Similar descriptor boxes appear for zoom (Zx), math (Fx), and memory (Mx) traces. These descriptor
boxes show any Horizontal scaling that differs from the signal Timebase.

Digital Descriptor Box

Digital descriptor boxes appear whenever a digital line group is enabled on a mixed-
signal model oscilloscope. Like Channel descriptors, they are numbered 1-4
corresponding to one of the four line groups. They show the number of digital lines in
the group, the digital sample rate, and the digital memory.

Timebase Descriptor Box

The TimeBase descriptor box shows: (clockwise from top right) Trigger Delay
(position), Time/div, Sample Rate, Number of Samples, and Sampling Mode (blank
when in real-time mode).

Trigger Descriptor Box

Trigger descriptor box shows: (clockwise from top right) Trigger Source and Coupling,
Trigger Level (V), Slope, Trigger Type, Trigger Mode.

Setup information for Horizontal cursors, including the time between cursors and the
frequency, is shown beneath the TimeBase and

Trigger descriptor boxes. See the

Cursors

section for more information.
