ADJUSTMENTS

SOURCE LOCK THRESHOLD

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.ALC.

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 (ALC), date, and system model and serial numbers. Set the copy protect tab on the disk. Properly safeguard the disk so that it will be available for later use, as needed.

Perform the RF Power Generation and Control test in Chapter 3, Op- erational Tests. If the test fails, proceed to Chapter 5, Troubleshooting.

 

If calibration fails:

 

￿ Verify the GPIB cable is connected to the Dedicated GPIB (bot-

 

tom) connector on the 373XXA rear panel.

 

￿ Verify that the power meter and sensor are functioning correctly,

 

the cables are in good condition, and all connections are secure.

 

￿ Verify the correct power sensor data exists in the power meter.

 

￿ Note the failed step in the calibration procedure from the screen

 

messages.

 

￿ Repeat calibration. If it still fails then proceed to Chapter 5,
