High-frequency observations of the pulsar PSR1133+16 have been obtained to investigate microstructure on a time scale of 14 microsec. Most observations were restricted to the first component of the double-pulse profile. The data for both components confirm the general features of the microstructure described by Hankins (1971; 1972; 1973). Autocorrelation functions of the strong pulses often exhibit the linear feature associated with microstructure, extending from near-zero lag to several hundred microseconds and followed by a broader feature associated with the subpulse width. Some pulses displayed quasi-periodic behavior within the pulse.
