Upgrading a 20 GHz Cassini to 40 GHz requires the following steps to be followed:
1. Follow the procedure to Adding SRC3 RI7725 to a Cassini System
2. For the first 40 GHz TIM, insert into T-4 and follow the procedure to Adding Another Test Instrument Module (TIM) into a Cassini System. (Do Not add both at the same time. This allows the tester to assign the instrument names in a specific order.)
Note: Step 5 involves updating the Cal list. This can be done now or after adding Testhead402, but does not have to be repeated.
3. For the second 40 GHz TIM, insert into T-5 and follow the procedure to Adding Another Test Instrument Module (TIM) into a Cassini System. Confirm Testhead40 is in T4 and Testhead402 is in T5 using the Configuration window (System > Tester).
4. After running Diags, perform a complete RF System Calibration, any stand-alone TIM calibrations can be safely skipped. See an updated list list of stand-alone TIMs on the roos.com/maintenance page.
