[volt-nuts] Keithley SourceMeters

[Brent Gordon]

Hello Fred,

Regarding your question on Keithley SourceMeters:

Short question, keithley makes source meters, They are in the micromeasurements handbook but I can not really place this. It sounds like a sort of IV meter, or coulomb meter but for DC. Not planning to buy one, just curious.


They are basically precision power supplies with precision measurement 
capabilities.  They are frequently used to test VCSELs (a type of laser 
diode) and LEDs.

Here is part of the description from 
<http://www.keithley.com/products/dcac/currentvoltage/gpmp?mn=2400>:

All SourceMeter models provide precision voltage and current sourcing as 
well as measurement capabilities. Each SourceMeter instrument is both a 
highly stable DC power source and a true instrument-grade 6½-digit 
multimeter.
