384 InfiniiVision Oscilloscopes User’s Guide
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).
See page 137 for more information on Pattern triggering.
