Transmit & Receive Antenna VSWR

1X SC 4812T BTS Optimization/ATP Software Release 2.16.1.x
FIELD TRIAL
G-2
Transmit & Receive Antenna VSWR
Purpose
The following procedures will verify that the Voltage Standing Wave
Ratio (VSWR) of all antennas and associated feed lines fall within
acceptable limits. The tests will be performed on all antennas in a
sequential manner (i.e., ANT 1, then ANT 2) until all antennas/feedlines
have been verified.
These procedures should be performed periodically by measuring each
respective antenna’s VSWR (reflected power) to verify that the antenna
system is within acceptable limits. This will ensure continued peak
system performance.
The antenna VSWR will be calculated at the CDMA carrier frequency
assigned to each antenna. Record and verify that they meet the test
specification of less than or equal to 1.5:1.
NOTE
Motorola recommends that the installer be familiar with the
following procedure in its entirety before beginning the actual
procedure. Ensure that the entire site is currently not in service.
This test is used to test RX antennas by substituting RX
frequencies for TX frequencies.
Study the site engineering documents and perform the following tests
only after first verifying that the RF cabling configuration required to
interconnect the BTS frames and antennas meet requirements called out
in the BTS Installation Manual.
Test equipment
The following pieces of test equipment will be required to perform this
test:
LMF
Directional coupler
Communications test set
WARNING
Prior to performing antenna tests, insure that no CDMA BBX
channels are keyed. Failure to do so could result in personal
injury or serious equipment damage.
