Read-Write Analyzers

The 4000 TDMR Series RWA System belongs to a new generation of Guzik test systems. Up-to three Read-back signals from HGA are sampled using the high-speed A/D Converters of GSA 6000 unit with sampling rate of 20 GSa/s and ultra-deep memory up to 32 GBytes per channel. The A/D converter chipset is provided by a major oscilloscope manufacturer.

RWA 4006 TDMR Read-Write Analyzer is a part of the new generation all-digital Guzik 4000 Series test systems. RWA 4006 TDMR requires Guzik signal analyzer GSA 6044 to provide a complete RWA TDMR solution for magnetic recording test applications.

Guzik GSA 6000 series Signal Analyzer combines high-speed waveform digitizer with built-in digital signal processing hardware and high-speed data transfer link to a computer. The Signal Analyzer comes in a space-saving display-less 2U 19” rack-mounted form factor.

Base models are capable of 2Gbit/sec, 3Gbit/sec, and 4Gbit/sec Provide tests and measurements of both DTR and non-DTR components (heads and disk drive media) DTR 3000 Series can work with both Guzik and non-Guzik spinstands
