Measurements
When enabled, the standard deviation shown in measurement statistics
becomes the standard deviation/mean.
7 To specify the number of values used when calculating measurement statistics,
press the Max Count softkey and enter the desired value.
Statistics are calculated on the most recent "N" number of values, where N is
the either the total number of acquisitions measured or a limited Max Count
number of acquisitions measured.
Other things to know about measurement statistics:
• When the
[Single] key is pressed, statistics are reset and a single measurement
is done (count = 1). Successive [Single] acquisitions accumulate statistical data
(and the count is incremented).
• The Increment Statistics softkey only appears when the acquisition is stopped
and the optional segmented memory feature is off. Press the [Single] or
[Run/Stop] key to stop the acquisition. You can use the horizontal position
control (in the Horizontal control section of the front panel) to pan through the
waveform. Active measurements will stay on screen, allowing you to measure
various aspects of the captured waveforms. Press Increment Statistics to add the
currently measured waveform to the collected statistical data.
• The Analyze Segments softkey only appears when the acquisition is stopped and
the optional segmented memory feature is on. After an acquisition has
completed (and the oscilloscope is stopped), you can press the Analyze
Segments softkey to accumulate measurement statistics for the acquired
segments.
You can also turn on infinite persistence (in the Display Menu) and press the
Analyze Segments softkey to create an infinite persistence display.
