Chapter 4, Test, Parameter, and Pass/Fail Limit Descriptions
Pass/Fail Limit 5, TX Audio Frequency Response Roll >2.5 kHz
Pass/Fail Limit 5, TX Audio Frequency Response Roll >2.5 kHz
This sets the pass/fail limits for testing a transmitter’s audio-frequency-response
roll off for measurements greater than 2.5 kHz.
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 2.1.10, Audio Frequency Response.
For Example:
If your radio specification defines audio response roll off for frequencies greater
than 2.5 kHz to be a maximum of 12 dB/octave and you want to test the radio’s
upper limits, enter
0 in the lower-limit column and 12 in the upper-limit column.
Limits are entered in dB.
It’s Used in the Following Tests:
TEST_13. RX Audio Frequency Response
TEST_20. RX Quick Test
