The 9818 is a high performance IEEE programma-

ble D.C. Current/Voltage Calibration source. By

combining microprocessor and linear circuit tech-

nology, exceptional long term stability has been

achieved. Computer selection of the basic refer-

ence device combined with high performance pre-

cision resistors ensure a guaranteed 50 ppm per

year stability.

Up to 10V D.C. or 1 Amp D.C. may be supplied by

the unit with a 5 ppm resolution. The deviation

control allows easy percentage deviation from the

nominal value.

Range and output value selection is by keyboard

entry and the value is clearly displayed on the 7

digit L.E.D. display.

Introduction

The modular construction is based on the standard

Euro Card frame. Each main section i.e. Microproc-

essor Control, IEEE interface, D-A Converter, Refer-

ence Amplifier etc. is located on a separate plug in

the Euro board. All boards are easily accessible

from the instrument rear.

With the ability to be operated manually and via the

IEEE bus, the 9818 is ideal for ATE systems or for

D.C. signal generation.
