WDM5000 Series Waveform Digitizers – Obsolete

Waveform Digitizers

The Guzik WDM 5000 Waveform Digitizer family provides high-speed waveform capture and parametric analysis capabilities for disk drive head and media testing as well as high-speed transient waveform capture. Unlike conventional oscilloscopes or waveform digitizers, the WDM 5000’s architecture was built to provide ultra-long waveform memory and the highest measurement throughput for capturing and processing single shot data or testing on the factory floor.  The 12.5 GHz analog bandwidth combined with 40 GSa/s sampling rate and ultra long waveform capture memory provides the capability to capture the most demanding signals.

The WDM5000 Waveform Digitizers provide the world’s longest waveform capture time window.  At the maximum speed of 40 GSa/s and using all 4 Gpoints of storage, 100 msec of waveform data can be captured and stored for further analysis. In addition, the WDM 5000 Series utilizes a high-speed hardware-based Digital Data Processor with speeds up to 5 GSa/s (for parametric measurements). The product can execute customer-defined complex measurement algorithms, and it does it almost 100 times faster than digital oscilloscopes currently available on the market. The WDM 5000 architecture, built on the industry-standard Advanced TCA platform, allows customers to protect their system investment by allowing for future component upgrades.

The WDM 5000 Signal Explorer Control and Interface software is included as a standard accessory with each WDM 5000 Waveform Digitizer unit. This software allows stand-alone operation of the WDM 5000 digitizer with a host computer. (The host computer must have an open PCI Express x1 slot to house the Guzik PCIe x1 Bridge Card or an approved PCIe x1 Express Card, such as the One Stop Systems OSS-PCIe-HIB2-EC-x1 Express Card.) The WDM 5000 connects to the host computer via aPCIe x1 cable, and the Signal Explorer software provides a real time oscilloscope-like user interface.

Waveform data is updated in real-time, so the user experience is similar to using a modern PC-based oscilloscope. Channel Tabs will appear for each channel provided by the particular WDM 5000 model being used. Controls are arranged at the bottom of the screen in a familiar and easy to navigate panel, and waveform data appears above. In addition to channel data, the FFT of any channel can be displayed as well. Since FFT’s are being processed in hardware, the display update is extremely fast. Measurement cursors, waveform zoom, and a variety of other visual measurement tools are provided to make operation quick and easy.
