Picoscope 6404C limited to 1,25 GS/s for 2 channels?

Post by Picoscope0815 » Wed Jan 18, 2017 9:40 am

Hi all,

according to the data sheet the Picoscope 6404C has a maximum sampling rate of 5 GS/s for 1 channel and 2.5 GS/s for 2 channels usage.
Using the SDK with a modified Picoscope6000ExampleBlock program (Labview) I obtain an error 'invalid timebase' when only channel A and B is activated and the timebase is set to 1 (=0.4ns resolution =2.5 GS/s). It works fine for timebases >=2 or for 1 channel with any timebase.
How can that be?
Thanks for your help!

You need to select (A or B) and (C or D) for the 2 channels to get 2.5GS/s

Ah thanks! I misread that in the data sheet.
