Wave Vision 5 Multiple Active Channel

Casey,
Yes, you can generally capture multiple channels at the same time. From the 'Signal Source' tab (top right corner), select the signal source to be from hardware and output both Channels A+B (via the drop-down selection box next to the HW button). Then capture data and use the 'Channels' Tab (top left) to configure the viewing options for the different channels.

Hi Josh:

Either I do not understand your response, or you misunderstood my question.  I do have two devices collecting data, but it is not simultaneous.  I would like to have channel 1 (Device A) and channel 2 (Device B) both active at the same time, however I can not get them to be.  For example if I am sampling a signal at 15 MHz through a splitter on both channels, starting with channel 1 as the active channel and then switch channel 2 to be active and turn off the signal generator, the spike remains on the plot for channel 1 and it is not actively sampling.  I have attached an FFT plot to illustrate my point.  I am also attaching an image of my options under signal source for your information.

Thanks,

Casey

Casey,

Perhaps I do not fully understand your setup. From your latest message, it appears that you are evaluating an ADC14155LFEB evaluation board. This has a single-channel ADC device, so I do not understand where the two separate channels are coming from. From my experience with the wavevision 5 data capture platform, your copmuter can only read from a single WaveVision 5 capture board at a time, and that board may usually read all the channels from a eval board it is connected to, simultaneously. But, I only see that your WV5 board is connected to an EVM with a single channel. Do I understand this correctly?

THanks, Josh

Hi Josh:

Actually, I am using two WV5 boards and two ADC14155LFEB evaluation boards.  I am sending a block diagram of my configuration.  I hope that clarifies, but please let me know if anything else about my setup is unclear.  

Thank you,

Casey

Casey,

To my knowledge, the WaveVIsion 5 software can only interact with one WaveVision 5 capture board at a time, so I do not believe that it is possible to capture from both boards simultaneously.

Hi Josh:

So there is no way to capture data from two ADC Eval Boards simultaneously?

Thanks,
Casey

Casey,
No, not with a WaveVision5 data capture board.

Hi Josh:

Are you aware of any other way to acquire data from two of the eval boards simultaneously/

Thanks,
Casey

Casey,
I am not aware of a way to do that. I think the best strategy is to use an EVM with a dual-channel device.
