150612: measure rfi in dome from close lo cabinet

    We installed the anritsu mg3692c synthesizer in the lo racks in the dome on 12jun15. It was going to be used as the first LO.
The rfi from the anritsu was measured in the screen room (see above). We needed to know if the if/lo shielded cabinets gave enough isolation to not bother regular observations with the anritsu emissions.

To test this our setup was:
The results:
    the first image is a dynamic spectra of 480 seconds of data (.gif)
    The 2nd set of plots shows the spectral strength (.ps) (.pdf)
