What is the Maximum BandWidth for a Multicarrier Signal that the AWG Can Generate?

For the RFSG, What is the Maximum BandWidth for a Multicarrier Signal that the AWG Can Generate?

Ahmed,

Since the RFSG uses an AWG for waveform generation, if you can build the multicarrier waveform in software, you're only limited by the generation bandwidth of your device. For a PXIe-5672, according to the specs, that's 20 MHz; for a PXIe-5673, the specs say it's (in most cases) 100 MHz.

Thank you, and What about the Streaming? can I Stream an Instantaneous 20Mhz or 100MHz for a Long Period of Time Without any Gaps Between Shots?

Thanks In Advance

Hi Ahmed,

I would like to start off by stating that streaming is going to be dependant on quite a few other factors.  These include the sampling rate that you are using to generate your waveform, bus speeds (PXI vs PXIe), computer architecture (computer bridges etc.), resolution, etc.  The short answer to your question is Yes.  Our cards are capable of streaming data that includes signals across the entire bandwidth (20 or 100MHz) for long periods of time.   The long answer is that you need to make considerations for all of the additional factors mentioned.  This includes making sure that you are not trying to use a sampling rate that exceeds the capabilities of your hard-drive, CPU speeds, application development enviroment (ADE) speed, bus speeds, PCI or PCIe bridges, motherboard, etc.  We have some really good information about streaming, including some benchmarks, that can be found on our website. There is also a good article with more information about RF streaming here.  I would highly recommend reading the above documents and taking a look at our website for more information.  Please let me know if you have any additional questions.
