ADJUSTMENTS

A8 ADJUSTMENT (37397A)

6-7A8 ADJUSTMENT

The adjustments are important to the operation of the VNA above 56

(37397A)

GHz. Improperly adjusted A8 Potentiometers may cause lock failures.

 

Perform these adjustments as follows:

 

￿ The A8 PCB is replaced.

 

￿ 44733 Buffer Amp is replaced.

Calibration

Perform the following steps:

Procedure

 

 

 

Equipment Required

 

None

 

 

 

NOTE

 

 

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

 

 

performing calibration, and perform the ALC calibration

 

 

(paragraph 6-3) before doing this calibration.

 

Procedure

 

Step 1.

Connect a V Throughline (3670V50-2 with FF Adapter) be-

 

 

tween Ports 1 and 2.

 

Step 2.

Set the 373XXA to sweep from 50 to 65 GHz.

 

Step 3.

Set RF power to 0 dB (default value).

 

Step 4.

Using Diagnostics menu, view Non-Ratio parameters.

 

Step 5.

View Channel 1 (Ref A) only, and activate Autoscale.

 

Step 6.

Adjust the “RA” potentiometer on top of A8 for the flattest

 

 

trace display. A small discontinuity at 56 GHz is normal.

 

Step 7.

Perform Step 6 for each of the four Non-Ratio channels.

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.
