DAQ for long duration mixed signal datalogging

[SMRTOKS]

Hi, i would like to log mixed signal data continuously for up to an hour on 2-16 channels. Frequency is 1-60MHz.

Can anyone advise which DAQ or digitizer should i use?

What are the specs that i should like out for in the cards?

Can normal LabView software help capture those data or is Flexlogger needed?

Thank you.

To your question, Logging data at 60MHz doesn't seem to be a DAQ job rather a digitizer, what are you sampling? and why does it need to be so fast?

Hi, im sampling an embedded system used for door control in railway system and the main communication protocol used is CAN and I2C with CPU operating at 60MHz. I need to sample and capture all the communication and I/O signals during all possible operational scenarios such the door open/closed/emergency unlock etc. This would enable me to simulate the door control system in-house and detect any faults. So i need advise on what DAQ/digitizer hardware and software to use. Thanks for any useful tips.

Do you want to be able to capture the CAN and I2C as analog signals (voltages) or digital signals (levels)? are there going to be any analog signal in the system?

Do you plan to do a playback system to capture and replicate the signals to test? are you looking to do a Hardware-In-Loop or Software-In-Loop testing?

Yes, i need to capture CAN, I2C and analog signals. I prefer hardware looping. i tried is on my e6378 (DAQ) and e6537 (DIO) but they could not reproduce all the signals and at the desired frequency. I tried all the settings in MAX but didnt work. So it would be great if someone can advise which card with what features can do the trick and what setting in MAX and any special algorithm to use. Thanks.
