6487 – Picoammeter/Voltage Source with 5½-digit resolution

The 5½-digit 6487 Picoammeter/Voltage Source improves on the measurement capability of the award-winning 6485, 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. With eight current measurement ranges and high speed autoranging, this cost-effective instrument can measure currents from 20 fA to 20 mA, take measurements at speeds up to 1000 readings per second, and source voltage from 200 µV to 505 V. The 6487’s 10 fA resolution, superior sensitivity,
voltage sweeping, and Alternating Voltage resistance measurements make it well suited for characterizing low current devices. Using the latest current measurement technology, it is significantly less expensive than other instruments that perform similar functions, such as
optical power meters, tera-ohmmeters, competitive picoammeters, or user-designed solutions. With a price that’s comparable to a high-end DMM, the 6487 makes picoamp-level measurements affordable for virtually any laboratory or production floor.
