XDAQ Acquisition Systems
Acquisition systems recording at 30 kHz and 16 bits in record or record-plus-stimulate mode, engineered and manufactured by Kontex and commercialized by NeuroNexus.
What all three share
30 kHz sampling, 16-bit resolution, Thunderbolt 3+ to the computer, with USB3 and Ethernet also available. Headstages connect over micro-HDMI. All three run in record and record-plus-stimulate modes, and all three synchronize their inputs on one clock rather than aligning streams afterwards.
Where they differ
| record channels | throughput units | power | video | opto channels | mass | |
|---|---|---|---|---|---|---|
| ALL-IN-ONE | 1,024 | 16 | DC | yes | 4 | 3.05 kg |
| ONE+ | 512 | 16 | DC | no | 0 | 2.81 kg |
| CORE2 | 512 | 8 | USB-C | no | 0 | 900 g |
Channel count is what you buy. The decision is usually something else: whether the rig travels. CORE2 runs off USB-C at 900 g, so it goes to a shared scope, a surgical suite or another building without a power search. ALL-IN-ONE does not move, and in exchange carries the whole experiment — 1,024 channels, synchronized video, and four optogenetic channels on the same clock as the neural data. ONE+ sits between them: full throughput units and mains power, without the video and opto.
Throughput units and channels are different numbers
Throughput units govern how many headstage ports can stream at once; record channels govern how much is captured. CORE2 has half the throughput units of ONE+ at the same 512 channels, so the two differ in how many headstages can run simultaneously, not in total capacity.
GPIO
ALL-IN-ONE and ONE+ carry 8 analog in, 8 analog out and 32 digital I/O; CORE2 carries 7, 7 and 31.
