   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.

dBc
dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Load Regulation
Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Settling Time
Settling time of an output device is the time elapsed from the application of an ideal instantaneous step input to the time at which the amplifier output has entered and remained within a specified error band, usually symmetrical about the final value.
