Product overview
The SourceMeter combines a precise, low-noise, highly stable DC power supply with a low-
noise, highly repeatable, high-impedance multimeter and a remote preamplifier for ultra low
current measurements. 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 210V; measure voltage from 1µV to 211V.
• Source current from 0.5fA to 105mA; measure current from 10aA to 105.5mA.
• Measure resistance from 100µΩ (<100µΩ in manual ohms) to 21.1TΩ.
• Maximum source power is 2.2W.
NOTE The Model 6430 is Y2K compliant.
Some additional capabilities of the SourceMeter include:
• Perform measurements at the DUT using the small Remote PreAmp.
• 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 1000 points, memory sweep of up to 100 instrument setups).
• 6-wire ohms measurement with programmable I-source or V-source with V or I clamp.
• 2.2W, 4-quadrant source and sink operation.
• Up to 11 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 pro-
gramming language and two remote interface ports (IEEE-488/GPIB and RS-232C).
• Trigger-Link interface to Keithley Series 7000 switching hardware.
• Math expressions — 5 built-in, up to 5 user-defined (bus only).
• Reading and setup storage — Up to 2500 readings and seven setups (five user defaults,
factory default, *RST default) can be stored and recalled.
• Closed-cover calibration — The instrument can be calibrated either from the front
panel or remote interface.
