The Keithley 6430 is a sensitive sourcemeter that provides a sensitive bi-directional amplifier with sensitive feedback elements for measuring or sourcing currents at the device being tested. 6430 models generate voltage, current, and resistance measurements at surprising speeds. The 6430 can read up to 2000 source measure readings per second into the unit's internal memory. The high-level signal outputs by the 6430 Remote Preamp are sent to the controlling mainframe via a two-meter cable. This allows the user to make a direct or very short connection to the signal, minimizing the effects of cable noise. Model 6430 is designed with an IEEE-488 bus output and can transmit up to 75 source/measure readings per second to an external computer controller, including pass/fail indication.
