EE / RF / EO – covering the full spectrum
If you’ve landed on this page, chances are you already have a good idea what a waveform or signal generator does and why you’d need one. You may even be close to deciding on a new unit for your lab. If so, you’ve come to the right place!
We’ve compiled a list of 5 great signal generators, and they cover all different price points, so there’s bound to be something for every budget.
Read MoreIntroducing a new SDR radio bundle specifically designed for tuning into weather satellite signals.
Using an SDR to receive weather data from NOAA’s GOES satellite constellation is one of the most common applications for software defined radio enthusiast. There are a ton of tutorials and videos on how to setup your SDR rig, antenna, and SDR software to receive and decode weather images.
One thing that can slow folks down on their quest for home-brew meteorology is figuring out just what equipment is needed beyond a great SDR radio. There are antennas, LNAs, filters, etc. It can all become a bit overwhelming at times.
That’s where a new SDR bundle from Nooelec comes in. The folks over at Nooelec have taken all the guess work and hours of sifting through forums out of designing the best SDR weather station. They’ve created a bundle that includes everything you need to receive weather satellite images.
Read MoreOne common piece of test equipment in any RF laboratory is the signal generator. The purpose of these devices is in the name itself “signal generator,” in that it generates signals with tunable properties such as amplitude, frequency, and wave shape. Signal generators are also called function generators, although, function generators often have more advanced features.
Signal generators are most commonly used to test the response of circuits using known and controllable input signal. In order to validate the output signal coming from the function generator it is common to validate that signal with an oscilloscope (but that’s the topic of a future post).

You’ve scoured all the blogs and forums and finally decided on a great new software defined radio (SDR) rig… now what?!? Choosing your first SDR project can seem daunting, not to mention some of the most interesting signals may seem relatively obscure or unknown if you’re new to software defined radios.
We’ve compiled a list of the most popular aviation related waveforms and signals to explore with your SDR. Before building a new SDR project, be sure to confirm your radio has the appropriate bandwidth and frequency range to detect the signals listed below. Without further ado…

One of the most essential pieces of test equipment for any electronics lab is the multimeter. Today, multimeters are typically all digital and are referred to as Digital Multimeters or DMMs. Choosing the right digital multimeter can be daunting since the DMM is one of the most used pieces of equipment in the lab.
Digital multi-meters can be portable or benchtop. For this article, we’ll focus on benchtop multimeters suitable for use in a typical electronics lab. As the name implies, benchtop multimeters are used to measure multiple fundamental electronics measurements. The most basic measurements include measuring voltage, current, and resistance. More advanced benchtop digital multimeters can also measure things like capacitance, inductance, conductance, frequency, duty cycle, diode drops, etc.

So what is the best SDR receiver or transceiver in 2021? The answer is… it’s complicated! When picking an SDR radio, there are many factors that come into play; frequency ranges, transmit/receive capability, complexity, available firmware and open source projects, and of course cost! The following list of great SDR radios covers this diverse spectrum and we hope any one interested in software defined radios will find something that will work for them.
Read MoreSoftware Defined Radios or SDRs offer a high level of flexibility and adaptability compared to traditional hardware based radios. However adding all these 1s and 0s to the already complex and beautiful art of MHz and dBs can be daunting. We wrote this post to help you start your journey using software defined radios (SDRs) in 5 simple steps.
If you’re scratching your head wondering “what the heck are SDR radios or software defined radios anyways?!?” check out this post that describes SDR radios compared to traditional radios.
Without further delay, here is our beginner’s guide to get started using software defined radios!
Read MoreIn this post we’ll explore SDR radios or software defined radios. There’s been a common theme in most things technology related lately and that is a move to Software Defined Everything, or SDx as it is often shortened. Radios and RF communications equipment in general have been moving toward a software-defined existence just the same.
A radio is any kind of electronic device that transmits and receives signals in the radio frequency (RF) portion of the electromagnetic spectrum. These signals (often called waveforms) are used to transfer information between radios. Radios are ubiquitous today and found in almost every electronic device you own thanks to the proliferation of “smart” and “connected” devices.
