   KEITHLEY 2425   Description / Specification:    
KEITHLEY 2425 105 V Source Meter w/ Measurements

The Keithley 2425 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 105V; measure voltage from 1µV to 105V. Capabilities. Source DC or pulse voltage from 5µV to 105V; measure voltage from 1µV to 105.5V. Source DC current from 500pA to 3.15A; measure DC current from 100pA to 3.165A. Source pulse current from 500pA to 10.5A. Measure resistance from 10µohm (<10µohm in manual ohms) to 21.1Mohm. Maximum DC source power is 110W. 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 2425. 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.

Clipping is the limiting of a signal so that it never exceeds some threshold.

Line Regulation
Line regulation is the capability to maintain a constant output voltage level on the output channel of a power supply despite changes to the input voltage level.

Peak Envelope Power
Peak envelope power is the maximum value of the envelope power. Envelope power is measured by making the averaging time much less than 1/fm where fm is the maximum frequency component of the modulation waveform. The averaging time is therefore limited on both ends: (1) it must be small compared to the period of the highest modulation frequency, and (2) it must be large enough to be many RF cycles long.

RMS or root mean square is a statistical measure of the magnitude of a varying quantity
