Not too much efforts was made before this PXIe-5644R did signal generation and analysis, just connected 2 SATA power cables and 1 SFF-8643 cable carrying PCIe from Intel NUC PC. I've installed NI RFmx suite, plenty of resources to explore. This guy is really hot while working...

Introduced a 30 year-old HP 33120A function generator to my lab, IC date code shows it's manufactured in 1996, but still works nicely after some simple cleaning and maintenance.

Just out of curiosity and created a prototype of SCD30 CO2 sensor with arduino, this little sensor from Sensirion can measure CO2 ppm with a cool method of optical absorption, and also output temperature, relative humidity values at the same time.

Recent assembly of a UHF turnstile antenna referring to Alicja' design, measured SWR is ~1.8 from 430~440MHz.
