The
EXT-10C has a differential input with high
input resistance to avoid 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 system
consists of a module for the EPMS-07
system and a small headstage.
The EXT-10C is designed to be used with
the DPA-2F amplifier/filter module from
npi which combines additional gain stages
with high- and lowpass filters. |
The
EXT 10-2F has a differential input with
high input resistance to avoid noise and
the incoming signal can be processed in
several ways, optionally including
elimination of 50 Hz or 60 Hz noise
respectively using a four pole notch
filter. The output voltage signal is
available either filtered with variable
gain or unfiltered with an amplification
factor of ten. The system consists of a
module for the EPMS-07 system and a small
headstage.
Two LEDs indicate whether the amplifier is
running out of its linear range and an
analog balance monitor makes the control
of offsets easy. |
The
EXT-08 was designed for performing low
noise recordings of small extracellular
signals in slices or in vivo preparations
using fine tipped glass or metal
microelectrodes. The system consists of a
module for the EPMS-07 system and a small
headstage.
