Read-Write Analyzers

Guzik Read/Write Analyzers (RWA) work in conjunction with our Spinstands to write data to the disk media and read back the signal for detailed analysis. We have 3 RWA series available for DTR and non-DTR technologies. The RWA 4000, RWA DTR 3000 and RWA 2000 series offer upto 8Gbit/sec maximum write data rate and 3.2 GHz analog bandwidth for all parametric measurements. Each RWA features a pattern generator with 1psec resolution of bit pre-compensation and supports PRML chip integration. Servo writing and processing is provided for Guzik Spinstand models. Select the desired pre-amplifier (UP11, UP10 or UP8) as well as a variety of enhancements including programmable filters and PRML chip adapters.

Read-Write Analyzer Systems 4000 Series

Read-Write Analyzer Systems 4000 Series

The 4000 Series RWA System belongs to a new generation of Guzik test systems. Read-back signal from HGA is sampled using the high-speed A/D Converter of GSA 6000 unit with sampling rate up to 20 GSPS and ultra-deep memory up to 64GBytes. This approach allows for a direct measurement of perpendicular magnetic recording (PMR) signal, as opposed to indirect methods based on analog peak detector approach. No analog differentiator is required. The A/D converter chipset is provided by a major oscilloscope manufacturer; therefore you can expect the same digitized signal quality as you would from high-end oscilloscopes.
