Velleman K7000 signal tracer / injector

This signal tracer/injector has been designed to inject or detect a specific signal into an audio circuit in need of repair (such as amplifiers, radios, tone controls, …) so as to detect the fault. Signal tracer/injector is typically used when testing audio frequency circuits (there are also tracer/injector circuits for other applications as well). With

MT87 clamp meter

MT87 Digital Clamp Meter is the cheapest digital clamp multimeter I have found. It has been sold at price for less than 10 Euros/Dollars, while some other places sell the same mater often at around 20-30 Euros price. Main Features: ● Mini and compact design, easy to hold ● Data hold and LCD display, easy

Adjustable RF attenuator

RF attenuators are essentially electrical resistor circuits that are put in line with an RF signal and reduce the signal strength. The amount of resistances used is what determines the amount of attenuation. Basic circuits used in attenuators are pi pads (π-type) and T pads. The lost power in the attenuator is converted into heat.

Resistor decade box

Needed adjustable resistor for electronics lab. I found 0-9999 Ohm Simple Resistance Box Precision Variable Decade Resistor Teaching Instrument Measurement & Analysis Instruments from Tools on banggood for sale one day on the app. Specifications: 100% brand new and high quality Attenuation Range / Mini Step: 0 to 9999ohm, 1 ohm step Shell material: Plastic

MTester LCR-T4 12864 LCD

One day I got a cheap MTester from some Chinese source. MTester is a cheap electronics component measurement device. It can detect component types and measure them. 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
