SPECIFICATIONS
SIP 385
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:
SECTION DESCRIPTION
A
Differential Amplifier:
 |
Common
Mode Rejection Ratio (CMRR): 80 dB |
|
Gain:
120 dB |
B
Differential Amplifier with Sensitivity to 5 mV
|
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).
SIP385B-2P
Biomedical Instrumentation Panel
|
Pulse
Generator uses photoplethysmography |
|
Direct
Digital Readout of Pulse Rate |
|
Temperature
Control Circuits with digital display, accurate to 0.10° Centigrade
or Fahrenheit, switchable |
|
Galvanic
Skin Resistance (GSR) with signal test button and variable gain
control |
|
Signal
Amplifier and gain control |
|
VCO
controlled Light and Sound Bar for audiovisual effects |
|
GSR
Circuit responds to sweat radiation on the hand (special Electrodes
and cable are provided) |
ACCESSORIES
|
