The convention for bit assignment is as follows:
HP 16528/1653B
Front-Panel Reference
* (asterisk) indicates assigned bit
. (period) indicates unassigned bit
At power up the 16 bits of Pod 1 are assigned to the timing analyzer
and the 16 bits of Pod 5 are assigned to the state analyzer.
To change a bit assignment configuration., place the cursor on a bit
assignment field and press SELECT. You will see the following pop-up
menu.

Use the KNOB to move the cursor to an asterisk or a period and press
SELECT. The bit assignment toggles to the opposite state of what it
was before. When the bits (channels) are assigned as desired, place the
cursor on Done and press SELECT. This closes the pop-up and
displays the new bit assignment.
Assigning one channel per label may be handy in some applications.
This is illustrated in chapter 8 of the
Getting Started Guide. Also, you
can assign a channel to more than one label, but this usually isn't
desired.
Labels may have from
1
to 32 channels assigned to them. If you try to
assign more than 32 channels to a label, the logic analyzer will beep,
indicating an error, and a message will appear at the top of the screen
telling you that 32 channels per label is the maximum.
Channels assigned to a label are numbered from right to left by the
logic analyzer. The least significant assigned bit (LSB) on the far right
is numbered 0, the next assigned bit is numbered 1, and so on. Since 32
channels can be assigned to one label at most, the highest number that
can be given to a channel is 31.
