Picoammeter Voltage Source 5 1/2 Digits. Unit sold with a valid calibration certificate.

The Keithley 6487 Picoammeter Voltage Source improves on the measurement capability of the 6485 model, and adds a high resolution 500 V source.

It provides higher accuracy and faster rise times than the 6485, as well as a damping function for use with capacitive devices.
