Using the Param Compare conditions, each Pass/Fail input (Qx) can compare
a different parameter measurement to a user-defined limit (or statistical
range) under a different condition.
Comparing a Single Parameter
1.
With the ParamCompare condition selected on a Qx dialog, touch
inside the Compare Values field and select All or Any from the pop-
up menu.
By selecting All, the test are true only if every waveform falls within
the set limit. Selecting Any makes the test true if just one waveform
falls within the limit.
2.
Touch inside the Condition field on the ParamCompare part of the
dialog and select a math operator from the pop-up menu.
3.
Touch inside the Limit field and enter a value using the pop-up
numeric keypad. The value entered acquires the dimensions
corresponding to the parameters being tested. For example, if you
are testing a time parameter, the unit is seconds.
If you choose
Condition menu, you also have the choice of setting the limit by
means of the statistical buttons (relating to standard statistical limits)
at the bottom of the ParamCompare dialog:
Comparing Dual Parameters
In Dual Parameter Compare mode, your oscilloscope can take parameter
results measured on two different waveforms and compare them to each
other. If desired, set your test to be true if Any or All waveforms fit the
criteria set by the comparison condition. Setups are conveniently shown in
the Summary box of the Qx dialog as follows (shown on the Dual Param
Compare right-hand dialog):
