The Limits Menu
This menu can be accessed by pressing ~~~~~~~~~ softkey within the system menu.
You can have limit lines drawn on the display to represent upper and lower limits or device
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.)
The limit test output has three selectable modes. For more information, refer to
Note
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 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.
