To prevent the operator from changing the setup

Once the setups for each measurement step are properly set up, you may not

want the operator to change anything in the setup, especially when the mask

is related to a particular sensitivity and position setting. However, in some

other situations, you may want the operator to make fine adjustments to fit

the signal inside the testing mask. This is especially true with a mask that

tests the shape of the signal but not the absolute amplitude. The Test

Automation Module allows you to choose three different levels of operator

permission.

•

All Allows the operator to change all of the setups in this step. All the

knobs and keys can be operated by the operator.

•

Adjust Allows the operator to operate the following knobs: Delay,

Time/Div, Volts/div, Position, and the softkeys. All of the other menu keys

are disabled. This allows the operator to fine adjust the fit of the signal

inside the mask. The Volt/Div and Time/Div verniers can be turned on in

the setup for fine adjustments.

•

None The operator is not allowed to change the setup. All of the knobs

and keys except the softkeys and the knob closest to the Cursors key are

disabled.

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 that you want to modify.

5 Press the Define Step softkey.

6 Press the Test Modes softkey.

7 Press the Permit softkey until the desired access ability is shown.
