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 can not be displayed as a hex value. This occurs when
one or more “don’t cares” (X) are combined with high (H) and
low (L) 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).
See page 143 for more information on Pattern triggering.
