Abstract :
A radio polarimeter at 200 mc of time-sharing type is described. This instrument observes a set of two circular and four linear components of polarization in 1/200 of a second, with 1/1200 of a second interval for each component, so that practically a simultaneous observation of rapidly varying phenomenon such as a solar burst is made possible. Some details on the electronic switching, the square-law detector, and the method of calibration and checking are discussed.
