Chapter 4, Test, Parameter, and Pass/Fail Limit Descriptions
Pass/Fail Limit 39, TX Residual AM Hum and Noise
Pass/Fail Limit 39, TX Residual AM Hum and Noise
This sets the pass/fail limits for testing the transmitter’s residual AM hum and
noise.
Pass/Fail limits are determined from an applicable radio specification or industry
standard, such as:
• Radio specification: Residual AM Hum and Noise
• Industry standard: EIA/TIA-603, Section 2.2.9, AM Hum and Noise Ratio
For Example:
If your radio specification defines residual AM hum and noise as 2% AM and you
want to test the radio’s upper limits, enter
0 in the lower-limit column and 2 in the
upper-limit column. Limits are entered in % AM.
It’s Used in the Following Tests:
TEST_09. TX Residual AM Hum and Noise
TEST_21. TX Quick Test
