7.0 Unit Test Plan
Follow the test procedures described in Paragraphs 7.1 and 7.2. Correct any problems
found, retest, and record final results on the INSTALLATION SIGN OFF SHEET (Appendix E).
7.1 LMR Antenna VSWR Test
Perform an antenna VSWR test using the antenna manufacture’s procedure or a
standard industry accepted procedure. Record results in Table 9.
Note
THIS TEST IS NOT REQUIRED IF THE ANTENNA WAS TERMINATED BY THE OEM AND
HAS NOT BEEN MODIFIED.
Table 9. LMR Antenna VSWR Test Results
Required Material:
a. VCA100 installed in vehicle with LMR Antenna and cable under test
b. Antenna OEM’s VSWR procedure (or standard industry accepted VSWR procedure)
c. Watt meter
Step Procedure Requirement Result
1 Perform selected VSWR procedure. Record result. < 2:1 VSWR
7.2 System Functional Test
1. Follow the test steps in Table 10 to verify the VCA100’s key functions and its ability
to operate in a network.
2. Correct any problems found, retest, and record final results on the INSTALLATION SIGN
OFF SHEET (Appendix E).
Table 10. System Functional Test Results
Required Material:
a. VCA100 under test installed in vehicle and configured with user parameters
b. Known good user LMR with the same Frequency and PL Code as the VCA100 under test
c. Known good second VCA100 and LMR set to a different frequency than the VCA100 under
test
Step Procedure Expected Result Verified
1
Turn on VCA100 under test. Wait one minute for boot
up to complete.
Boot up complete
2
Turn on LMR associated with the VCA100 under test.
Verify the proper channel is selected.
Proper channel selected
3
Turn on known good second VCA100. Wait one minute
for boot up to complete.
Boot up complete
4
Turn on LMR associated with known good VCA100.
Verify proper channel is selected.
Proper channel selected
5
Verify 2-way communication through both units occurs
without distortion, breakup, or dropouts. Record final
result on Installation Sign Off Sheet.
Communication is good
