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).
