Probe
An input device.
Probe compensation
Adjustment that improves low-frequency response of a probe.
Proximal
The point closest to a reference point. As used in the instrument, the
beginning measurement point for timing measurements.
Pulse trigger
A trigger mode in which triggering occurs if the instrument 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 instrument 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.
Recovered Clock
A clock signal derived from and synchronous with a received data sequence.
Reference memory
Memory in an instrument used to store waveforms or settings. You can use
that waveform data later for processing. The instrument saves the data even
when the instrument is turned off or unplugged.
Reference Waveforms
Waveforms that are static, not live (see live waveforms). Reference
waveforms are channel or math waveforms that you save to references. Once
saved, they do not update.
