Description
Both the Agilent 66332A Dynamic Measurement DC Source and the Agilent
6631B/6632B/6633B/6634B System DC Power Supply combine two instruments in one unit. It includes
a dc source, which produces dc output with programmable voltage and current amplitude, and a highly
accurate voltage and current meter, with the capability to measure very low-level currents. Additionally,
the Agilent 66332A Dynamic Measurement DC Source has the ability to measure and characterize output
voltage and current of pulse or ac waveforms.
Capabilities
♦ Output Voltage and Current control with 12-bit programming resolution
♦ Extensive measurement capability:
dc voltage and current.
rms and peak voltage and current (Agilent 66332A only).
16-bit measurement resolution (low range accurate down to 2 microamperes).
Triggered acquisition of digitized current and voltage waveforms (Agilent 66332A only).
♦ Front panel control with 14-character vacuum fluorescent display, keypad, and rotary control for
voltage and current settings.
♦ Built-in GPIB and RS-232 interface programming with SCPI command language.
♦ Non-volatile state storage and recall.
♦ Over-voltage, over-current, over-temperature, and RI/DFI protection features.
♦ Extensive selftest, status reporting, and software calibration.
Front Panel Controls
The front panel has both rotary (RPG) and keypad controls for setting the output voltage and current. The
panel display provides digital readouts of a number of output measurements. Annunciators display the
operating status of the dc source. System keys let you perform system functions such as setting the GPIB
address and recalling operating states. Front panel Function keys access the dc source function menus.
Front panel Entry keys let you select and enter parameter values. Refer to chapter 5 for a complete
description of the front panel controls.
Remote Programming
NOTE: When shipped, Agilent 6631B/6632B/6633B/6634B units are set to the Compatibility
programming language; Agilent 66332A units are set to the SCPI programming
language.
To change the programming language from Compatibility to SCPI, press the front panel
Address key, use ô to scroll to the LANG command, press
Ì
to select SCPI, then
press
Enter. Refer to the Programming Guide supplied with your dc source for further
information about remote programming.
The dc source may be remotely programmed via the GPIB bus and/or from an RS-232 serial port. GPIB
programming is with SCPI commands (Standard Commands for Programmable Instruments), which make
the dc source programs compatible with those of other GPIB instruments. Compatibility commands are
also included to make the dc source compatible with the Agilent 6632A, 6633A, and 6634A Series dc
