KEITHLEY 230 Programmable Voltage Source

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.

*This is a Web introductory price for one calibration of the KEITHLEY 230. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Channel Bandwidth
Channel Bandwidth is the bandwidth over which power is measured. This is usually the bandwidth in which almost all of the power of a signal is contained.

Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

Overshoot is the distortion that follows a major transition; the difference between the peak power point and the pulse-top amplitude computed as a percentage of the pulse-top amplitude.

Rise Time
Rise time refers to the time required for a signal to change from a specified low value to a specified high value, usually 10 and 90 percent of pulse-top amplitude (vertical display is linear power).
