Ix Innovations has released the PocketPico picoammeter, which features a DC current measuring range of 20 pA to 2 mA with out range switching. It also features a USB interface for convenient integration with computer-based instrumentation systems. The PocketPico uses a patent pending technology called SafeRanging – a continuous ranging technique that Ix says is superior to the conventional relay-based autoranging technology used in other picoammeters.
The PocketPico SafeRanging method uses log compression and a current sink circuit topology to obtain accurate readings and avoid the need for individual measurement ranges. This yields fast readings (15,000 samples per second) over several decades of current without the drawbacks associated with conventional autoranging.
The PocketPico can be used for testing and characterising a wide variety of objects, including optoelectronics, sensors and nanomaterials. The PocketPico firmware is designed to enable users to replace their existing picoammeters with the PocketPico for use with existing test setups. It accepts basic Standard Commands for Programmable Instrumentation (SCPI) for use with MATLAB, LabView and custom scripts.
