How to Implement the Automatic Measurement
With the
Measure
button pressed down, an automatic measurement can be
implemented. There are 20 types of measurements and 4 measurement results can be
displayed simultaneously.
Term interpretation
：
Vpp:
Peak-to-Peak Voltage.
Vmax:
The maximum amplitude. The most positive peak voltage measured over the
entire waveform.
Vmin:
The minimum amplitude. The most negative peak voltage measured over the
entire waveform.
Vamp:
Voltage between Vtop and Vbase of a waveform
Vtop:
Voltage of the waveform’s flat top, useful for square/pulse waveforms.
Vbase:
Voltage of the waveform’s flat base, useful for square/pulse waveforms.
Overshoot:
Defined as (Vmax-Vtop)/Vamp, useful for square and pulse waveforms.
Preshoot:
Defined as (Vmin-Vbase)/Vamp, useful for square and pulse waveforms.
Average:
The arithmetic mean over the entire waveform.
Vrms:
The true Root Mean Square voltage over the entire waveform.
Rise Time:
Time that the leading edge of the first pulse in the waveform takes to rise
from 10% to 90% of its amplitude.
Fall Time:
Time that the falling edge of the first pulse in the waveform takes to fall
from 90% to 10% of its amplitude.
+Width:
The width of the first positive pulse in 50% amplitude points.
-Width:
The width of the first negative pulse in the 50% amplitude points.

2 :
The delay between the two channels at the rising edge.
