Precision current to voltage amplifier, for use with TRAP detectors.

Hauptmerkmale der Produktfamilie

High precision current to voltage amplifier

These amplifiers include a microprocessor for remoted set up and control. They use thermally stable, precision resistors to provide highly accurate conversion of current to voltage.

Manual or remote control

They provide six gain ranges from 10 KΩ to 1 GΩ. These ranges can be selected manually or by remote control using the USB interface and our software. They can also be selected manually using the rotary switch.

Power supply options

  • SDX-1153 preamp is power over the USB 2.0 and requires +5V at 500 mA.
  • SDX-1226-1 and -2 require use of an external DC power supply.
