Advantest Corp. has announced its T2000 8GWGD instrument that features an 8Gsps waveform generator and an 8GHz digitizer into a module for testing SoC devices used in mass-storage devices, such as hard disc drives (HDDs). Configured with the 8GWGD and 8GDM (8Gbit/s digital module), the device can handle fast SerDes PHY-layer interfaces and complex, high-speed analogue waveform challenges typically found in mass-storage SoCs, stated the company.

Using an arbitrary wave generator (AWG), Advantest's module can source complex signals such as partial response maximum likelihood (PRML) waveforms and multi-tone waveforms with a wide range of frequencies for high-speed ADCs and analogue front-end devices including preamplifiers. A unique feature is the gate output, which can be synchronised with the AWG to achieve high-precision timing.

The module's signal-capture digitizer is capable of enhancing system throughput and performing high-bandwidth analogue measurements. Moreover, it provides test solutions for eye-diagram, rise/fall time and time propagation delay measurements as well as cycle-to-cycle and long-time jitter. This enables testing of high-speed DACs and preamplifiers as well as fast digital-interface and phase-locked loop (PLL) devices.
