19. TXA FM Hum and Noise (dB)
This sets the pass/fail limits for the transmitter’s residual FM hum and
noise. Only the upper limit is used, which must be entered in dB.
Pass/fail limits are determined by using any applicable standard such
as:
EIA/TIA Standard: FM Hum and Noise
Example
If you desire that FM hum and noise should be at least 32 dB below the
level of a 1 kHz tone at
±8 kHz deviation, enter 32as the Upper Limit.
