Pass/Fail Limit (Specification) Descriptions

7. RXA Hum and Noise (dB)

This sets the pass/fail limits used in TEST_17 - RXA Hum and Noise

and TEST_24 - RXA Quick General for the hum and noise level of the

receiver. 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: Hum and Noise

Example

If you desire the hum and noise level of the receiver to be at least 32 dB

below the audio output for a 1 kHz modulated RF carrier at

−50 dBm

having a

±8 kHz peak frequency deviation, enter −32 as the Upper

Limit.
