Front Panel/Remote Operation
The front panel has both rotary (RPG) and keypad controls for setting the output voltage and frequency.
The panel display provides digital readouts of a number of output measurements. Annunciators display
the operating status of the ac source. System keys let you perform system functions such as setting the
GPIB address and recalling operating states. Front panel Function keys access the ac source function
menus. Front panel Entry keys let you select and enter parameter values. Refer to Chapter 4 for a
complete description of the front panel controls.
Remotely programming is accomplished from either the GPIB bus or from an RS-232 serial port. GPIB
and RS-232 programming uses SCPI commands (Standard Commands for Programmable Instruments)
that make the ac source programs compatible with those of other instruments. AC source status registers
permit remote monitoring of a wide variety of ac source operating conditions
NOTE: Refer to the ac source Programming Guide for further information about remotely
programming the ac source. If you are using the Agilent 6843A, refer to the appropriate
Regulatory Test Solution User’s Guide for information about regulatory testing.
Output Characteristic
Ranges
The ac source’s output characteristic is shown in the following figure. The output voltage of the ac
source may be adjusted to any value within the range of the unit. On three-phase units, each phase can be
adjusted independently of the other two.
Rated output VA and conversion efficiency is greatest when the output voltage is set near maximum. For
this reason, the ac source is designed to operate on one of two ranges: 150 volts full-scale, or 300 volts
full-scale. You should choose the range that allows you to operate nearest the full-scale output capability
of the selected range.
