Fluke MPS450 - Analog Printed Circuit Assembly; ECG Post Printed Circuit Assembly

MPS450 SERVICE MANUAL FUNCTIONAL DESCRIPTION
9
ANALOG PRINTED CIRCUIT ASSEMBLY
The Analog PCA is the location of all patient-simulation circuits, which are controlled by the
microcomputer on the Digital PCA:
o ECG-wave generation
o ECG-amplitude control
o Pacer-pulse amplitude and width control
o Respiration-lead and baseline-impedance selection
o Respiration-wave generation
o Respiration-amplitude control
o Blood-pressure-sensitivity selection
o Blood-pressure-wave generation
o Blood-pressure excitation-voltage modulation
o Temperature-resistance selection
o Cardiac-output-wave generation
o Auxiliary port operation
o Connectors:
Digital/Analog PCA connector
ECG PCA Assembly connector
Blood-pressure channels 1 – 4 connectors
ECG POST PRINTED CIRCUIT ASSEMBLY
The ECG Post PCA is the location of protection circuitry. It connects to the ECG signals from the
Analog PCA and routes the signals to the ten ECG posts.
