Spectrum GmbH M4x.22xx series modular PXIe-based digitisers

The Spectrum GmbH M4x.22xx series modular PXIe-based digitisers offer one, two or four fully synchronous channels.

Each channel is equipped with its own analog-to-digital converter (ADC), with real-time signal sampling at rates from 1.25 GS/s to 5 GS/s, and scope-like signal conditioning circuitry that allows programming of parameters such as input gain, signal offset and coupling.

The digitisers also offer bandwidth up to 1.5 GHz, making them suitable for automated testing applications where wideband electronic signals from DC to the GHz range need to be acquired and analysed.

Typical applications include semiconductor and component testing, radar, wireless and digital communications, laser and optical systems, automotive, power, physics, surveillance, medical science, aerospace and defence.

The flexible front-end circuitry of the product is complemented by a trigger system, an onboard acquisition memory of 4 GSamples and a host of data acquisition and readout modes. The combination makes it simple for the cards to capture even the most complex signals as well as work effortlessly with other modules in a test system.

Acquisition and readout modes include single-shot capture (for transient recording), FIFO (for streaming data directly over the bus), segmented memory (multiple recording), gated acquisition (gated sampling) or the combination of segmented acquisition of fast signals in parallel with slow continuous data recording (ABA mode). Trigger events can also be time stamped.
