[Nicholas Murray]’s Composite Test Pattern Generator is a beautifully-made, palm-sized tool that uses an ESP32-based development board to output different test patterns in PAL/NTSC. If one is checking ...

In RF testing, an essential attribute of every RF signal generator is the maximum output power it can supply to a device under test (DUT) while maintaining spectral purity and level accuracy. The ...

As covered in my previous blog post, all diesel-powered generators should be loaded to at least 30% of their standby nameplate rating when exercised during their monthly test. If the connected load ...
