The Keithley 230 Programmable Voltage Source incorporates a 100-step, programmable memory buffer, useful in applications where either a fixed number of outputs is repeated or a complex waveform of discrete steps must be generated. It has a ±50µV to ±101VDC programmable output. Up to ±100mA programmable current limit. Up to 4 1/2 digit resolution. GPIB.The Programmable Voltage Source has a voltage range from 199.95mVDC to 101VDC with three selectable current limits allowing the user to tailor the current limit from 2mA to 20mA to 100mA. It can be used with any measurement system that uses the IEEE-488 interface bus. Specifications. Maximum current limit: ±100mA (–0, +20%). Selectable current limit: ±100mA, ±20mA, ±2mA (–0, +20%). line regulation: <0.01% for AC power line changes within specified limits. Noise: (150µV + 50ppm range) p-p, 0.1Hz to 300Hz; 5mV p-p, 0.1Hz to 300kHz. Specification applies for local sensing only, typical. Response time: <3ms to within 0.1% of programmed change for Current Limit of at least 20mA. Transient recovery time: <3ms to rated accuracy for Current Limit of at least 20mA.
