The radio then generates a High modulation tone and the RMS-averaged deviation of this tone is measured with the analyzer. The radio softpot is adjusted until the deviation difference between the first and second tones is within test limits. This adjustment is performed for each TX.

The analyzer applies an audio tone to the radio sufficient for the radio s deviation to achieve 60% rated deviation, RMS-averaged. For 25 khz channel spacing, 60% of rated deviation (5 khz) is 3 khz. Once this 60% rated deviation level is achieved, the analyzer adjusts the audio level to 20 db greater than that required to produce 60% rated deviation. The deviation level of this tone is measured with the analyzer. The percent difference is compared against test limits and written to the log file. This test is performed for each remaining TX. 9

Basic Troubleshooting Symptom Possible Cause Possible Solution MOTOTRBO Mobile radio Loose PMKN4016_ Verify cable connection is OK. won t power up cable connection Motorola CPS Ignition Switch setting Use Motorola CPS software to set Radio Wide, Advanced, Ignition Switch setting to Blank. This setting lets radio power up for testing without an ignition signal present. Be sure to return this setting to its original value when Analyzer consistently fails to communicate with MOTOTRBO portable radio Radio consistently fails TX Power Out test and/or alignment Front End Filter test fails one or more points. Cannot adjust measured deviation during Internal Voice Modulation test. Worn programming cable connection MOTOTRBO Family CPS Transmit Power Level settings limiting radio output power. Poor RF cable Table 8-1. AutoTune Troubleshooting Chart General Settings > Mic Selection Rule set to Default. testing completed. Verify programming cable connection to radio is sound. Using same connection, verify radio can be queried using Motorola Tuner software. Using MOTOTRBO Family CPS, adjust Codeplug Configuration Mode>Radio Wide>Transmit Power Level settings to factory defaults. This change lets radio output expected power levels for correct AutoTune TX Power Out testing and alignment. Use a known good quality RF cable when performing the Front End Filter alignment or test. Recommended cable: MegaPhase RF Orange Type N to BNC cable. When Mic Selection Rule is set to Default, the external microphone is effectively always on, preventing the radio s internal microphone from picking up audio. For the Internal Voice Modulation test to work, the radio s internal microphone must be enabled. Change the Mic Selection Rule setting to Mic Follow PTT to allow radio internal microphone to be enabled when the radio PTT is pressed. 40

However, if extenuating circumstances cause a need to modify the limits this is accommodated by AutoTune. Refer to the R8000 Series Communications System Analyzer Owner s Manual (CG-1365) for modification instructions. The following tables list the default test limits for each MOTOTRBO radio model supported by AutoTune. A-1
