3.5.3 Limit Test
The limit test function is used to compare the measured data and defined constraints (limits). The limits defined by
the user are intuitively displayed on the screen in the limit line form. The limit lines have the following advantages:
➢
Provide intuitive indicators for the device commissioning personnel.
➢
Provide the standards of characteristic indicators of the device.
➢
Provide the intuitive comparison between the measured data and indicators of the device.
The limit test function is used to compare the measured data and defined limits, and provide PASS and FAIL
information. Each trace supports up to 100 separate limit segments for accurate definition.
3.5.3.1 Creating and Editing of Limit Line
The analyzer supports creating of limit lines for all measured traces. The limit line is composed of several separate
segments which are respectively determined by four coordinate values: X-axis start and stop stimulus value and Y-
axis start and stop response value. It is created and edited according to the limit table.
1) Menu path: [Analysis] > [Test] > [Limit Test] . The test dialog box will appear.
2) Click [Show Table] in the dialog box to display the limit table.
3) Click [OK] to close the dialog box.
4) Click [Limit Type] in the limit test dialog box and select the limit test type in the drop-down box.
