Grid Indicators

These indicators appear around or on the grid to mark important points on the display. They are matched

to the color of the trace to which they apply. When multiple traces appear on the same grid, indicators

refer to the foreground trace—the one that appears on top of the others.

Trigger Time

, a small triangle along the bottom (horizontal) edge of the grid, shows the

time of the trigger. Unless Horizontal Delay is set, this indicator is at the zero (center) point

of the grid. Delay time is shown at the top right of the Timebase descriptor box.

Pre/Post-trigger Delay

, a small arrow to the bottom left or right of the grid, indicates that a

pre- or post-trigger Delay has shifted the Trigger Position indicator to a point in time not dis-

played on the grid. All Delay values are shown on the Timebase Descriptor Box.

Trigger Level

at the right edge of the grid tracks the trigger voltage level. If you change the

trigger level when in Stop trigger mode, or in Normal or Single mode without a valid trigger,

a hollow triangle of the same color appears at the new trigger level. The trigger level indic-

ator is not shown if the triggering channel is not displayed.

Zero Volts Level

is located at the left edge of the grid. One appears for each open trace on

the grid, sharing the number and color of the trace.

Cursor markers

appear over the grid to indicate specific voltage and time values on the

waveform. Drag-and-drop cursor markers to quickly reposition them.

Descriptor Boxes

Trace descriptor boxes appear just beneath the grid whenever a trace is turned on. They function to:

l Inform—descriptors summarize the current trace settings and its activity status.

l Navigate—touch the descriptor box once to activate the trace, a second time to open the trace setup

dialog.

l Configure—drag-and-drop descriptor boxes to change source or copy setups (with OneTouch).

Besides trace descriptor boxes, there are also Timebase and Trigger descriptor boxes summarizing the

acquisition settings shared by all channels, which also open the corresponding setup dialogs.

Channel Descriptor Box

Channel trace descriptor boxes correspond to analog signal inputs. They show

(clockwise from top left): Channel Number, Pre-processing list, Coupling, Vertical Scale

(gain) setting, Vertical Offset setting, Sweeps Count (when averaging), Vertical Cursor

positions, and Number of Segments (when in Sequence mode).

Codes are used to indicate pre-processing that has been applied to the input. The short

form is used when several processes are in effect.
