System Description
The EXT-10C was designed for performing low noise recordings of small extracellular
signals in slices or in
in vivo
preparations using fine tipped glass or metal microelectrodes.
The system consists of a module for the npi EPMS-07 modular system and a small headstage
with a holding bar.
The EXT-10C has a differential input with high input resistance for minimizing noise and the
incoming signal can be compensated for offset and capacity of the microelectrode by the two
potentiometers OFFSET and C-COMP. An analog balance monitor makes the control of
offsets easy. The recorded signal can be obtained either AC with GAIN of 100, 1k or 10k or
DC with GAIN of 10, 100 or 1k. An optional NOTCH filter eliminates 50/60 Hz noise.
The EXT-10C is designed to be used with the DPA-2F preamplifier/filter module from npi
which combines additional gain stages with high- and lowpass filters.
