RadioProcessor Model G

Complete RF Acquisition and Excitation System with Digital Detection, Real-Time Signal Processing, and Three Gradient Voltage Outputs


RadioProcessor Model G is an enhanced version of the versatile RadioProcessor design.  It greatly expands upon the already extensive capabilities of the RadioProcessor with the addition of three gradient voltage outputs.  This state-of-the-art design can serve as a complete system-on-chip solution for Magnetic Resonance Imaging (MRI), Nuclear Magnetic Resonance (NMR) and Nuclear Quadrupole Resonance (NQR) with spectrometer frequencies from 0 to 100 MHz (certain restrictions apply, see the Manual).

This unique digital system is housed on a small form factor PCI board, providing users with a compelling price/size/performance proposition unmatched by any other device on the market today.

Key Specifications:

  • Three controllable gradient voltage outputs.
  • Integrates excitation and acquisition components onto a single PCI card.
  • Directly captures and digitally demodulates IF/RF signals. The desired baseband bandwidth is user definable through software.
  • Generates completely formed RF excitation pulses as well as high resolution digital control signals.
  • Arbitrary Waveform Generation (AWG or 'shaped pulse') capability.
  • Maintains signal coherence between excitation and acquisition systems at all frequencies.
  • Samples the input signal at up to 75 Ms/s with 14-bit resolution.
  • Captures input signals above the Nyquist frequency, up to approximately 100 MHz.
  • With signal detection enabled, provides up to 10 MHz bandwidth of baseband data.
  • Direct Digital Synthesis generates RF output pulses with 14-bit resolution up to 300 Ms/s clock frequency.
  • Pulse setting resolution up to 13.3 ns, pulses from 66.6 ns to days per interval.
  • Zero-latency phase and frequency switching.
  • Wide-bandwidth input amplifier and A/D converter allow for undersampling applications.


Advanced, autonomous, broadband, Nuclear Magnetic Resonance (NMR), Magnetic Resonance Imaging (MRI), and Nuclear Quadrupole Resonance (NQR) experiments from 0 to 100 MHz
