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.
