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

Parameter 18, RX Usable Sens Set and Measure

This test parameter allows you to choose how the test for usable sensitivity will be

performed.

For Example:

Setting this test parameter to “

1” causes the software to perform a pass/fail

measurement of the receiver’s usable sensitivity. In this case, the test set RF

generator’s output level is set to the upper limit of

Pass/Fail Limit 13, RX Squelch

Blocking

for “RX usable sensitivity” and the measured SINAD level at the radio’s

output is checked against test

Parameter 18, RX Usable Sens Set and Measure for

“RX usable sensitivity SINAD level”. If the SINAD level is within the specified

limits the test passes and the specified usable sensitivity from

Pass/Fail Limit 13,

RX Squelch Blocking

is displayed in the “Measured value” column.

Setting this test parameter to “

0” causes the software to perform a faster, iterative

measurement of usable sensitivity. In this case, the test set’s RF generator’s output

level is set to the “RX Standard RF Input Level” (determined by the value in test

Parameter 15, RX Squelch Preset Only

). The RF generator’s output level is varied

until the SINAD level measured at the radio’s output. The SINAD level measured

is displayed in the “

Measured value” column as the usable sensitivity SINAD

level.

It’s Used in the Following Tests:

TEST_14. RX Usable Sensitivity

TEST_20. RX Quick Test
