What does the '43 MOD' setting do on VIAVI's IFR6000, IFR6015, and AVX-10K test equipment?
The '43 MOD' setting on VIAVI's test equipment is designed to accommodate aircraft with high-gain antennas. When enabled:
VIAVI Solutions Inc.
The upper power limit of +57 dBm is removed, allowing for accurate testing without false failures due to antenna gain.
The minimum power output requirements remain enforced.
If the output power exceeds the standard limit by no more than 3 dB and all setup parameters are correct, the reading is considered acceptable.
This setting ensures that transponder systems with high-gain antennas can be accurately tested without misinterpretation of the results.
