In this episode Shahriar takes a close look at the Rohde & Schwarz FE170SR which is the world's first fully abstracted D-Band front-end module. Intended for early sub-terahertz 6G research, the fully integrated module is capable of seamlessly interfacing with both spectrum analyzers and oscilloscopes – only a 10MHz reference is needed!

The video goes over the history and evolution of external mixers and front-ends to better capture the uniqueness of the FE170SR. The internal block diagram and theory of operation of the instrument is also presented. Experiments show detailed measurement techniques using the FE170SR and the RTP oscilloscope. The integration of the FE170SR with R&S VSE is also presented through demodulation of broadband QAM signals at a carrier of 145GHz.

Furthermore, the newly released R&S Thermal Power Sensor at D-Band is also shown in the video:

In this episode Shahriar takes a look at a Torbal precision scale capable of resolving 0.001g! Unfortunately the unit shows an error of "Unload" when powered on. The teardown of the unit as well as the principle operation is described. The teardown also reveals the problem with the scale mechanism which is a broken link. The repair correct the problem and the scale shows excellent accuracy with calibrated weights. The live evaporation of Acetone is also shown using the precision balance.
