The FASR Subsystems Testbed (FST) is a frequency-agile three-element interferometer located at the Owens Valley Radio Observatory in California. A frequency band of 500 MHz can be dynamically selected within the 1-9 GHz frequency FST operating range. The signal from each antenna is sampled at 1 Gsps and written to disk. The full-resolution time-domain data are then correlated offline to produce amplitude and phase spectra on three interferometric baselines. The FST was used on 14 December 2006 to observe the GOES X1.5 soft X-ray flare in NOAA/USAF active region 10930 at S06W46. The FST observed the event between 1.0-1.5 GHz with a time resolution of 20 ms and a frequency resolution of approximately 1 MHz, time sharing between observations sensitive to right- and left-circularly polarized radiation. A variety of coherent radio bursts was observed, including a highly circularly polarized "Zebra” burst characterized by 7-10 regularly spaced bands of emission in the dynamic spectrum. With new constraints available on the source size and the relative source position as a function of frequency, the double-plasma resonance model is explored, wherein emission in a given band occurs at the upper hybrid frequency that is, in turn, harmonically related to the local electron cyclotron frequency.
