ADJUSTMENTS

A21A2 ADJUSTMENT (37397A)

Procedure

Step 1. With power off and the new part installed, disconnect the

RF cable from J4 of the Switched Filter.

Step 2. Install Power Sensor (use a 6 or 10 dB pad for protection) to Switched Filter J4.

Step 3. Turn on the 373XXA and set it to 38 GHz, CW.

Step 4. Adjust A21A2R238 for maximum power, but not over +26 dBm.

Step 5. Remove the pad and sensor and reconnect the RF cable to

J4.

Step 6. Perform the procedures in paragraph 6-4 and 6-5 (fre- quency and ALC calibrations).

Post Calibration After the calibration process is completed, perform the following ac- Actions tions, as appropriate:

If calibration passes:

Save the calibration data to (hard) disk, as follows:

Step 1. Press the Option Menu key (Enhancement key group) to dis- play the OPTIONS menu.

Step 2. Select DIAGNOSTICS from menu.Then select in se- quence: H/W CALIBRATIONS DISK OPERATIONS SAVE TO HARD DISKHW_CAL.SLT.

NOTE

Also save the calibration data to floppy disk for archival purposes as a backup in case of a hard disk failure. Label the disk with cali- bration type, date, and system model and se- rial numbers. Set the copy protect tab on the disk. Properly safeguard the disk so that it will be available for later use, as needed.

If calibration fails:

Repeat the calibration. If it still fails, then proceed to Chapter 5, Trou- bleshooting.
