The meter has automatic detection PNP and NPN type bipolar transistors , N, P -channel MOSFET, JFET FET , diodes , two diodes, thyristors , resistors , capacitors

Lutron LCR-9063

I bought a Lutron LCR-9063 meter long time ago (expect around 20 years or more) to be able to measure value of coils and capacitors. I has worked well for me. What looks like the same meter are sold as VOLTCRAFT LCR-9063 Component tester. This meter is designed for measuring resistance, inductance and capacitance. LCR-9063

tinySA RF spectrum analyzer

TinySA is an amazing gizmo! I have already posted some video link on TinySA and here is some mode material on it. RF testing is getting quite popular these days, with many devices featuring wireless capabilities. However, RF test devices are quite expensive, or at least have been, as on few recent years many affordable

NanoVNA RF Demo kit

Got RF test kit to play with NanoVNA from Banggood: RF Demo Kit NanoVNA RF Tester Board Filter Attenuator for NanoVNA-F Vector Network Anaylzer. I selected this RF Demo Kit NanoVNA over another quite similar RF demo kit because this kit was cheaper and looked better. This RF Demo Kit is specially designed for RF

USB isolator

The USB isolator is a device that will pass USB signal from input to output connector, while providing galvanic isolation between them. USB isolators are used in applications where direct USB connection can create noise (ground loop noise to audio or measurement), direct connection can be unreliable (noise to USB signal) or where isolation is
