Vector Network Analysis for Everyone from Pico Technology

The prestigious Microwave Journal just published a nice piece on Pico's new Vector Network Analyzer.  

It states: " Pico Technology has applied its expertise in compact USB instrumentation, combined with its experience with high-performance sampling oscilloscopes and time domain reflectometry, to bring an outstanding value in a high-quality, low-cost vector network analyzer.

If you work with high-speed data, communications or computing, you often need to characterize high-frequency interfaces, devices, multi-path interconnect and antennas. Today’s engineers and systems integrators do not have time to become microwave specialists. They need a straightforward, accurate, fast, portable and low-cost measurement instrument, and ideally one that can support developing applications such as 5G, IoT, radar and tissue and materials imaging.
Pico also included in their free-of-charge PicoVNA 2 software two utilities to tackle gain compression (P1dB) and AM to PM. Both of these use a port power sweep at each test frequency. Both measures are extracted using second-order interpolation.
Calibration standards and interconnect for vector network analysis can dominate both performance and costs. Pico offers PC3.5 and SMA, male and female test ports via flexible and flex-formable, phase- and flatness-stable test leads. Four mating calibration standards, with traceable data, are assembled into convenient male and female SOLT housings. Like the test leads, the SMA and PC3.5 calibration standards all use robust, high-precision stainless steel connectors.
