Agilent 34980A  Multifunction Switch/Measure Unit *34980-90005*

3 Features and Functions
You can display a message on the front panel by sending a command
from the remote interface. The instrument can display up to 18
characters on the upper line of the front- panel display; any additional
characters are truncated (no error is generated). You can use letters
(A- Z), numbers (0- 9), and special characters like “@”, “%”, “*”, etc.
Use the “#” character to display a degree symbol ( ° ). Commas, periods,
and semicolons share a display space with the preceding character, and
are not considered individual characters.
While a message is displayed on the front panel, readings from a scan
or monitor are not sent to the front- panel display.
Sending a text message to the display overrides the display state;
this means that you can display a message even if the display is
turned off. In addition, pressing any front- panel key will clear the
text message.
Remote Interface Operation: The following command turns off the
front- panel display.
DISPLAY OFF
The following command displays a message on the front panel and turns
on the display if currently disabled (the quotes are not displayed).
DISPLAY:TEXT "SCANNING ..."
To clear the message displayed on the front panel (without changing the
display state), send the following command.
DISPLAY:TEXT:CLEAR
Front-Panel Number Format
The instrument can show numbers on the front- panel display with periods
or commas for the decimal point (radix) and thousands separator.
This feature is available from the front panel only.
The number format is stored in non- volatile memory, and does not
change when power has been off, after a Factory Reset (*RST
command), or after an Instrument Preset (SYSTem:PRESet command).
When shipped from the factory, a period is used as the radix character
and commas are used for the digits separator (e.g., +1.234,56 VDC).
