Vbase voltage between flat base and ground (GND)
Overshoot
equals (Vmax - Vtop) / Vamp
Preshoot
equals (Vmin - Vbase) / Vamp
Vavg
the arithmetic average voltage value of complete measured signal,
or chosen part of measured signal
Vrms
true RMS voltage value over complete measured signal, or chosen
part of measured signal
automatic measurement options towards time measurement
10 options involved: Frequency (abbreviated as “Freq”), Period, Rise Time, Fall Time, +Width, -Width,
Delay 1→2 , Delay 1→2 , +Duty and -Duty.
Following illustration to assist better understanding different measurement options,
Definitions about these options -
Rise Time
the time span for signal amplitude rise from 10% to 90%, judged by the rising edge
of its first pulse
Fall Time
the time span for signal amplitude fall from 90% to 10%, judged by the falling edge
of its first pulse
+Width the pulse width that the first positive pulse at 50% amplitude point
-Width the pulse width that the first negative pulse at 50% amplitude point
Delay 1→2
the time delay of Channel 1 and Channel 2 at rising edge
Delay 1→2
the time delay of Channel 1 and Channel 2 at falling edge
+Duty measured by +Width / Period
-Duty measured by -Width / Period
vii. how to set sampling mode
From Function menu, via , enter into " Sampling " option.
