The EPC 10 USB amplifiers are available with one (EPC 10
USB), two (EPC 10 USB
Double), three (EPC 10 USB Triple) or four (EPC 10 USB
Quadro) amplifiers. This
hardware product line is fully integrated with HEKA's
data acquisition LIH 8+8
AD/DA interface. The interface utilizes USB 2.0 and high
speed processing
technologies. The advanced integration of the EPC 10 USB
with the interface and
software minimizes total recording noise, eliminates
compatibility problems and
reduces additional equipment expenses and set-up time.
The digital control of all amplifier functions has been
designed with two
advantages in mind. Firstly, as the computer controls the
functions of the amplifier,
the data acquisition program can access and store
variables that describe all of the
settings during an experiment. Secondly, computer control
allows the user to highly
automated the experiments.
These include automatic switching (e.g, switching between
the settings for
establishing a seal or those for single channel
recording) and also the automatic
adjustment of capacitance transients cancellation and
series resistance
compensation. In fact, digital control of every
adjustable parameter in the amplifier
circuitry is implemented, including the calibration
adjustments.
