Pass/Fail Limit (Specification) Descriptions

3. RXA Audio Response Dev from

−

6 dB/oct R2 (dB)

3. RXA Audio Response Dev from −6 dB/oct R2

(dB)

This sets the pass/fail limits used in TEST_06 - TXA Audio Frequency

Response for the receiver’s audio output circuitry, when its audio

response is tested against the standard 6 dB/octave de-emphasis curve.

The audio response should not deviate beyond the pass/fail limits in the

regions of 300 to 400 Hz and 2400 to 3000 Hz. Upper and lower limits

must be entered in dB.

Pass/fail limits are determined by using any applicable standard, such

as:

• EIA/TIA Standard: Voice Audio Frequency Response

Example

If your receivers are normally used with a handset or a line, and the

audio response should not deviate more than +1 to

−6 dB over the

frequency range of 300 to 400 Hz and 2400 to 3000 Hz, enter

−6 as the

Lower Limit and 1 as the Upper Limit.
