The VI-700 Voltage and Current Source is a versatile precision dialable or remotely programmable voltage and current source. Its three ranges provide up to 20 V full scale (200 V with the HV option), and down to 100 mV resolution; and 20 mA full scale down to 0.1mA resolution. Both voltage and current outputs are available simultaneously. The output is set by a range selector and thumbwheel switches in the LOCAL mode, or by a digital input at the rear panel. The REMOTE mode control can be a RS232 or IEEE-488 interface.
