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...

Comparing NanoVNA with the Keysight Fieldfox N9952A
Vector network analysers (VNA) come in all sort of price ranges. Most of them are out of reach for a typical hobbyist. Very few VNAs are available to be bought by someone like you...
NanoVNA – A short review
Do you build RF circuits? Have you built any antennas? If the answer to any of the two questions is YES, then you know how valuable having a VNA (Vector Network Analyzer) is. Just...
Using LimeSDR mini as a RF source
In one of the previous posts we saw how we could transmit DATV using LimeSDR mini. This time we are going to use our LimeSDR mini as a RF source in our home lab....
RF Pulse generation with RF switch
Remember the previous post where we generated PWM? We are going to use the PWM output from the TivaC microcontroller and drive an RF switch. I will be using the Minicircuits HSWA2-63DR+ SP2T switch...
Getting LimeSDR Mini to work for the first time
LimeSDR is a real temptation to buy if you are an RF or a signal processing guy. We all know FPGAs give you a huge set of building blocks of the digital world and...
