Why is uninterruptible power supply so important

Why is uninterruptible power supply so important?

An uninterruptible power supply (also called UPS) is a very complex unit that is used for protecting certain devices from power spikes, power outages, while also offering backup capabilities, a backup battery in our case. The backup battery can keep supplying any device connected to

Make your own Phased Matched cables with NanoVNA

Phase matched cables come handy when dealing with phasing elements of an antenna or even when you want to deliver differential signals. There was a time when making phase matched cables meant use of expensive vector network analyzers. With the NanoVNA on your desk, you

Measuring noise figure using Gain Method

For those into radio astronomy would know the significance of having ultra-low noise figures. Lower the noise figure, the more sensitive your receiver becomes. Noise figure is a unit of measure that tells us how much noise, for example, your amplifier is adding to the

Accurately measuring cable length with NanoVNA

Update: Now you can plot the impedance vs. distance/time plot. Click here to learn the concept. Original Post: Having a VNA opens up so many possibilities. Just last week, I reviewed the nanoVNA and found to be an interesting device to have. Having handled expensive
