Hex Bus Pattern Triggering
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 122 for details. You can trigger on a bus value whether you
are displaying the bus or not.
To trigger on a bus value:
1Press the Pattern key on the front panel.
2Press the Channel softkey and rotate the Entry knob to select
Bus1 or Bus2.
3Press the Digit softkey and rotate the Entry knob to select a
digit of the selected bus.
4Press the Hex softkey and rotate the Entry knob to select a
value for the digit.
5You can use the Set all Digits softkey to set all digits to a
particular value.
When a hex bus digit contains one or more don’t care (X) bits
and one or more bit 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 125.
NOTE If a digit is made up of less than four bits, then the value of the digit will be
limited to the value that can be created by the selected bits.
