2 – General Information

Description

Both the HP 66332A Dynamic Measurement DC Source and the HP 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 HP 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 (HP 66332A only).

16-bit measurement resolution (low range accurate down to 2 microamperes). Triggered acquisition of digitized current and voltage waveforms (HP 66332A

only).

Front panel control with 14-character vacuum fluorescent display, keypad, and rotary control for voltage and current settings.

Built-in HP-IB 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 HP-IB 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, HP 6631B/6632B/6633B/6634B units are set to the Compatibility programming language; HP 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 to scroll to the LANG command, press Ãto 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 HP-IB bus and/or from an RS-232 serial port. HP-IB programming is with SCPI commands (Standard Commands for Programmable Instruments), which make the dc source programs compatible with those of other HP-IB instruments. Compatibility commands are also included to make the dc source compatible with
