The new PicoSource AS108 Agile Synthesizer was recently unveiled at European Microwave Week 2018!
The AS108 is a USB-controlled vector (IQ) modulating signal synthesizer. It can generate sweeps, hops and lists in amplitude, frequency and phase, allowing it to emulate encoding schemes such as QPSK, QAM, ASK and FSK. It's supplied with ready-made software for Microsoft Windows, and also comes with a software development kit in case you wish to write your own program to control the device.
