12-bit wideband digitizer, VSA software working together

As a demonstration of the new M9703A functionality, here is a live capture of how well the 12-bit wideband digitizer and the VSA software work together.

This short video shows the capture and demodulation of a GSM signal at 1.8 GHz.  Even though 1.8 GHz is way beyond the Nyquist frequency of the 1.6 GS/s digitizer, the digital down-conversion algorithm on the M9703A allows us to capture the folded spectrum of this signal at 1.4 GHz. What we then see in the video is the use of the 89600 VSA software not only to control the M9703A acquisition, but then to mirror the captured spectrum and then demodulate the GSM signal.
