Measuring with Parameters
Overview
Parameters are pre-programmed measurements that eliminate the need to
set up cursors for standardized measurements, like rise time, fall time,
peak-peak amplitude, etc. Use them to automatically calculate many
attributes of your waveform. You can make common measurements on
one or more waveforms, and display up to six parameter measurements at
one time. You can also display statistics for your measurements, or apply
gating to the measurement area.
The WaveSurfer MXs-B oscilloscope uses pre-defined algorithms to
determine the top, base, 10% level, etc. of the waveform in order to make
automatic measurements. These algorithms are in accordance with IEEE
standards.
If, for some reason, a parameter is unable to be calculated correctly, a
warning symbol is shown underneath the measurement. This indicates to
proceed with caution.
In the WaveSurfer MXs-B oscilloscope, some parameter measurements
(like Mean) produce a single value for all the data between the measure
gates. Others (like Rise Time) are always calculated for every value in an
acquisition. However, the value displayed is always the last value in the
acquisition. Use statistics if you desire more information about the
distribution of measurements in the acquisition.
Setting Up Parameter(s)
1. Press the Measure front panel button
Or, select Measure  Measure Setup from the menu bar.
The following dialog is then shown on the lower display.
