The Model 8200 is an extremely accurate microprocessor-based, remotely programmable, line-powered portable DC voltage/current standard. Transferring NIST reference values to instrumentation and equipment in the laboratory, the QA/QC department and on the production floor is convenient, fast and accurate.
Six decade controls allow adjustment of accurate, ultra-stable DC voltage ranges of ±100 mV, ±10V, and ±100V, in steps of 0.1 μV, 10 μV, and 100 μV respectively, with 10 ppm basic accuracy. If an even wider range is called for, a 1 kV option is available. The Model 8200 also provides outputs from ±1 μA to ±100 mA as a DC current source, with 100 ppm basic accuracy.
The 8200 offers microprocessor-assisted Incrematic™ control, allowing unlimited use of any one decade with full borrow/carry to and from all more significant decades for easier, faster, and more convenient manual operation. Measurements such as A/D linearity and monotonicity can be made at any chosen resolution, using only one knob. For additional convenience, the calibrator output automatically returns to zero whenever a new range or polarity is selected.
Well suited for automated test and calibration systems, the Model 8200 offers an optional rack mount kit, a rear terminal output, and IEEE-488 interface. Full automation is achieved by transmitting a simple character string for each new output setting, — an easier way to produce a long series of incremental changes in voltage or current. A fast 1 ms settling time, without troublesome overshoot, increases ATE throughput over other calibrators. The 8200 provides exceptional accuracy without special demands for recalibration or environmental control. It is stable to better than 20 ppm/6 months and 1 ppm/°C over a 0°C– 40°C range.
