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

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

The console has 3 transmit channels and 4 receive channels with LNA and TR switches 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 on our proprietary 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.
