Among them, xi is the measurement result of the i-th point, and n is the number of
measured points.
10. Root Mean Square [Vrms]: The root mean square value over the entire waveform or
gated area.

12. Overshoot: The ratio of the difference between the maximum value of the waveform
and the top value to the amplitude.
13. Pre-shoot: The ratio of the difference between the minimum value and the bottom
value of the waveform to the amplitude.
14. Fall Overshoot: The ratio of the difference between the maximum value and the top
value of the waveform to the amplitude.
15. Rise Pre-shoot: The ratio of the difference between the minimum value of the wave-
form and the bottom value to the amplitude.
16. Variance: The average of the sum of the squares of the difference between the am-
plitude value of each waveform point and the average value of the waveform over the
entire waveform or gated area. The variance reflects the degree of fluctuation of the
waveform. Calculated as follows:

All measurements
Press Meas on the front panel to enter the measurement setting interface. Press [All
Measurements] to measure 42 waveform parameters with one key. The measurement
results are displayed at the bottom of the screen, and the color markers consistent with
the current measurement channel are displayed.
Note: If the measurement display is "

source has no signal input, or the measurement result is not within the valid range (too
