Profile: Guzik Technical Enterprises specializes in test and measurement equipment. Our product line includes digitizers, spinstands, R/W analyzers, amplifiers and other accessories. Our Guzik DTR 3000 spinstand includes a media centering system. When a disc with pre-printed servo information is mounted on a spinstand, the servo and data tracks can have eccentricity up to 50-100 micro-meters in the spin axis. The media centering system mechanically aligns the disk to reduce track eccentricity below 800 nm. The process is completely automated and typically takes less than 30 seconds. The Guzik DTR 3000 spinstand can be used in non-servo mode and embedded servo mode. The head suspension and some spinstand parts expand when the temperature changes during measurements. The embedded servo eliminates the positioning errors caused by this thermal expansion. The spinstand in the servo mode also suppresses low-frequency vibrations transmitted from the floor. Our Guzik WDM 5000 series waveform digitizers provide up to 13 GHz waveform capture bandwidth, and 40 GS/sec sampling rate in a display-less rackmounted format. In addition to the industry-leading acquisition system at the core of the WDM5000 family, the products feature up to 4 Gpoint waveform memory combined with customizable hardware parametric processing.
