Leveraging the crosspoint switching characteristics and best-in-class low-frequency noise performance of the ADC EV10AQ190 to implement software-defined instrumentation Moku:Pro

Moku:Pro is a scalable, high-performance test solution for developing and verifying next-generation devices and systems. It implements a software-defined instrument with 4 input channels and 4 output channels, with high flexibility.

The high-speed, high-precision data converter EV10AQ190 from Teledyne e2v is the best choice for this platform, providing Moku:Pro with first-class data acquisition performance. Its unique crosspoint switch enables the system to dynamically switch the channel usage mode and provide high-speed interleaved data; its excellent low-frequency noise characteristics help Moku:Pro achieve industry-leading noise performance using advanced ADC technology.

MOKU:PRO: A Software-Defined Instrumentation Platform for the Most Demanding Research and Engineering Applications

Moku:Pro achieves outstanding performance and flexibility through a sophisticated FPGA-based architecture, a high-bandwidth, low-noise analog front end, and powerful networking and storage. You get all the instruments you need quickly without sacrificing performance for flexibility. The innovative hybrid front-end design enables frequency-dependent signal mixing of multiple ADCs, providing excellent noise performance from audio to RF. It uses a single hardware platform to implement more than 10 different instruments, allowing engineers and researchers to simplify their test benches and even bring the lab home.

Moku:Pro enables engineering teams to work from home by integrating essential test equipment such as oscilloscopes and waveform generators into a single hardware platform. With its small size, power consumption as low as 115W and a suite of core test instruments included, remote work has never been easier. Moku:Pro's multi-instrument mode allows you to run multiple instruments simultaneously and connect them to each other to build a customized test system. Advanced users can access Moku:Pro's FPGA to implement custom digital signal processing by writing their own VHDL code. This cloud-based tool can be accessed directly from your browser, allowing you to develop, compile and implement custom algorithms in Moku:Pro without downloading software.

EV10AQ190: High-speed ADC for cutting-edge data acquisition on the MOKU:PRO platform

The EV10AQ190 is a 10-bit high-speed ADC from Teledyne e2v with 3.2GHz input analog bandwidth for high-speed, high-performance data acquisition. It contains internal crosspoint switches and a multi-core architecture that can be dynamically configured as a four-channel device up to 1.25Gsps, a dual-channel device up to 2.5Gsps, or a single-channel device up to 5Gsps. Moku:Pro takes advantage of this feature to enable its multi-instrument capability to switch between different ADC channel configurations.

Industry-leading noise performance is achieved by combining this 10-bit high-speed ADC with a lower-speed ADC using Liquid Instruments’ Hybrid ADC technology. This hybrid ADC technology is made possible in part by the EV10AQ190’s top-notch low-frequency noise performance (1/f noise). Here the 1/f performance of the high-speed EV10AQ190 and the performance improvement using Liquid Instruments’ Hybrid ADC technology are shown.

Building on the success of the EV10AQ190, Teledyne e2v recently released the successor 12-bit product EV12AQ605, which further breaks through the limitations of data acquisition in terms of resolution, sampling speed and performance.

The design of the crosspoint switch is continued to ensure the flexibility of channel usage for large data acquisition applications. In addition, it also improves the ease of use of the ADC through features such as serial interface and simpler synchronization mechanism.
