This note reports on a solar application of an improved acoustooptical radio spectrograph in which a self-scanned array of photodiodes and an on-line computer produce calibrated spectra in real time. The operations of the solar spectrograph, the on-line minicomputer, the teletype interface, and the video display are described. Software corrections and other useful features and options are discussed. The formats of the acoustooptical radio spectrograph and the Culgoora scanning radio spectrograph are compared using several examples of dynamic spectra of solar radio bursts. These include a completely unpolarized type II burst, some type I storm bursts showing both right and left circular polarization, and several fast fiber-type drifting bursts. A comparison is also made with the Dwingeloo multichannel radio spectrograph, and it is noted that the acoustooptical spectrograph is limited by the noise contribution of the photodiode array, which is 30 to 33 dB below saturation at best.
