Display
This section describes the front-panel display of the Model 708B and the bottom display of the Model
707B.
During operation, the display provides information about the selected channel, channel pattern,
channel state, and errors. You can press
DISPLAY
to cycle between the display of the channel or
pattern, the closed channel list, or a screen message.
During setup, the display shows menu choices that you can use to configure the instrument.
During operation, the display shows the control status (local or remote) and the current channel, and
indicates if any channels are closed. An example is shown below.
The control status is shown in the upper left corner of the display. If
REM
is displayed, the instrument
is being controlled remotely (through GPIB, LAN, or USB). If
REM
is not displayed, control is through
the front panel.

By default, the top line of the display shows the slot, row, and column of the selected channel.
