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

Parameter 9, RX CT/CDCSS Control

This test parameter allows the receiver’s audio-squelch circuitry for Continuous

Tone-Controlled Squelch System (CTCSS) or Continuous Digital-Controlled

Squelch System (CDCSS) to be controlled by the test operator.

This test parameter affects all receiver tests in that if the radio uses CTCSS or

CDCSS squelch and you indicate that no control is available, then the software

does not prompt the test operator to disable the RX tone squelch during testing but

continues testing by enabling the test set’s tone or code which un-squelches the

receiver.

For Example:

If you want to prompt the test operator to disable the tone squelch during testing,

enter

1 in the value column, otherwise, enter 0 in the value column.

It’s Used in the Following Tests:

All receiver tests when CTCSS or CDCSS is available (as indicated by

TEST_08.
