Pz5M Medically Isolated Neurodigitizer - TDT RZ2 Manual

PZ5M Medically Isolated
NeuroDigitizer
PZ5M Overview
The PZ5M is a multi-modal neurodigitizer, suitable for recording a broad range of
biological potentials, combining the functionality of high and low impedance amplifiers
in a single device. The device is battery operated with alternative Mains power, used
primarily for charging, with full biomedical isolation for subject safety. The rack-
mountable PZ5M-512 can be used for simultaneous input of EEG, EMG, LFP and
Single Unit signals. It is available with 256 channels (PZ5M-256) or 512 channels
(PZM-512).
By oversampling the signal with very fast instrumentation grade converters, TDT's
custom hybrid A/D circuit yields 28 bits of resolution and unparalleled dynamic
range. Optional DC coupling offers zero phase distortion across the signal bandwidth.
Sampling rate and down-sampling filters can be optimized on each logical amplifier,
ensuring the best possible signal fidelity for the intended input type. The +/-500 mV
input range is large enough to accept any biological potential and most stimulus
artifacts without saturating.
The neurodigitizer inputs are organized into multiple banks of 64 channels. Each
bank is electrically isolated, meaning the ground and reference channels are not
inherently shared between banks. Multiple banks can be grouped into a single logical
amplifier that shares the same settings and ground/reference across each bank in the
logical amplifier. There are several different referencing modes, optimizing ground and
reference for different types of recording. Each logical amplifier can use the ground
as a reference, use a shared reference, use a unique reference on each bank or
implement full per-channel differential referencing.
A touchscreen interface provides immediate preview of inputs, impedance checking
and real-time control and configuration options for each amplifier bank.
