Description

Both the Agilent 66312A Dynamic Measurement DC Source and the Agilent 6611C, 6612C, 6613C and

6614C System DC Power Supplies combine two instruments in one unit. They include 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 66312A

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 66312A only).

16-bit measurement resolution (low range accurate down to 2 microamperes).

Triggered acquisition of digitized current and voltage waveforms (Agilent 66312A 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 with SCPI command language.

♦ 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, all units are set to the SCPI programming language. The language setting

is saved in non-volatile memory.

To change the programming language from SCPI to Compatibility language, press the

front panel

Address key, use ô to scroll to the LANG command, press

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

power supplies (refer to appendix D in the the Programming Guide). Dc source status registers allow

remote monitoring of a wide variety of dc source operating conditions.
