BI4NLB, test engineer, HAM interested in home-brew rigs and antennas, EME, active on all HF bands and in contest. I'm also AG5MN. I was BH4DQS from 2016~2018.
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...
Here comes the new toy~got an used PXIe-5644R from NI, plan to dock it with the backplane designed by Marsupilami and try some RF input and output soon~

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.
