Digital Channels
If a channel waveform is repositioned over another channel waveform,
the indicator at the left edge of the trace will change from
D nn
designation (where nn is a one or two digit channel number) to
D
*. The
"*" indicates that multiple channels are overlaid.
To display digital channels as a bus
Digital channels may be grouped and displayed as a bus, with each bus
value displayed at the bottom of the display in hex or binary. You can
create up to two buses. To configure and display each bus, press the
[Digital] key on the front panel. Then press the Bus softkey.
Next, select a bus. Rotate the Entry knob, then press the Entry knob or
the
Bus1/Bus2 softkey to switch it on.
Use the
Channel
softkey and the Entry knob to select individual channels
to be included in the bus. You can rotate the Entry knob and push it or
push the softkey to select channels. You can also press the
Select/Deselect
D15-D8
and
Select/Deselect D7-D0
softkeys to include or exclude groups of
eight channels in each bus.
If the bus display is blank, completely white, or if the display includes "...",
you need to expand the horizontal scale to allow space for the data to be
shown, or use the cursors to display the values (see
"Using cursors to read
bus values" on page 133).
The Base softkey lets you choose to display the bus values in hex or
binary.
The buses are shown at the bottom of the display.
