I just noticed that Digilent has released a version of their Waveforms software that includes a new Spectrum Analyzer instrument (10MHz BW).
www.digilentinc.com/Products/Detail.cfm?Prod=WAVEFORMSSome related info from the newest Analog Discovery brochure....
"Spectrum Analyzer New!
• Performs FFT or CZT algorithm on analog input channels and displays power spectrum
• Frequency range adjustments in center/span or start/stop modes
• Linear or logarithmic frequency scale
• Peak tracking option finds peak power and adjusts display to keep peak in center of display
• Vertical axis supports voltage-peak, voltage-RMS, dBV and dBu display options
• Windowing options include rectangular, triangular, hamming, Cosine, and many others
• Cursors and automatic measurements including noise floor, SFDR, SNR, THD and many others
• Data file import/export using standard formats"
Pretty nice little addition that will let me look at a chunk of the frequency spectrum that's below my RF Explorer-3G's 15MHz-2.7GHz bandwidth.
