Slovenian startup disrupts market with bare bone instruments
When Ljubljana-based startup Red Pitaya launched what it describes as a Swiss army knife for engineers on crowd-funding site Kickstarter in 2013, it only took a few days to reach its initial USD 50,000 goal, ending up the campaign with over $256,000 pledged from 826 backers. Since then, over 30,000 Red Pitaya STEMlab units have been shipped worldwide, growing with them a fan base of developers willing to exchange and contribute open-source code for the FPGA-based instrument.

In essence, the Red Pitaya STEMlab is an ultra-portable highly configurable data acquisition module which researchers or industry can let run in the field or embed into machinery. Red Pitaya also offers to customize its board for volume orders that require specific arrangements. While all the code is open-source, with plenty of available resources contributed from a community of users, the STEMlab platform is proprietary and it is something that could be licensed to OEMs wanting to embed it in specific applications.

Now the piggy-back VNA running on STEMlab is about the same size of the original STEMlab. It covers a frequency range of 500 kHz to 62 MHz, has a directivity of 42 dB (typical), a dynamic range of 74 dB and a noise floor of 88 dBm. Software features include: plot formats (Smith chart, impedance, SWR, reference coefficient, return loss); open, short and load calibration modes; measurement export and marker readouts.

Included in the VNA module box are an RF SWR bridge module in an aluminium enclosure, calibration accessories (50 ohm, open & short load) and cables.
