DC Current and Voltage Calibrator * 5 Current ranges from 100uA to 1A * 4 Voltage ranges from 10mV to 10V * 0.01% Accuracy * 30% Overrange on all ranges * IEEE/GPIB compatible Time Electronics Limited, Botany Industrial Estate, Tonbridge, Kent, TN9 1RH Telephone: 01732 355993 Fax: 01732 770312 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. V3 09/09/03
Type: IEEE 488 Connections: 24 pin connector as prescribed in the 488– 1975 standard Addressing: rear panel switch. Device No. 0-31 Isolation: All outputs electrically isolat ed from IEEE bus (Up to 350V A.C.) Overload: If the instrument fails to give the correct output due to internal fault conditions, or output overloads, the mircroprocesso r resets the output to zero within 10ms and an ‘OUTPUT ERROR’ message is displayed. Output Polarity: The true Bipolar output can provide positive or negative polarity. Local Controls & Displays: LED indicators: indicate operation mode. 7 digit LED displays output and polarity. Push buttons select and indicate range and output polarity. Setting Time: Less than 1ms between 0 and full scale. Less than 50ms with range change. Output Connections: Front panels – 4mm ‘Banana’ low thermal E.M.F.
