Digital data bus capture using Agilent MSO6104A

[jerryguo]

Hi All,

I'm using LabView 8.6 to control Agilent MSO6104A scope for data acquisition. I have no problem with very basic digital and analog signal waveform acquisition but I can't figure out how to capture digital data bus (the scope can capture up to 16 channels of digital signals). Has anybody used the scope for that purpose before? I'd really appreciate if some one can point a direction for me. Thanks in advance!

Hi Jerry,

Have you seen the instrument driver for this device?  If you aren't using this already, it may help take some of the complexity out of the advanced operations.

Hi Michael,

Yes I found a driver from NI website and I have been using that driver for digital signal acquisition. It appears to me that the maximum number of points I can save using that driver is 2000 (there is a function to configure the acquisition record). I don't want to use anything like for loop for extended data acquisition because I'm performing high speed data acquisition (10Mbits/s) and I don't think LabView can execute the for loop at that speed. If anyone has ever implemented vi for high speed digital data acquisition can I get some example code? Thanks in advance.
