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

Pass/Fail Limit 2, RX Audio Distortion

This defines pass/fail limit values for testing a receiver’s audio distortion when

the radio’s volume is set to the standard input-signal level.

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

standard, such as:

• Radio specification: Audio Distortion

• Industry standard: EIA/TIA-603, Section 2.1.12, Audio Distortion.

For Example:

If your industry standard defines the maximum harmonic distortion as 10% at the

rated output power and you want to test the radio’s upper limits only, enter

0 in

the lower-limit column and

10 in the upper-limit column. Limits are entered in %.

It’s Used in the Following Tests:

TEST_12. RX Audio Distortion

TEST_20. RX Quick Test
