Parameter 29, TX Mic Sens Set and Measure
Parameter 29, TX Mic Sens Set and Measure
This test parameter allows you to choose how the test for microphone sensitivity
will be performed.
For Example:
Setting this test parameter to “
0” causes the software to perform a pass/fail
measurement of the microphone’s sensitivity. In this case, the test set’s AF
generator’s output level is set half-way between the lower and upper limits of
Pass/Fail Limit 24, TX Audio Frequency Response Roll >2.7 kHz for 896-940M
for
“TX microphone sensitivity” and the measured deviation is checked against the
half-way limits of
Pass/Fail Limit 21, TX Audio Frequency Response Roll <0.5 kHz
for “TX deviation if set and measure mic sens” to see if the test passes or fails.
The measured microphone sensitivity in mVrms is displayed in the “
Measured
value
” column.
Setting this test parameter to “
1” causes the software to perform a faster, iterative
measurement of microphone sensitivity. In this case, the test set AF generator’s
output level is set to the half-way value of
Pass/Fail Limit 24, TX Audio
Frequency Response Roll >2.7 kHz for 896-940M
“TX microphone sensitivity” and
the deviation measured at the microphone input. The measured results in kHz are
displayed in the “
Measured value” column.
It’s Used in the Following Test:
