PLUGSYS Monophasic Action Potential Module (MAPM)
Use for capturing and amplifying monophasic action potentials (MAPs)
The Monophasic Action Potential Module (MAP) is for capturing and amplifying monophasic action potentials (MAPs) in the PLUGSYS system. It has to be connected to special MAP electrodes. This module incorporates isolated input amplifiers in order to avoid hum interference. In this way the inputs are isolated electrically from the output circuits and from the housing.
The output voltages of the amplified MAP signals can be switched with jumpers to the PLUGSYS system bus. From the system bus they can be picked off by a Recorder Output Module (ROM) for direct recording or a DAQ Hardware PLUGSYS for data acquisition by computer. A square-wave calibration generator with a 10 mV amplitude is incorporated for calibrating the amplitudes.
Inputs: A special connection box is required for connecting the MAP electrodes, with separate switch-off facility for the individual channels. The connection box has to be placed close to the electrodes so that the unscreened electrode leads can be kept as short as possible. The box is not part of the module and has to be ordered separately.
