Digital Channels
When you press the [Digital] key to display the Digital Channel Menu, the digital
activity indicator is shown where the cursor values were and the bus values at the
cursors are displayed in the graticule.
Bus values are
displayed when
using Pattern
trigger
The bus values are also displayed when using the Pattern trigger function. Press
the [Pattern] key on the front panel to display the Pattern Trigger Menu and the bus
values will be displayed on the right, above the softkeys.
The dollar sign ($) will be displayed in the bus value when the bus value cannot be
displayed as a hex value. This occurs when one or more "don't cares" (X) are
combined with low (0) and high (1) logic levels in the pattern specification, or
when a transition indicator — rising edge ( ) or falling edge ( ) — are included in
the pattern specification. A byte that consists of all don't cares (X) will be
displayed in the bus as a don't care (X).
