32-Channel Micro Preamplifier μPA32
The micro preamplifier with 32 electrode inputs μPA32
is connected to the microelectrode probes for providing
the initial tenfold amplification stage. Signal integrity
is safeguarded and noise pick up is significantly reduced
by this preamplifier compared to the use of signal buffers
with gain 1. The μPA32 is equipped with an Omnetics socket
for NeuroNexus probes CM32, F32, HP32, and MRCM32.
When using two μPA32 you can connect the NeuroNexus
probes H64 and HC64. It has an additional common ground
and a reference electrode input. The reference electrode
is ideally identical to the recording electrodes and placed
into a comparable but inactive area or tissue.
Background or noise signals that are picked up by both
the reference electrode and the recording electrodes
are removed. The very high input impedance ensures
stable long-term recordings.
Output Connector 44-Pin HD D-Sub male connector (Harting TB 09 56 300 5615)
