The System Menu

The @ZGT] key provides access to the system menu. This menu leads to additional menus which control various aspects of the analyzer system. The following softkeys are located within the system menu:

w i&&;&&a allows you to produce me stamps on plots and printouts.

The Limits Menu

This menu can be accessed by pressing ~~~~~~~~~ softkey within the system menu.

..:.. i.~...,...=........;..... .......A.:::::.: ;;;....:...::.,..

You can have limit lines drawn on the display to represent upper and lower limits or device specillcations with which to compare the test device. Limits are defined in segments, where each segment is a portion of the stimulus span. Each limit segment has an upper and a lower starting limit value. Three types of segments are available: flat line, sloping line, and single point.

Limits can be defined independently for the two channels, up to 22 segments for each channel. These can be in any combination of the three limit types.

Limit testing compares the measured data with the defined limits, and provides pass or fail information for each measured data point. An out-of-limit test condition is indicated in five ways: with a FAIL message on the screen, with a beep, by changing the color of the falling portions of a trace, with an asterisk in tabular listings of data, and with a bit in the HP-IB event status register B. (The analyzer also has a BNC rear panel output that includes this status, but is only valid for a single channel measurement.)

Note The limit test output has three selectable modes. For more information, refer to Chapter 2, “Making Measurements. n

Limit lines and limit testing can be used simultaneously or independently. If limit lines are on and limit testing is off, the limit lines are shown on the display for visual comparison and adjustment of the measurement trace. However, no pass/fail information is provided. If limit testing is on and limit lines are off, the specified limits are still valid and the pass/fail status is indicated even though the limit lines are not shown on the display.

Limits are entered in tabular form. Limit lines and limit testing can be either on or off while limits are defined. As new limits are entered, the tabular columns on the display are updated, and the limit lines (if on) are modified to the new definitions. The complete limit set can be offset in either stimulus or amplitude value.
