GFT6304

The GFT6304 FMC module is the ideal digitizer for characterizing high speed signal. This compact digitizer can record four analog inputs at speed of 3.2 GS/s with 12 bits resolution.

The four flexible DC coupled analog front end contains a variable gain, variable bias control, over voltage protection and anti-aliasing filter. The settings are controlled with SPI interface via FMC+ connector.

The on-board clock is implemented with low phase noise clock and can be external via the FMC+ connector.

The GFT6304 is a standard FMC+ module according to VITA 57-1 2008 standard.

In option for lower cost channel number can be reduced to 2 channels and sample rate can be reduced to 2.7 GS/s.

Typical application: For stand-alone High Speed Digitizer application Greenfield Technology supply a carrier board (Ref: GFT6204) that provides:

  • External, channel and command trigger modes
  • 1 Mega samples par channel data memory
  • Lab software for quick and easy control of the digitizer.
