LO 2 CALIBRATION

ADJUSTMENTS

 

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.LO1.

 

 

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:

 

Step 1.

Repeat the calibration. If it still fails, then proceed to

 

 

Chapter 5, Troubleshooting.

6-3LO 2 CALIBRATION

This procedure uses the 373XXA internal diagnostics and calibration

 

menus to adjust the A2 2nd LO PCB assembly. Perform this calibation

 

procedure if:

 

￿ The A2 PCB is replaced.

 

￿ BBRAM chip on A9 Processor PCB is replaced and the LO2 Cali-

 

bration data was not previously saved on disk (that is, data is not

 

available for recall from a floppy disk).

Calibration

Perform the following steps:

Procedure

 

 

Equipment Required

None

NOTE

Allow the 373XXA to warm-up at least 30 minutes prior to performing calibration.

Procedure

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