Making automatic measurements

Quick Meas makes automatic measurements on any channel source or any running math function. The results of the last three measurements selected are displayed on the dedicated line above the softkeys, or in the display area when some menus are selected. Quick Meas also makes measurements on stopped waveforms when you are panning and zooming.

Cursors are turned on to show the portion of the waveform being measured for the most recently selected measurement (right-most on the measurement line).

2Press the Source softkey to select the channel or running math function on which the quick measurements will be made.

Only channels or math functions that are displayed are available for measurements. If you choose an invalid source channel for a measurement, the measurement will default to the nearest in the list that makes the source valid.

If a portion of the waveform required for a measurement is not displayed or does not display enough resolution to make the measurement, the result will display “No Edges”, “Clipped”, “Low Signal”, “< value”, or “> value”, or a similar message to indicate that the measurement may not be reliable.

3Press the Clear Meas softkey to stop making measurements and to erase the measurement results from the display line above the softkeys.

When Quick Meas is pressed again, the default measurements will be Frequency and Peak-Peak.

4Press the Select softkey then rotate the Entry knob to select a measurement to be made.

5The Settings softkey will be available to make additional measurement settings on some measurements.

6 Press the Measure softkey to make the measurement.
