Hex Bus Pattern Trigger
You can specify a bus value on which to trigger. To do this, first define the bus. See
"To display digital channels as a bus" on page 110 for details. You can trigger on
a bus value whether you are displaying the bus or not.
To trigger on a bus value:
1 Select the Pattern trigger type and the Entered qualifier as described in
"Pattern
Trigger"
on page 141.
2 In the Bus1 or Bus2 fields, enter the hex character values.
When a hex bus digit contains one or more don't care (X) bits and one or more bits
with a value or 0 or 1, the "$" sign will be displayed for the digit.
For information regarding digital bus display when Pattern triggering see
"Bus
values are displayed when using Pattern trigger" on page 112.
If a digit is made up of less than four bits, the value of the digit is limited to the greatest
number that can be represented by the number of bits.
