   KEITHLEY 2440   Description / Specification:    
KEITHLEY 2440 42 V Source Meter w/ Measurements

The Keithley 2440 SourceMeter combines a precise, low-noise, highly stable DC power supply with a low-noise, highly repeatable, high-impedance multimeter. It has 0.012% basic accuracy with 5½-digit resolution. At 5½ digits, the SourceMeter delivers 520 readings/second over the IEEE-488 bus. At 4½ digits, it can read up to 2000 readings/second into its internal buffer. The unit has broad source and measurement ranges: Source voltage from 5µV to 42V; measure voltage from 1µV to 42V. Capabilities. Source current from 500pA to 5.25A; measure current from 100pA to 5.25A. Measure resistance from 10µohm (<10µohm in manual ohms) to 21.1Mohm. Maximum source power is 66W. Concurrent measurements of all three functions over the remote interface. Source-measure sweep capabilities (linear and logarithmic staircase sweeps, source sweep list of up to 2500 points, memory sweep of up to 100 instrument setups). 6-wire ohm measurement with programmable I-source or V-source with V or I clamp. 4-quadrant source and sink operation. Up to 12 stages of limit testing with a built-in comparator for pass/fail testing. Digital I/O for stand-alone binning operations or interface to component handler. Programming language and remote interfaces. The SourceMeter uses the SCPI programming language and two remote interface ports (IEEE-488/GPIB and RS-232C).

*This is a Web introductory price for one calibration of the KEITHLEY 2440. 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.
