Analog ECG Signal Generator

The Analog ECG Signal Generator utilizes analog output channels from National Instruments hardware, such as NI ELVIS II or NI data acquisition (DAQ) hardware, to generate a synthetic ECG signal.

Complete the following steps to generate an ECG signal from an ECG data file.

1. Launch the Analog ECG Signal Generator. If NI ELVIS II or NI DAQ hardware with analog output(s) is detected, the device name appears in the Device pull-down menu in the Instrument Control section.
2. Select a device from the Device pull-down menu.
3. Select the output channel in the Output Channel control. The output channel specifies the channel on the device to generate the synthetic ECG signal.
4. Switch the Source Selection control to From File to generate an ECG signal based on data measurements stored in an ECG data file.
5. Click the Settings ... button in the ECG from File section to display the Set Source File... configuration dialog box.
6. Click the Browse button and navigate to the file that contains the ECG parameters you want to use.
7. Place a checkmark in the Repeatly Generation? checkbox to enable the application to repeatedly use the ECG parameters in the file you specify to generate the ECG signal. If you do not place a checkmark in the Repeatedly Generation? checkbox, the application stops when the data in the file finishes generating an ECG signal.
8. Click the Close button to close the Set Source File... configuration dialog box.
9. Click the Run button to begin measuring signals.
10. Use the Gain knob control to select an appropriate amplitude of the output analog signal.
11. Click the Stop button to stop measuring the signal.
