Inside Frequency Control

One of the most common pieces of test equipment for any electronics lab is oscilloscopes.  Oscilloscopes, or o-scopes for short, are versatile pieces of test equipment that can be used in a multitude of different critical measurements.  While oscilloscopes are standard in almost every electronics lab, they come in many different shapes, sizes, and price points.

When trying to select the best oscilloscope for your electronics lab, it's important to understand which features drive the cost of the o-scope the most.  For example, one of the biggest cost drivers for oscilloscopes is the device's measurement bandwidth.  An o-scope that has a narrow bandwidth of 200 MHz can go for a few hundred dollars; however, a top-of-the-line oscilloscope with a measurement bandwidth of 1 GHz can go for almost $30,000!

We have done all the research and read all the reviews for more oscilloscopes than we'd be willing to admit.  We've done all this leg-work so you don't have to.  So without further ado, here is our list of the 3 best digital oscilloscopes for any budget.

Before we dive into the differences between the 5 GNSS constellations... It's important that we're all on the same page with the difference between GNSS and GPS.

Many people get GNSS and GPS technology confused. A good way to think about the Global Navigation Satellite Systems (GNSS) is as the backbone (or underlying technology) behind GPS. The Global Positioning System (GPS) GPS is a GNSS constellation, but GNSS is not always GPS. GPS is one of the 5 GNSS constellations used around the world.

The 5 GNSS constellations include GPS (US), QZSS (Japan), BEIDOU (China), GALILEO (EU), and GLONASS (Russia). We'll cover each of these constellations in-depth in this post.

If you’re reading this, you’re about to discover 10 of the best productivity tools that we either use here at Bliley, or that we might use in the future! We feel these tools will help keep you organized, improve communication among your coworkers, and of course, make you the most productive worker possible.

I have a feeling you're in need of some new test equipment... a new signal generator to be exact. If so, you've come to the right place. Maybe your current signal generator is outdated. Or maybe you're looking for your first one (in which case we'd be honored). 

No matter the reason, we wanted to share with you the best selection of waveform signal generators on the market today to help you make the best purchase based on your needs.

Back in 2016, we wrote one of our most popular posts covering 12 popular Software Defined Radios or SDRs.  While the previous post still holds some extremely valuable information, a lot has changed... especially the technology related to SDR. So we thought it was time for an update.

Like last time, we tried to include as much diversity in terms of prices, applications, frequencies, and ease of use.  Our hope is the perfect software defined radio for your application is on this list. 

The most important thing a soldier must maintain on the battlefield is Situational Awareness: being able to identify and understand what is happening around you and how it pertains to the mission. Over the past few decades, Global Positioning System (or GPS navigation technology) has become an integral tool for helping US forces stay aware of their surroundings. Now, new Positioning, Navigation, and Timing (PNT) technology is helping to enhance traditional GPS timing in many ways. Time to explore further!

From smartphones to satellite service, GPS and more, RF technology is a feature of modern life that is so ubiquitous that many of us simply take it for granted.

Radio frequency engineering continues to help drive the world across many applications in both the public and private sectors. But technology advances so fast, it’s sometimes hard to predict what the world will look like in just a few years. Back in 2000, how many people outside the industry would have guessed that within 10 years, they’d be watching streaming videos on their phone?

According to Statista,  there is a projected 30 billion Internet of Things (IoT) devices to be connected by 2020. That would be over a 400% increase in connected IoT devices from 2014. Most of these IoT devices will need to be connected through at least one type of wireless radio frequency (RF) communication.

Is your electronics lab in need of an upgrade? It's important to keep your equipment up to date with the latest and greatest technology to keep getting the best results (and therefore a more effective product). In this post, we're going to look at 6 spectrum analyzers that will work (and look) great in your lab. 

Quartz crystal oscillators are the high and mighty option for low phase noise and added frequency stability in circuit design. Yes, simple oscillators like those made with resistor-capacitor (RC) or inductor-capacitor (IC) resonators are fine for some circuits. But if you're dealing with higher performance applications in aerospace, military, and space industries... you're going to want a higher performance crystal oscillator that can maintain low phase noise & strong stability. Otherwise, you'll risk deviating from the very specific (and many times critical) center frequency selected for your design.
