Display Control
For security reasons, or to speed up the rate at which the function
generator can execute commands from the remote interface, you may
want to turn off the front-panel display. From the remote interface,
you can also display a 12-character message on the front panel.
• You can only disable the front-panel display by sending a command
from the remote interface (you cannot disable the front panel while in
local operation).
• When disabled, the front-panel display is blanked (however, the bulb
used to backlight the display remains enabled). All keys except
are locked out when the display is disabled.
•
Sending a message to the front-panel display from the remote interface
overrides the display state. This means that you can display a
message even if the display is currently disabled (remote interface
errors are always displayed even if the display is disabled).
• The display is automatically enabled when power is cycled, after an
instrument reset (*RST command), or when you return to local
(front panel) operation. Press the key or execute the IEEE-488
GTL (Go To Local) command from the remote interface to return to
the local state.
• The display state is saved when you store the instrument state using
*SAV command. When you recall the instrument state using *RCL
command, the front-panel display will return to the previous state.
• You can display a text message on the front panel by sending a
command from the remote interface. You can use upper- or lower-case
letters (A-Z), numbers (0-9), and any other character on a standard
computer keyboard. Depending on the number of characters that you
specify, the function generator will choose one of two font sizes to
display the message. You can display approximately 12 characters in
a large font and approximately 40 characters in a small font.
