To use a mask template for adjustment

A mask template can be used as the guideline, as well as for verifying an

adjustment on a port on the device under test. For the purpose of

adjustment, a good interactive display is important. This requires the

maximum possible update rate. In the Test Automation Module, there is an

Adjust mode for mask template testing. When the adjust mode is turned on,

the Test Automation Module optimizes for maximum update rate. In order to

achieve the maximum update rate, some of the displayed data may not be

tested. The testing rate is maintained at an acceptable level for the

interactive display of action messages. To turn on the adjust mode:

1 Press Print/Utility twice.

2 Press the Sequence Admin softkey.

3 Press the Define Sequence softkey.

4 Press the Step softkey, or turn the knob closest to the Cursors key,

to select the step number for the testing mask number.

5 Press the Define Step softkey.

6 Press the Test Modes softkey.

7 Toggle the Adjust softkey to turn on the adjust mode.

Adjustment operating hint

The Fail Min and Fail Max message can be used as a pair for prompting the

operator for adjustment. For example, the adjustment of the output voltage

from a power supply. When the signal fails the maximum limit, the operator

needs to adjust the variable resistor in the clockwise direction. When the

signal fails the minimum limit, the operator needs to adjust the variable resistor

in the counter-clockwise direction.
