Checking Burst Pulse and AFC with Setup Mb Command

Test Goal

Verify that the TTY setups for the Burst Pulse and AFC Configuration section are properly configured for the customer application.

Background: Magnetron Systems

For magnetron systems, the phase and frequency of the burst pulse from the transmitter is measured at IF.

The phase measurement is used for digital phase locking and second trip echo filtering and recovery.

The frequency measurement is used to implement an analog (±10V) AFC output to control the STALO frequency.

An external AFC can be used instead of RVP10 AFC, but it is not recommended.

Test Equipment

KVM connected

Test Procedure

1. Enter the TTY setups through dspx.
2. Issue the Mb command, once for each pulse width.
3. Set all the values as required.
