Math and Measure
Parameter Set Up
The Measure Dialog gives quick access to measurement features. Besides configuring parameters, use
the Measure dialog to show Statistics and Histicons, or to Gate measurements.
1. To open the Measure dialog, choose Measure > Measure Setup from the menu bar.
2. Check Show Table to display the measurement readout on screen.
3. For each parameter (Pn):
l Touch the Measurement field and choose a measurement from the list.
l Touch the Source field and choose the source trace to measure. This can be any type of input
available to your instrument; all will appear on the Source pop-up selector.
4. Enter any other measurement settings that appear.
Clear All Definitions resets all parameters to "None". Selections cannot be restored after clearing, you
must repeat parameter set up.
Statistics
Checking Statistics On adds the measures mean, min., max., sdev, and num(ber of measurements
computed) to the table.
For any parameter that computes on an entire waveform (like amplitude, mean, minimum, maximum,
etc.), the num statistic represents the number of sweeps.
For any parameter that computes on every event, the num statistic represents the number of events per
acquired waveform. If x waveforms were acquired, num is x times the number of cycles per waveform.
To reset the statistics counter, touch Clear Sweeps on the display or front panel.
Histicons
Histicons are miniature histograms of measurement parameters that appear on the measurement table.
These thumbnail histograms let you see at a glance the statistical distribution of each parameter. Select
the Histicons checkbox to turn on histicons.
