   KEITHLEY 220   Description / Specification:    
KEITHLEY 220 Programmable Current Source

The Keithley 220 Programmable Current 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. In system applications, the buffer can be loaded through the bus and the 220 can be commanded to sequence through memory while the controller is busy on other tasks. The TRIGGER IN /OUT feature, when used in the STEP mode, allows the source to synchronize the measurements of other instruments. The TRIGGER OUT occurs after the completion of dwell time; TRIGGER IN causes the 220 to advance to its next program step. Four TTL-compatible input and output (I /O) lines are provided on each model to receive and generate system commands. Ranges 1nA to 100mA, full range current from ±1.9995 nA to ±101.00 mA. Step Size 50 uA to 500 fA. Incorporates a selectable voltage compliance of up to 105 V in 1 V increments. The 100 memory locations allow up to 100 storage points for programming source, V-limit, and dwell time. Can be used with any measurement system that uses the IEEE-488 interface bus or operated via the front-panel.

*This is a Web introductory price for one calibration of the KEITHLEY 220. 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.

Available Gain
Available Gain is the ratio, at a specific frequency, of power available from the output to the power in from the source.

Decibel (dB)
A unit of measurement of power which indicates relative power. A -10 dB means a reduction in power by 10 times, -20 dB means another 10 times or 100 times overall, -30 means another 10 times or 1000 times overall and so on.

Mismatch Uncertainty
Mismatch Uncertainty is caused by re-reflections between one device (the source) and the device that follows it (the load).

Pulse Power
Pulse Power, the energy transfer rate is averaged over the pulse width. Pulse width is considered to be the time between the 50 percent risetime/falltime amplitude points. Pulse power averages out any aberrations in the pulse envelope such as overshoot or ringing.
