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.
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.
