An DIN keyboard can be connected to the DIN connector on the rear
panel of the analyzer. The DIN keyboard provides an easier way to
enter characters for the le names, display titles, and Instrument
BASIC programs. It can also access the analyzer softkey functions
by using keyboard function keys. For more information on the DIN
keyboard, see the HP Instrument BASIC Manual Supplement .
