    Operation 3 Operation This Section describes the verification of the operation and control of the transmitter module. It shall be performed by authorized personnel prior to maintenance and/or repair. Procedure Verify that the installation procedure described in Section 2 was completed. A complete physical check of the customer’s system is suggested.
  • Page 22 Operation CAUTION! It is strongly recommended not to exceed -5 dBm maximum IF Input level. The transmitter module will be in deep saturation if overdriven. RF performance will degrade significantly, and proper operation will not be possible. This operational condition is the survival mode for the transmitter module.

  • Page 23: Maintenance

    Maintenance 4 Maintenance This Section contains information on how to maintain and troubleshoot the transmitter module. The transmitter module is extremely reliable, requiring very little preventive maintenance or repair. Should there be a malfunction, this Section also contains technical information to help diagnose basic failures.

  • Page 24: Transmitter Module Cooling System Preventive Maintenance

    Maintenance With an IF Input signal level within the small signal region of the transmitter module, measure the VSWR (Return Loss) at the RF input and RF output. Refer to the outline drawing in Appendix A. Plot the swept return loss for both the IF Input and RF Output signals on a test data sheet.
