electrical signals such as waveforms.
Peak-to-Peak
The highest and lowest voltage value of a
waveform.
Percentage of Pulse Width
The ratio of signal on-time
to its total cycle time, as measured in percent.
Probe Calibration
A procedure that adjusts the
ScopeMeter test tool internally to compensate for
resistance variations between probes.
Probes
Measuring conductor that connects the
ScopeMeter test tool to a circuit; specifically for use in the
BNC jacks.
Pulse
A waveform that increases from a constant value,
then decreases to its original value.
Pulse Trains
A repetitive series of pulses.
Pulse Width
The duration from the beginning to the end
of a signal's on-time or off-time.
Range
The quantity between two points or levels.
Recall
The function of loading a stored Setup, Screen,
or Waveform back into the ScopeMeter test tool.
Recurrent
The ScopeMeter test tool continuously
(recurrently) updates the display. This gives a dynamic look
at the waveform activity as it occurs.
Repetitive Pulse
A signal with a regular pattern or
frequency.
Rise Time
The time between the 10% and 90% points
of the first slope after the left cursor of a waveform.
Rising Slope
The part of a waveform displaying a rise in
voltage.
Root Mean Square (RMS)
Conversion of AC voltages to
the effective DC value.
Roll
Visual log of a waveform activity that is useful when
measuring lower frequency signals.
RPM
Engine speed expressed in Revolutions Per
Minute.
Sample
A momentary reading taken from an input
signal. The ScopeMeter test tool takes a series of samples
to display a waveform.
Sampling Rate
The number of readings taken from a
signal every second. The ScopeMeter test tool can take up
to 25,000,000 samples per second.
Screen
The complete image of the display.
