Step 4. Adjust Gain, Offset, Resample parameters to change brightness, 
baseline and so on. 

- 

Gain : Adjust the overall signal amplitude 

- 

Offset : Adjust the overall signal brightness 

- 

Resample : Adjust speed. Can also use to test the same waveform with 
different BPM values.

HRS Raw Data Format 

 

HRS supports Text file (*.txt) only, the detail format is as below:

：

 

Line 

Item 

Description 

1 

Sample Rate (Hz) 

The frequency of sampling per unit 
time.  

2 

Number of Samples 

The file has how many number of 
samples (N) 

3 

Sample Date 1 

The first sample data in the file 

4 

Sample Data 2 

The seconds sample data in the file 

…

 

…

 

…

 

N 

Sample Data(N-2) 

The (N-2) sample data in the file 

 

Note. The maximum number of samples and playback time depend on the memory space of 
computer. If HRS software can obtain more memory space from computer, the playback time 
can be longer. In normal situation, the playback time is around 2 hours.
