Hello,

I am using TI's ADS1293 evaluation board, we bought it very recently.

I followed all the steps as given in the user manual. I am unable to figure out the output ( PQRST signals)

The output is looking like a noise waveform. Please let us what can we do, to be able to see signals in a better way.

Regards

Hello Sainath,
What's your configuration 3-lead or 5-lead?
What's the input? Are you using a ECG simulator?
Thanks,
Vishy

Hello Vishy Viswanathan,
I have exactly the same problem as Sainath, with the 3-lead configuration. In my case, I'm not using an ECG simulator and what I obtain looks like a noise signal, could it be because of my electrodes?

Best regards,
Andrea

Andrea,

The ADS1293 does not work with dry patches because the impedance is too high and that causes the signal to float around. Are you using dry patches or using ones with gel?

At the beginning it is good to use an ECG simulator or function generator. Please see this post
