONLY port to the INPUT port of the directional
coupler.
- Connect the RF IN/OUT port of the communication test set to the reverse (RVS) port on the
directional coupler. Terminate the forward port with a 50 ohm load.
- Install the antenna feed line to the output port on the directional coupler.
NOTE
Manual Communications Analyzer test setup (fields not indicated remain at default):
Set screen to RF GEN.
- For 1900 MHz systems, set the RF Gen Freq to center frequency of actual CDMA carrier
between 1930-1990 MHz for TX and 1850-1910 MHz for RX. For 800 MHz systems, set the
RF Gen Freq to center frequency of actual CDMA carrier between 869-894 MHz for TX and
824-849 MHz for RX. For 1700 MHz systems, set the RF Gen Freq to center frequency of
actual CDMA carrier between 1840-1870 MHz for TX and 1750-1780 MHz for RX.
- Set Amplitude to -30 dBm.
- Set Output Port to RF OUT.
- Set AFGen1 & AFGen2 to OFF.
3 Remove the antenna feed line and install an “RF short” onto the directional coupler output port.
NOTE
Set-up communication test set as follows (fields not indicated remain at default):
Set screen to SPEC ANL.
- Under Controls, set input port to ANT.
-
Set Ref Level to -40 dBm.
- Under Controls, select Main, select Auxiliary.
- Under Controls, select AV G. Set Avg = 20.
4 - Record the reference level on the communications analyzer and Note as P
S
for reference.
- Replace the short with the antenna feedline. Record the reference level on the communications
analyzer and Note for as P
A
reference.
- Record the difference of the two readings in dB.
