I am considering the purchase of a Picoscope 4424 and need some information about the time delay between measurements on 2 or 4 channels : How simultaneous is the sampling on the different channels (for instance at 200KSa/s sampling rate) ?
They will be out by half a sample period on the highest sampling rate when using 4 channels. The highest sampling rate is 20 MS/s when using 4 channels, this makes the period 50 ns. The samples on channel B and D will be out 25 ns compared to channel A and C. This is true even for the lower sampling rates, at 200 kS/s there will still only be 25 ns difference.

Hi, I would like to verify how this is true for Picoscope 3206D - do I expect right that there a defined fixed delay between the channels (1 ns in this case), and the same holds for 5200 series (in 8-bit mode)?
I want to compare channel A with channels B and C which should be simultaneous in phase else I am unable to prove what I set out to do. Is a 2408B four channel device able to show simulataneousness (if thats a word) of these channels. Rob
