Horizontal Headstage 128-Channel Datalogger (HH128)

The HH128 neural datalogger records 128 channels of full data rate broadband electrophysiology data for experiments with rats, marmosets or larger model species. It can be used to record in both tethered or untethered (wireless) experiments. When recording untethered, the HH128 amplifies, digitizes and records neural data to the onboard microSD card under battery power. In tethered mode, the HH128 streams data to the MCU via HDMI where it is recorded to the local computer and can be viewed in Trodes.
