ECG Testing

The MPS450 sends a number of ECG waveforms to test and verify an ECG machine and
monitor. Performance waveforms can be used to test frequency response (both high and
low), sensitivity, gain drift, internal calibration, stylus damping, paper speed, linearity,
sweep speed, and more.
For square, pulse, sine, triangle, and R waves, both rate and amplitude are adjustable to a
wide range of preconfigured settings. R-wave width is also adjustable.
While running any performance waveform, outputs for respiration and blood pressure are
disabled; they are reactivated when a physiological waveform—such as normal sinus
rhythm—is selected.

Running a Performance Wave

The MPS450 offers a selection of preconfigured-rate settings for square, pulse, sine, and
triangle waves:
Square waveforms—available at 2 or 0.125 Hz—are used most frequently to test linearity,
amplitude, and frequency response.
Pulse waveforms—available at 30 or 60 BPM with a 60 ms pulse width—are especially useful
in measuring and calibrating paper speed, internal calibration signal (as compared with the
MPS450 calibration), sweep speed, stylus damping, sensitivity, gain and drift.
Sine waveforms—available at 0.5, 5, 10, 40, 50, 60, or 100 Hz—are used for a variety of tests,
including ECG sensitivity, frequency response (high and low), and accuracy.
Triangle waveforms—available at 2 or 2.5 Hz—are an important tool for testing the linearity
of an ECG unit.
