pci-6014 comparison with pci-6221

[Blair_Hogg]

I currently have a system using the PCI-6014 B series card. Can I replace this with the PCI-6221 M series card and the appropriate cable (shc68-68-epm) for better performance?

The system uses the PCI-6014, sh68-68-ep cable and cb-68lp connector block.

It looks like the PCI-6221 and shc68-68-epm cable are a drop in replacement with better specs.

I am generating 300-3kHz sinusoidal waveforms and the 10ks/S output rate leaves the waveform excessively quantized. I may also need to superimpose a 50kHz signal over the audio band signal and would need to do that via an external generator and mixer without the higher output rate of the 6221.

Thanks,

Blair

Hello Blair,

As far as the upgrade to the PCI-6221, or any M Series card goes there is one thing to keep in mind.  I'm not sure which driver you're using with the PCI-6014 card, but it supports both Traditional NI-DAQ as well as NI-DAQmx.  If you're using NI-DAQmx any M Series card would be a drop in replacement as long as it had at least the same number or more of all the types of channels you need (i.e. 2 analog outputs, analog inputs, etc.).  If you're using Traditional NI-DAQ then you would need to upgrade your code to NI-DAQmx to use an M Series device.

That being said, depending on your application and needs there may be another card that could offer even better performance.  For instance, many of DAQ cards offer analog output update rates at 1MS/s and above--if you only need analog outputs you may want to consider an analog output card from the NI 67XX series (PCI-6711, PCI-6733).

Since there is such a wide range of products available it may be helpful for you to use this product search tool.  It will allow you to filter all of the DAQ cards National Instruments makes based on your particular needs.  Also, if you'd like to speak directly with a technical representative for product selection advice please feel free to contact National Instruments directly using the contact information at www.ni.com/contact.

I hope this helps, and have a great day!

Thanks, Brooks.

We grew this system out of a LV4 system that used AT style E series units, so all of the code uses traditional NI-Daq drivers. Looks like I have some code work to do before using M series units.
