16-Channel Micro Preamplifier μPA16
The micro preamplifier with 16 electrode inputs μPA16
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 μPA16 is equipped with an Omnetics
socket for NeuroNexus probes C16, C32, F16, and CM16.
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.
Input Connector Omnetics A79039-001

REF
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.
