Low-Cost, Credit-Card-Sized, T&M Instrument Adds VNA Capabilities


Red Pitaya has announced a Vector Network Analyser (VNA) module for its low-cost credit-card-sized ‘STEMlab’ test and measurement platform, that allows it to measure electrical performance of RF components. According to the company, the VNA running on STEMlab enables engineers to test and optimize the performance of antennas, RF filters, RF switches, couplers and cables. It is the perfect tool for professionals seeking affordable, highly functional T&M equipment, educators, students, makers, hobbyists and HAMRADIO amateurs.

Red Pitaya Adds Vector Network Analyser Capabilities to Low-Cost Credit-Card-Sized, Reconfigurable STEMlab Instrument

The company has launched a Vector Network Analyser (VNA) new bridge module and application that enables STEMLab to function an affordable vector network analyzer (VNA), a precision measuring tool that tests the electrical performance of high-frequency components in the radio frequency.


“STEMlab is a credit-card-sized, multi-function, open-source and reconfigurable instrument that is designed to be a low-cost alternative to many expensive measurement and control instruments. STEMlab can function as an Oscilloscope, Logic Analyser, Signal Generator, Spectrum Analyzer and much more. The company says STEMlab is not just a product, rather it is a test and measurement environment that includes a board, an application marketplace and a source code library.”

Users – which vary from small student teams all the way up to large multi-national corporations – have described STEMlab as ‘the Swiss Army PenKnife for engineers’. STEMlab is based on high-end FPGA technology, enabling software and hardware programming, coupled with very accurate high-end ADCs. Customizable at the FPGA and CPU levels, STEMlab can process real-world signals.
