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 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 →
I have have had for many years Mastech MS6811 cable tester. This tester model seems to be still selling typically at 15-30 Euros price range (and sometimes at higher price). Besides Mastech brands it is sold with different brand names for example AXIOMET and Sinometer. The MS6811 is designed to detect the most common wiring →
NOYAFA NF-8209 Network Cable Tester is used to measure cable continuity. It enables the measurement of connection errors in UTP / STP twisted pairs. The device is manufactured by SHENZHEN NOYAFA TECHNOLOGY CO., LTD and sold with several different brand names. NF-8209 Main features： 1. Two scan modes selectable: AC filter & Non AC filter. →
I wanted to get a station that had both soldering iron and hot air solder integrated to one compact device. I found product JCD 8898 2 in 1 750W Soldering Station Hot Air Heater LCD Digital Display Soldering Iron Welding Rework Station for Cell-phone BGA SMD PCB IC Repair available at low price. Features: Hot →
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 →
I had one DIY laboratory power supply that has served me well for a long time, but there are testes where I need another laboratory power supply. Instead of building a traditional power supply with linear regulator and large heatsink, I went to another route: build one from switch mode power supply and adjustable switch →
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 →
A signal generator is an electronic device that generates repeating or non-repeating electronic signals in either the analog or the digital domain. These generated signals are used as a stimulus for electronic measurements. There are many different types of signal generators with different purposes and applications. For analogue signal generation I have used for very →
Years ago you had to either build your own signal generator or buy usually a quite expensive signal generator. Lately there has been a push for very cheap ($15-25) digital function generator kits available from China. I wrote about some interesting function generator devices few years ago, and here is a closer look to one →
