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.

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.
