Pass/Fail Limit 29, TX FM Hum and Noise
This sets the pass/fail limits for testing a transmitter’s FM hum and noise.
Pass/Fail limits are determined from an applicable radio specification or industry
standard, such as:

• Industry standard: EIA/TIA, Section 2.2.8, FM Hum and Noise Ratio
For Example:
If your radio specification defines the FM noise as
−35 dB and you want to test the
radio’s upper limits, enter
0 in the lower-limit column and −35 in the upper-limit
column. Limits are entered in dB.
