Test and Measurement Forum

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) ?

If you are using one out of A and B and/or one out of C and D the samples should be simultaneously. On the two channel product they are always simultaneously sampled.

thanks.

Could you provide an answer for the 4 channel use case ?

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.
