scan rate

[ASIM_BHATTI]

Hello everyone

I read  PCI 6255 data sheet and it tells me that maximum sampling rate is 1.25 M samples/s and scan rate is 750 Ksamples/s.

Now if i read all 80 channels(single ended), what will be the sampling rate of each individual channel? i.e (1.25 Msamples/s)/80 or (750 Ksamples/s)/80?

and second is if instead 0f 80 single ended inputs, if i use 40 differential inputs what  will be individual channel sample rate?

I f you have just one channel to read you can have 1.25 MS/s.

If you have n channels to acquire, you have a maximal frequency of 750 kS/s/ n.

It's the same for single or differential channels.

Hello Asim,

Just a thought

Try sticking to a single post for your queries.

It would not only make followup easier but also would serve as a 'one stop read' for any soultion seekers in future

Read Jaimie's post here for further information on your query
