Chapter 4, Test, Parameter, and Pass/Fail Limit Descriptions

Pass/Fail Limit 20, TX Audio Response Delta From 6 dB/oct

This sets the pass/fail limits for testing a transmitter’s audio-frequency-response

variation from a true 6 dB/octave pre-emphasis slope.

Pass/Fail limits are determined from an applicable radio specification or industry

standard, such as:

• Radio standard: Audio Response

• Industry standard: EIA/TIA-603, Section 2.2.6, Audio Frequency Response

For Example:

If your radio specification defines audio response to be within +1 and

−3 dB of

6 dB/octave pre-emphasis characteristic and you want to test both limits on the

radio, enter

−3 in the lower-limit column and 1 in the upper-limit column. Limits

are entered in dB.

It’s Used in the Following Tests:

TEST_05. TX Audio Frequency Response

TEST_21. TX Quick Test
