6.16. P25 Phase II Modulation Fidelity
NOTE: This test requires an analyzer with P25 Phase 2 Test Mode (R8-P25_II
option) capability.
The purpose of this procedure is to measure the radio transmitter’s P25 Phase 2
Modulation Fidelity at a given frequency. Modulation Fidelity represents how accurately
a P25 Phase 2 transmitter reproduces an ideal theoretical modulation waveform. The
TIA/EIA-102.CCAB measurement standard max limit is 5%. This is a test only; there is
no alignment.

Table 6-30. Analyzer Configuration for P25 Phase 2 Modulation Fidelity test
6.16.1. Test
The analyzer is setup as specified in this section’s Analyzer Configuration table. The
radio is placed into Test Mode at the lowest Tx Test Frequency and configured to
generate the indicated P25 Phase 2 waveform signal. The analyzer measures the
Modulation Fidelity response which is compared against test limits and the final results
are written to the log file.
