SECTION 3 - OPERATION
3.1 GENERAL
This section explains how to operate the BHK-MG Power Supply. The power supply can be
operated either in Local mode using the front panel keypad and LCD (PAR. 3.2), or in Remote
mode using either SCPI commands via the GPIB bus (PARs. 3.3, 3.5) or analog programming
via the rear panel terminals (PAR 3.6). Remote analog programming can be combined with
either local programming using the front panel keyboard or remote programming using SCPI
commands via the GPIB bus.
3.2 LOCAL MODE OPERATION
Local operation of the BHK-MG Power Supply is accomplished via the 24 key keypad on the
front panel. All indications are provided by the 2-line LCD. Local mode operation includes a
description of the interaction between the LCD and the front panel keypad. Each key of the front
panel is described, with a reference to a paragraph detailing the use of that key.
3.2.1 FRONT PANEL KEYPAD AND LCD. (SEE FIGURE 2-1)
The front panel keypad is comprised of 24 keys, 13 dedicated to command functions, five dedi-
cated to data functions, and six keys that have both command and data functions. When the
power supply is in command entry status the command functions are effective; when the power
supply is in data entry status the data functions are effective.

rent at the output terminals. When the output is disabled (LCD bottom line reads Output OFF),
the power supply is in Command entry status even though the blinking colon is not visible.
