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 amplitude.
RMS
Amplitude (voltage) measurement of the true Root Mean Square voltage.
Runt trigger
A mode in which the instrument 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.
Sample acquisition mode
The instrument creates a record point by saving the first sample during each
acquisition interval. That is the default mode of the acquisition.
Sample interval
The time interval between successive samples in a time base. For real-time
digitizers, the sample interval is the reciprocal of the sample rate. For
equivalent-time digitizers, the time interval between successive samples
represents equivalent time, not real time.
Sampling
The process of capturing an analog input, such as a voltage, at a discrete
point in time and holding it constant so that it can be quantized. Two general
methods of sampling are: real-time sampling and equivalent-time sampling.
Screen text
Lines displayed on screen that you use to indicate measurement reference
levels and points that an automatic measurement is using to derive the
measurement value.
Setting
The state of the front panel and system at a given time.
Setup control window
A group of related controls for a major instrument function that the
instrument displays across the bottom of the screen.
