Description of the Gecho

The system is a complete RF chain (Spectrometer (Cameleon4) + Amplifiers + Pre-amplifiers) associated with a power supply. Gecho is assembled in a single 3U box.

The Gecho is a versatile system where one can add parts on request, such as a shim card or a gradient card.

Cameleon4

  • Integrated Linux operating system on dual core ARM processor
  • Operating from 1MHz to 900MHz
  • Low noise digital receiver
  • Optical gradient output
  • Simultaneous multi-channel observation
  • Cameleon basic configuration: 3 transmitters (TX), 4 receivers (RX)

 

RF Amplifier

  • Either 200-650 MHz
  • Or 5-310 MHz
  • Other configuration on request

 

Preamplifier

  • Up to 3 channel
  • 0.5 db low noise
  • High speed active Tx/Rx switch
  • RF filter

 

Power supply

  • Either+12V/+15V/+30V
  • European and american standard

 

General Purpose Input/Output (GPIO)

  • 4 TTL
  • 1 input

 

The console has 3 transmit channels and 4 receive channels with LNA and TR switch for each one. It can be configured for simultaneous acquisition on the 4 receivers at different observation frequencies.

The adjustment and adaptation of the probes are integrated with a directional coupler on each transmission channel.

The system comes with an unlimited number of licenses for our own acquisition and processing software: SPINit (running Windows). If you wish to keep your acquisition software, we also give access to the Driver, allowing you to ensure a link between your software and ours.

For an overview of the software, you can download SPINit.
