Mask Field; Bit Editing Field - HP 1660CP Series User Manual

The Compare Menu

Mask field

Mask field
The channel masking field is used to specify a bit, or bits in each label that
you do not want compared. This causes the corresponding bits in all states to
be ignored in the comparison. The Reference data image itself remains
unchanged on the display.
When you select the Mask field an assignment pop-up appears in which you
specify which channels are to be compared and which channels are to be
masked. A "." (period) indicates a don't compare mask for that channel and
an "*" (asterisk) indicates that channel is to be compared.

Bit Editing field

The bit editing fields are located in the center of the Reference listing
display. A bit editing field exists for every label in the display unless the
label's base is ASCII or inverse assembled symbols. The bit editing field lets
you modify the values of individual bits in the Reference image or specify
them as don't compare bits.
You access data in the Reference listing by rolling the data listing using the
knob until the data is located in the bit editing field. To enter a desired
pattern or don't compare (X) for a bit, select the field and use the front-panel
keypad.
