EE / RF / EO – covering the full spectrum
In RF engineering, Bode plots are used to analyze the frequency response of RF circuits and systems. They can be used to design and optimize the performance of RF amplifiers, filters, and other RF components such as software defined radios.
A Bode plot is typically made up of two plots: a magnitude plot and a phase plot. The magnitude plot shows the gain of the system at different frequencies, while the phase plot shows the phase shift of the system at different frequencies.

There are a few pieces of RF test equipment that are absolutely essential. In no particular order, the top 3 most important pieces of test equipment are an adjustable DC power supply, high quality digital multimeter, and a good oscilloscope. In this post we share 22 of the best oscilloscopes (or oscopes) available today (2022 Edition).

Read MoreIf there was a singular piece of test equipment that is absolutely vital, it would have to be a great DC power supply. This humble little box was the topic of a recent “Ultimate Guide to DC Power Supplies” post we did. At the end of that post, there were a handful of top DC power supply options that are extremely powerful. Given the importance and sheer range of options we wanted to do a dedicated list post to cover a broader set of DC power supply options.
To that end, we compiled a list of 21 great DC power supply options below.

Read MoreSoftware Defined Radios (SDRs) are become more and more popular. This is partially due to the wide availability of low cost USB dongle SDR radios based on RTL2832U demodulator chipset. This is where the “RTL” in RTL-SDR comes from. While these low cost SDRs are not as capable as some of the higher performance SDR radios, they do offer a good bang for the buck. In this post we’ll take a look at 17 great RTL-SDR dongles.

A good, low-noise power supply is an essential piece of test equipment whether you’re testing analog circuits, like audio amplifiers, digital circuits, like a new Arduino board, or RF circuits, like a new SDR radio. These vital pieces of test equipment supply clean voltages to your devices under test while having the option to limit things like current draw. There are many other protections built into the best DC power supplies, but these are often listed on spec sheets as confusing acronyms. In this post we will run through 10 common acronyms associated with power supplies and explain each of them in layman’s terms.
Let’s jump right in!

A multimeter or digital multimeter (DMM) is one of the most essential and common pieces of lab equipment. Multimeters are used for taking basic electrical measurements related to Ohm’s Law. This includes measurements like voltage, current, resistance, etc. Multimeters can be both handheld or benchtop units. Benchtop multimeters tend to offer higher precision than their smaller handheld counterparts. For this purpose of this article, we’ll assume a benchtop multimeter is being used.
Without further ado, here is an explanation of every multimeter measurement.

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.
