• Differentiator Module for recording signals such as dLVP/dt, dF/dt on an analogue recording device • Includes maximum and minimum tracking The HSE-HA Differentiator is a universal analog calculator for evaluating the rate of rise and fall of signals such as blood pressure dP/dt, force dF/dt, displacement, Intracellular Action Potential etc. The input signal is provided either from a PLUGSYS Preamplifier Module (e.g.TAM-A or TAM-D, having a Blood Pressure or a force Transducer) connected via the PLUGSYS bus system or from a PLUGSYS external preamplifier over the external input on the front panel. Output signals available are the differentiated signal and a tracking signal of its maximas and minimas. All the output signals are available via the PLUGSYS bus for further processing or for linking to a Chart Recorder using a Recording Output Module. The differentiated signal is also available at the auxiliary output on the front panel.
