Using the Front-Panel Interface
Front-Panel Controls
Run/Rep Key
The Run key starts a data acquisition in any run mode you specify. After the
acquisition, the analyzer (state or timing) is automatically forced into the last
display menu accessed.
To start a single run, press the Run/Rep key. To start a Repetitive run, press
the blue shift key, then press the Run/Rep key.
Stop key
The Stop key allows you to stop data acquisition or printing. After the
acquisition is stopped, the data displayed onscreen depends on which run
mode (single or repetitive) was used to acquire the data. In the repetitive
mode, Stop halts acquisition after the last completed single acquisition cycle.
In single mode, Stop causes the single data acquisition to be aborted and
partial data is displayed. If you print a hard copy, the Stop key stops the print.
Print/All Key
The Print/All key starts a hard copy print of the screen and any data that
appears on that screen. To print all data that is offscreen, press the blue shift
key prior to pressing the Print/All key.
Don't Care Key
The Don't Care key allows you to enter don't cares (Xs) in binary, octal, and
hexadecimal pattern assignment fields. In Alpha Entry fields, this key enters
a space and moves the underscore marker to the next space.
Clear Entry Key
The Clear entry key allows you to clear assignment fields of alpha entries,
channel assignments, and numeric entries. When you press the Clear entry
key in an alpha assignment field, a cursor appears that indicates the start
point for new alpha entry.

channel assignment, or enter a period in an alpha assignment.
