Automatic Measurement Prerequisites

This section gives you some helpful pointers to help you make
automatic measurements easier.

Measurement Setup Requirements

Measurements typically should be made at the fastest possible sweep speed
in order to obtain the most accurate measurement possible. You can only
make automatic measurements with data that is currently being displayed in
the waveform display area. Keep the following in mind when making
measurements:
•
At least one full cycle of the waveform, with at least two like edges, must
be displayed for Period and Freq measurements.
•
A complete positive pulse must be displayed to make a +Width
measurement.
•
A complete negative pulse must be displayed to make a −Width
measurement.
•
The leading (rising) edge of the waveform must be displayed for Risetime,
and rising edge Preshoot and Overshoot measurements.
•
The trailing (falling) edge of the waveform must be displayed for Falltime,
and falling edge Preshoot and Overshoot measurements.
•
Risetime, Falltime, Preshoot, and Overshoot measurements will be more
accurate if you expand the edge of the waveform by selecting a faster
sweep speed.
•
If the signal is clipped, the automatic measurements cannot be made.
