An acquisition mode useful at slow horizontal scale settings.
Roll mode allows you to view the waveform as it is acquired
point-by-point. The waveform appears to roll across the display.
RS-232
The serial communication port used to connect to a hard-copy
device, computer, controller, or terminal.
Sample Acquisition Mode
A mode in which the oscilloscope creates a record point by
saving the first sample during each acquisition interval. This is
the default mode of the acquisition system.
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.
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.
Scope QuickMenu
A built-in QuickMenu that places the most commonly used
oscilloscope controls around the screen. With the Scope
QuickMenu, you may not need to use the main menu system to
operate the oscilloscope.
