Hardware tools for reducing noise in micro-recordings
lun. 22 octobre 2018 by Martin DeudonA complete list of all hardware used for reducing noise in micro-electrode recordings is avalaible here.
Spectrum Analyzer SPECTRAN-NF 1010E
The Spectran NF-1010E from Aaronia is a spectrum analyzer. It can measures both electric and magnetic fields in a frequency range of 10Hz to 10kHz. It is very useful for localizing the source of noise in a complex environment. The Spectran NF-1010E comes with a Software which allows further analyses.

Power-Plant/Multiprise BADA LB-6600
The BADA LB-6600 is a power plant (multiprise) with 8 sockets. It also filters the incoming current from the mains (secteur).
Bada manual : bada_lb_6600
The total number of devices plugged in the BADA power-plant should note require more power than
the BADA can deliver : 3300W
The BADA power plant must be powered in with a cable able to conduct a sufficient power.
Shielded power cables
The mains (secteur) are the main source of 50Hz noise in the micro-recordings. One simple but effective step to greatly reduce this noise is to use shielded power cables. Each electronic device should be powered with a shielded cable.
