To make additional voltage measurements
automatically
With the Measurement/Storage Module is installed, the following additional
automatic voltage measurements can be performed.
•
Vamplitude Amplitude Voltage measurement is made using the entire
waveform. When performing a measurement on a particular cycle, set the
controls to display only that cycle is displayed. The method used to
determine voltage amplitude is to measure Vtop and Vbase, then calculate
voltage amplitude as follows:
voltage amplitude = Vtop – Vbase
•
Vovershoot
A minimum of one edge must be displayed in order to perform
an Overshoot measurement. If more than one waveform, edge, or pulse is
present, the measurement is made on the first edge acquired. The method
used to determine overshoot is to make three different voltage
measurements, then calculate overshoot as follows:
percent overshoot =
Vmax–Vtop
Vtop–Vbase
x 100
•
Vpreshoot A minimum of one edge must be displayed in order to perform
a Preshoot measurement. If more than one waveform, edge, or pulse is
present, the measurement is made on the first edge acquired. The method
used to determine preshoot is to make three different voltage
measurements, then calculate preshoot as follows:
percent preshoot =
Vmin–Vbase
Vbase–Vtop
x 100
