The Challenge:

Nuclear Magnetic Resonance (NMR) Spectroscopy is a technique used for determining the structure of organic compounds. For scientists to be able to measure the exact structure of compounds to understand their properties is key.

If you apply some resonant RF energy it will cause the nuclei to jump to a higher-energy state and the nuclei magnetic moments will rotate or process. Traditionally an LO, mixer (upconverter) and arbitrary waveform generator would be used to generate the appropriate resonant RF pulse. A sensitive RF receiver or lock-in amplifier would be used to measure the emitted energy as the energy levels decay.

Not only is this setup is complex, takes up a lot of rack space and costly, but it hold the risk of errors in the test output because as a result of multi part setup and large number of connectors between devices.

The Solution:

With a product such as the Tabor Proteus a direct to RF or Microwave pulse can be generated, and the wideband digitizer option of the arbitrary waveform transceiver can be used as the receiver.

Proteus also has a tightly coupled Generation and Analysis Architecture. Utilizing PCI express Gen 3x8 lanes connection, it enables up to 64Gb/s of data transfer speed ,real time data streaming directly to the FPGA for continuous and infinite waveform generation, and a high speed control system providing a feedback loop.

The Outcome:

  • High speed interfaces sped up the measurement setup
  • Deep memory facilitated higher T2 measurement times
  • Compact modular form factor created a significant reduction in space of required equipment.
