Hall sensors offers several advantages over shunts and CT’s – accuracy, linearity ... [Daniel] wanted to power his current probe with a 5V input derived from the USB socket on his oscilloscope.

With high measurement speed and stability, the R&S ZNB3000 vector network analyzer (VNA) supports large-scale RF component production. Its PCB-based frontend minimizes thermal drift, enabling reliable ...

The RF signal is strong enough to consistently ... ThermoWorks put multiple sensors in the shaft of the probe. Those four components give you a more accurate reading for the internal temperature ...

But as Alex Whittimore shows in this workshop from the 2020 Hackaday Remoticon, you can do a lot of RF emissions debugging with simple and inexpensive tools. Professionally-made probes in several ...
