   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.

Average Power
Average power means that the energy transfer rate is to be averaged over many periods of the lowest frequency involved. For a CW signal, the lowest frequency and highest frequency are the same, so average power and power are the same. For an amplitude modulated wave, the power must be averaged over many periods of the modulation component of the signal as well.

Dynamic range
Dynamic range the ratio of a specified maximum level of a parameter, such as power, current, voltage or frequency, to the minimum detectable value of that parameter.

Modulation
Modulation is the process by which the characteristic of one wave (the carrier) is modified by another.

Repeatability
Repeatability is the variation in a number of repeated measured quantities when measurement conditions are changed and restored. The value corresponds to half the spread between the minimum and maximum value measured.
