3.1.1.7. STEMlab 125-14 X-Channel System

The X-Channel STEMlab 125-14 system consists of multiple Low-Noise STEMlab 125-14 devices that are modified for clock and trigger synchronisation and also comes with SATA synchronisation cables and software that supports multi-channel RF signal acquisition and generation.

X-Channel STEMlab 125-14 system consists of:

  • one PRIMARY Low-Noise STEMlab 125-14 device, a standard Low-Noise STEMlab 125-14 device that provides clock and trigger signals to other SECONDARY Low-Noise STEMlab 125-14 devices.

  • one or multiple SECONDARY Low-Noise STEMlab 125-14 devices, that are modified in a way that they can receive clock and trigger signals from a PRIMARY device and distribute them to the next SECONDARY device. These are marked with an “S” sticker.

For detailed hardware specifications for Low-Noise STEMlab 125-14 devices used in the STEMlab 125-14 X-Channel System, please refer to the STEMlab 125-14 standard specs.

For more information about the software, please refer to: X-Channel streaming.
