Specifying Patterns - HP 1652B Getting Started Manual

Note
If you don't see any bit assignment fields, it merely means you do not
have any pods assigned to this analyzer. Either switch analyzers or
assign a pod to the analyzer you are working with.
-
To assign bits in these menus, place the cursor on one of the bit
assignment fields and press SELECT. You will see the following pop-
up menu:
I
15
87
, , , * ' a I ,
********
Figure 3-l 1. Bit Assignment Pop-up
Place the cursor on the left-most asterisk or period in the pop-up that
you want to change and press SELECT. The bit assignment toggles to
the opposite state of what it was when the pop-up first opened. Move
the cursor one bit to the right. Holding the SELECT key, repeats the
bit assignment. You close the pop-up by placing the cursor on Done
and pressing SELECT.
SpeCifying
The Specify Patterns fields appear in several menus in both the timing
Patterns and state analyzers. Patterns can be specified in one of the available
number bases, except ASCII.
The convention for "don't cares" in these menus is an "X" except in the
decimal base. If the base is set to decimal after a "don't care" is
specified, a $ character is displayed.
An example of a Specify Patterns field is the Find Pattern
the Timing Trace Specification menu.
