Diode Test
A test to verify polarity and measure the forward voltage drop of
a semiconductor junction.
Displacement Power Factor (DPF)
Cosine of the phase angle between fundamental components of
the voltage and current waveforms.
Display
The word used to refer to the screen or the LCD (liquid crystal
display).
Edge Trigger
Triggering that occurs when the oscilloscope detects the source
passing through a specified voltage level in a specified direction
(the trigger slope).
Envelope Acquisition Mode
A mode in which the oscilloscope acquires and displays a
waveform that shows the variation extremes of several
acquisitions.
External Trigger
Triggering that occurs when the oscilloscope detects the external
input signal passing through a specified voltage level in a
specified direction (the trigger slope).
Floating Measurements
Voltage measurements where the reference voltage is not earth
ground. The two oscilloscope inputs and the DMM input are
capable of taking independent floating measurements.
