Read out data from the Adinstruments Powerlab 8sp channel recorder usb port?

[Peter Gamma]

I bought an Adinstruments Powerlab /410 channel recorder. Unfortunately, there was no software included. The Adinstruments support offert me a replacement Chart software which is incuded to this recorder.

The Powerlab /410 needs a SCSI card, and the Adinstruments chart sofware is a post processing software. There is no real time analysis possible.

Later on, I bought an ADInstruments PowerLab 8SP recorder with an usb port. There was also no software incuded from the seller. The Adinstruments support told me, I could use the same Chart software for my second Adinstruments channel recorder.

The Adinstruments Labchart software offered by Adinstruments has real time analysis, but is too expensive for my purpose.

Is there an easy way to read out sensor data from an ADInstruments PowerLab 8SP usb port, to use it with 3 th party software?

I asked myself, can Scott Hardens Sound Card ECG device:

be used instead of an Adinstruments channel recorder? Both have 16 bit analog to digital conversion. There are lots of differences, but are the basics not identical?


I recently bought an Adinstruments 8SP for 200 USD on ebay. But for ECG it needs an additional Bioamp, which costs additional 150 USD on ebay. Is the Bioamp equivalent to the ECG breakout board of Scotts circuit, and the channel recorder equivalent to the rest of Scotts circuit?

I asked the Adinstruments support how many EEG channels the Adinstruments 8SP supports, and whether they are validated data available for EEG recordings? No, no validated data available.

The 8 SP works for 8 EEG channels, and I would need to buy another Biamp, the Octal, which looks very expensive, I did not ask for the price. Furthermore I would need to upgrade from Labchart 7 (which I don t have, I have the Adinstruments Chart software) to Labchat 8, since the newer Adinstruments amplifier need Labchart 8.

Therefore, EEG validation with an  old Adinstruments 8SP device seems not to be a project which make sense.  Unfortunately, there are very little validation data available for low-cost EEG devices. One of the rare exeptions is Alexandre Brachants EEG ranking:

Any ideas how to obtain an affordable EEG reference device which can be used to validate DIY EEG devices?
