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 an in-line wattmeter with appropriate frequency
range and power levels, and low loss cable and connectors. The LMR output is
expected to be in the range of 3 to 5 watts. Record results in Table 9.
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 LMR VSWR procedure. Record result. < 2:1 VSWR (10%)
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).
3. Obtain required signatures and send to BAE Systems, retain file copy.
Table 10. System Functional Test Results
Required Material:
a. VCA100 under test installed in vehicle and configured with user parameters.
b. Known good user mobile or portable radio with the same Frequency and PL Code as the
VCA100 under test.
c. Known good second VCA100 and mobile or portable radio set to a different frequency than the
VCA100 under test with a line-of-sight path more than 100 feet but less than 300 feet
separation between the VCAs.
