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 synchronization 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, which is a standard Low-Noise STEMlab 125-14 device that provides a main clock and trigger 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 from a PRIMARY device and distribute it 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 software please refer to: X-Channel streaming.
