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

Pass/Fail Limit 22, TX Audio Frequency Response Roll >2.3 kHz for 896-940M

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

roll off for measurements greater than 2.3 kHz but less than 2.7 kHz for radio’s in

the frequency range of 896-940 MHz.

Pass/Fail limits are determined from an application 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 roll off for frequencies greater

than 2.3 kHz but less than 2.7 kHz to be a maximum of 6 dB/octave and you want

to test the radio’s upper limits, enter

0 in the lower-limit column and 6 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
