Mean plus or minus 3 StdDev
The percentage of points in the histogram that are within three standard deviations of the histogram mean.
Minimum
This voltage measurement is the minimum amplitude. It is typically the most negative peak voltage and is measured over the
entire waveform or gated region.
Peak hits
Displays the number of points in the largest bin of the histogram.
Pk-Pk
Displays the peak-to-peak value of the histogram.
■ Vertical histograms display the "voltage" of the highest nonzero bin minus the "voltage" of the lowest nonzero bin.
■ Horizontal histograms display the "time" of the right-most nonzero bin minus the "time" of the left-most nonzero bin.
StdDev (standard deviation)
The standard deviation (Root Mean Square deviation) of all acquired points within or on the histogram box.
Waveform count
Displays the number of waveforms that have contributed to the histogram.
Median
The middle point of the histogram box. Half of all acquired points within or on the histogram box are less than this value and half
are greater than this value.
Set the horizontal delay
Use the Horizontal Delay Mode control to enter the amount of horizontal delay.
1. Click the Horizontal Delay Mode button to set the horizontal delay to on.
2. Click in the Acquisition Delay entry box and use the multipurpose knob to enter a value.
NOTE. You can also enter a delay value with the front-panel Horizontal Position knob.
Set the horizontal position
Use the Horizontal Position control to move the trigger point within the acquired waveform.
■ To acquire waveform data only after the trigger event, set the Horizontal Position control to zero.
■ To acquire waveform data leading up to the trigger event, set the Horizontal Position control to any value greater than zero.
■ For some setup control windows, you can click in the position control entry box and use the multipurpose to enter a value (in
addition to using the front-panel Horizontal Position knob).
