Pass/fail is carried out by the following steps:
1) Press [UTILITY] to skip to the “UTILITY” menu.
2) Continuously press “Next” to skip to page 3 of the auxiliary menu.
3) Press “Pass/fail” to skip to the “PASS/FAIL” menu.
4) Press “Test allowed” to select “Run”.
5) Press “Signal source selection” to select the signal input channel. In figure 2-73
CH2 is selected.
6) Press “Next Page1/2” to skip to page 2 of the pass/fail menu.
7) Press “Rule setup” to skip to page 2 of the rule setup menu, as shown in figure 2-75.
8) Press “Horizontal regulation” and “Vertical regulation”, and use the [UNIVERSAL]
knob to regulate the horizontal tolerance range and the vertical tolerance range.
9) Press “Build rule” to build a rule template, or press the “Recall” key in the next page
of the menu to recall the saved rules.
10) Get back to skip to page 2 of the pass/fail menu, and set the “Output” option as
pass.
11) Get back to page 1 of the pass/fail menu, and press “Operation” to start.
As shown in figure 2-77, after the rules are built completely, PASS starts counting if
the signal of CH2 satisfies the rules during start, and Pass would stop counting
while Fail would start counting when the signal surpasses the set template (the
amplitude of the signal in the figure is smaller).
Pass/Fail output
The pass/fail function can be used for outputting a negative pulse train through a
Pass/Fail BNC interface on a rear panel of the oscilloscope.
