Integrated High Voltage

  • Avoids the need for a separate HV suppy
  • Precise programmable control of voltage
  • Choice of polarity and range up to positive or negative 1000 V
  • Short circuit protection and independent output voltage monitoring

Fiber-Optic Communications

Measurement data is transmitted through state-of-the-art fiber-optic cables. The benefits are numerous compared to other forms of data transmission.

  • Fiber-optics are immune to electrical interference
  • Minimal attenuation of light through fibers
  • Fast messaging over enormous distances
  • Radiation hard fiber materials

EPICS Support

Integrate device data collection and configuration into an EPICS system, without writing a single line of code using IG2.

  • Runs on Windows 7/8/10 and Debian Linux
  • Change PV names with simple XML configuration
  • Connect to multiple Pyramid devices at once
  • Add custom scale factors and offsets on a PV basis
  • Never have to recompile
  • Professional Pyramid support for bugs and features
