let me share current technical parameters of electronics inside the spectrometer.
1. two computational units,
1.1. one based on Cyclone 5 has 132 SIMD cores running at 160MHz with one MADD per core, i.e. ca. 40GFlop/s real performance,
1.2. dual Intel Atom 500MHz with 6GFlop/s peak performance that achieve ca. 1GFlop/s (we do not need more), with 4GB/90MB/s NAND and 1GB RAM,
2. clock with 90fs jitter and 2ppb stability on well conditioned temperature range (don\'t forget about liquid cooling!!!),
3. dual 16bit ADC running at 160MHz with 40dB preamplifier, so, we can really see below 1mkV fluctuations on receiving coils.
4. two receiving and four transmitting coils as it is shown at the figure 5 at https://arxiv.org/abs/1706.00237
Finally the spectrometer cannot operate from standard USB, because it consumes ca 27Watt, so, we are modifying interconnect to 15V/3A + USB.
By plugging to USB, the spectrometer is recognized as USB disk with GUI software and free space for the spectra. You can connect the device to USB without external power supply to work with the setup and read collected spectra, but for the proper operation you need to power it with 15V/3A PSU.
