Pico - FLEX

The PicoFlex high voltage floating picoammeter is composed of a particular transimpedance input stage for current sensing, combined with several analogue signal conditioning and filtering stages with state-of-the-art electronics. A high-speed fibre-optic interface combined with a high-voltage isolated DC/DC converter allow the input stage to be biased up to 6 kV with respect to the ground, allowing measurements to be made of ultra-low currents referred to an external high voltage power supply.
Samples may be acquired from the PicoFlex in digital form directly from the Ethernet interface, using either TCP/IP or UDP transmission protocols. A DAC output is provided for user convenience if an analogue signal is required for the type of measurement.

 

Applications

  • I-V characterisation on semiconductor and optoelectronic devices
  • Positive intrinsic negative (PIN) and avalanche photodiodes (APDs) testing
  • Measurement of photoemission current from high voltage floating samples
  • Measurement of MCP and Channeltrons currents irrespective of bias polarity
  • Measurement of polarized electrostatic lenses leakage currents

Deliverables
  • Pico FLEX, 2-channel, high-voltage floating picoammeter
  • Power supply unit
