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

Parameter 1, RT External Pad and Cable Loss

This test parameter allows you to set the amount of loss for any external cables or

pads (attenuators) that may be connected to the test set.

Besides being used in the tests shown below, pad and cable loss is compensated

for in power measurements and in signal generator level settings by subroutines in

the software whenever:

❒ a reading in Watts is converted to dBm.

❒ finding the radio’s squelch sensitivity.

❒ setting the test set’s RF level to the desired level in dBm.

For Example:

If a 30 dB attenuator is connected in line with the radio’s antenna, enter

30 in the

value column. The value is entered in dB.

It’s Used in the Following Tests:

TEST_14. RX Usable Sensitivity

TEST_15. RX Audio Squelch Sensitivity

TEST_17. RX CTCSS/CDCSS Opening
