Test and Measurement Forum

Hi Folks,
New to the board and have a quick question. I currently have a BioSig Instruments grab pulse bar which reads the electrical signals 'beats" from your heart. This company can customize the output to be read using an oscope (1 volt output or whatever is recommended). What I'm trying to accomplish is to get this electrical pulse up on a 32" TV monitor so the kids can see a visual representation of their current heart rate. It doesn't have to be medically accurate just something cool for them to look at which resembles an ECG kinda look. if I can get the signal into a computer I can then use the video out to the monitor. Also since this is a non-profit organization our budget is relatively small but we do have some money. I was looking at the 2200 Unit for example. Any thoughts would be greatly appreciated.

Hi our entry level 2203 should be more than sufficient to measure the signal.

Our software is free and since it is all windows based, it should be no problem having it on a big screen.

Kind regards

I am also developing an EKG exhibit and am considering the 2205, and need to know if the trace progresses across the screen constantly, or is the signal presented as a static trace. As this will be measuring heart signals, which vary in frequency and have multiple peaks and valleys per beat, so signal display in real time is critical.

The EKG device that I made for detecting the heart signal works quite well with our bench Oscilloscope, but the low price USB 'scope that I initially bought only captures a static view or the waveform that refreshes every few seconds, not very compelling.

Also, does the screen view of the Picoscope 6 expand to enlarge the waveform?

Thanks for the hepl,

Hi this depends on the timebase you select. So if for example you had 100ms/division, so 1 second across the screen the device would capture the data then transfer it to the PC and display the waveform, this is called block mode.

If on the other hand you chose 200ms/division or slower time bases , the device changes to streaming mode and it will operate in streaming mode. In this mode you will see the data being updated on the screen as it happens.

Hope this helps.

Thanks for the reply. I would be using the 200ms setting or slower, so this will meet my needs.

Does the display window expand to the limits of the screen? I have tried the demo software and it fills my 24" screen, so it's huge. Just want to make sure that this will be the case with the 2205 scope.

Thanks again,
GR

Hi yes,

The software is the same for all the scopes, the only difference will be in the hardware spec of the product.

Kind regards
