Comma Separators
The function generator can display values on the front panel with or
without a comma separator. This feature is available only from the
front panel.

The display format is stored in non-volatile memory, and does not
change when power has been off or after a remote interface reset.
The comma separator is enabled when the function generator is
shipped from the factory.
Front-Panel Operation:
5: COMMA (SYS MENU)
See also “To turn off the comma separator,” on page 52.
Firmware Revision Query
The function generator has three microprocessors for control of various
internal systems. You can query the function generator to determine
which revision of firmware is installed for each microprocessor.
The function generator returns three numbers. The first number is
the firmware revision number for the main generator processor;
the second is for the input/output processor; and the third is for the
front-panel processor.
