It covers 500kHz to 62MHz, has a typical directivity of 42dB, a dynamic range of 74dB and a noise floor at 88dBm.

Features of its companion software include: Smith chart, impedance, SWR, reference coefficient and return loss plots; as well as open, short and load calibration modes; and measurement export and marker readouts.

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

“Our vector network analyser running on STEMlab is great solution that enables engineers to test and optimize the performance of antennas, RF filters, RF switches, couplers and cables” said Red Pitaya CEO Rok Mesar. “It is the perfect tool for professionals seeking affordable, highly functional test and measurement equipment, educators, students, makers, hobbyists and ham radio amateurs.”

In addition to the VNA module, to make measurements, users will need a STEMlab board.

STEMlabSTEMlab boards come with software that enables them to work as: oscilloscope, logic analyser, signal generator or spectrum analyser.

There are two basic forms of STEMlab, both with up to 125Msample/s over two analogue inputs (1Mohm 10pF) and two analogue outputs. ADCs and DACs on the 125-14 version are 14bit backed by 512Mbyte of RAM, and those on the 125-10 are 10bit with 256Mbyte. There is a spec overview here.

On-board processing is on a Xilinx Zynq 7010 FPGA which includes a dual-core ARM Cortex A9.

PC connection is via USB (which can accept a Wi-Fi dongle) and 1Gbit Ethernet.
