Product overview
The 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 5H-digit resolution. At 5H digits, the SourceMeter delivers 520
readings/second over the IEEE-488 bus. At 4H digits, it can read up to 2000 read-
ings/second into its internal buffer. See Appendix A for specifications.
Some additional capabilities of the SourceMeter include:
• 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 Ω 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 test-
ing.
• 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).
• Trigger-Link interface to Keithley Series 7000 switching hardware.
• Math expressions — Five built-in, up to five 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.
