Positive width
A timing measurement of the distance (time) between two amplitude
points—rising-edge
MidRef (default 50%) and falling-edge MidRef
(default 50%)—on a positive pulse.
Posttrigger
The specified portion of the waveform record that contains data
acquired after the trigger event.
Pretrigger
The specified portion of the waveform record that contains data
acquired before the trigger event.
Probe
An oscilloscope input device.
Probe compensation
Adjustment that improves low-frequency response of a probe.
Pulse trigger
A trigger mode in which triggering occurs if the oscilloscope finds a
pulse, of the specified polarity, with a width between, or optionally
outside, the user-specified lower and upper time limits.
Quantizing
The process of converting an analog input that has been sampled,
such as a voltage, to a digital value.
Real-time sampling
A sampling mode where the oscilloscope samples fast enough to
completely fill a waveform record from a single trigger event. Use
real-time sampling to capture single-shot or transient events.
Record length
The specified number of samples in a waveform.
Reference memory
Memory in an oscilloscope used to store waveforms or settings. You
can use that waveform data later for processing. The oscilloscope
saves the data even when the oscilloscope is turned off or unplugged.
Rise time
The time it takes for a leading edge of a pulse to rise from a
LowRef
value (typically 10%) to a
HighRef value (typically 90%) of its ampli-
tude.
RMS
Amplitude (voltage) measurement of the true Root Mean Square
voltage.
Runt trigger
A mode in which the oscilloscope triggers on a runt. A runt is a pulse
that crosses one threshold but fails to cross a second threshold
before recrossing the first. The crossings detected can be positive,
negative, or either.
