SIP385 Biomedical Instrumentation

The course contains two prewired panels with a variety of cables and accessories. It provides training in basic monitoring circuitry, such as ECG, EEG, EMG, pulse rate, GSR, and temperature monitors. Safety is stressed in the program, and live measurements can be made on students. The course provides for approximately 75-100 hours of instruction.

EQUIPMENT SPECIFICATIONS
SIP385B-1P Biomedical Instrumentation Panel
Consists of the following sections:

	Common Mode Rejection Ratio (CMRR): 80 dB
	Gain: 120 dB

	Frequency Response: DC to approximately 1 KHz
	Low-Pass and High -Pass Filters provide required frequency responses for ECG or EEG
	Input Safety Devices limit input voltage for protection against line power
	Control Switches for varying rolloff frequencies and amplifier gain

C Optocoupler isolates the front end amplifier and reference ground from earth ground circuitry

D Signal Processor provides gain for such signals as the R wave in an ECG signal

E 60 Cycle Notch Filter can be switched in or out of the circuit to provide 50/60 Hz trapping

F 8-14 Hz Amplifier is designed to provide bandpass for signals in the 8-14 Hz region

G Output Amplifier provides additional gain for recording various physiological signals

H Isolated Power Supplies to isolate the front end amplifier from the common earth ground
supply (provides an additional margin of safety)

I Polarity Correction Circuitry enables the R wave to be either positive or negative; the output
is always a positive signal

J Pulse Stretching Circuit uses the R wave as the signal and converts it into a rectangular pulse

K Tone Generator produces the tone whose on period is controlled by the Pulse Stretcher Circuit

SECTION DESCRIPTION

L Integrator Circuit

	Converts the pulse stretched signal into a DC level for the 1 mA meter
	Pulse Rate is read on a calibrated meter

The Panel operates from the Power Supply Base (S300PSB).
