View
Any one of the three waveform displays the instrument provides: Main,
Mag1, and Mag2. Each view has its own graticule and time base. The
instrument always displays the Main view; the Mag1 and Mag2 views can be
added and removed from the display using the View buttons on the front
panel.
Virtual keyboard
A pop-up keyboard that lets you click to type characters for the control from

Waveform
The visible representation of an input signal or combination of signals.
Waveforms can be channel, reference, or math waveforms.
Waveform cursors
The cursor mode that presents two cursors you position to measure both the
time and amplitude parameters of a waveform record. The instrument
displays the time of both cursors with respect to the trigger and the time
between the cursors. The instrument also displays the value of both cursors
with respect to the waveform ground and between the cursors.
Waveform database
A collection of sequentially acquired waveforms.
Waveform types
Waveform types of the source to be measured can be Pulse, NRZ, and RZ.
Each waveform type has a measurement category (Amplitude, Timing, or
Area) that can be selected.
WfmDB
See Waveform database.
Windows OS
The underlying operating system on which this instrument runs.
YT format
The conventional display format. It shows the amplitude of a waveform
record (on the vertical axis) as it varies over time (on the horizontal axis).
