Inside Frequency Control

Do you know all about atomic clocks in space and how they work? If not, it's about TIME you do. (Haha. Ha. Ha...)

Timing is everything when it comes to GPS satellites and other space applications. Even just a one-microsecond error in timing can lead to an error of 300 meters on the ground. Because atomic clocks can maintain very precise timing, they're a great solution for GPS and other LEO satellites.

GPS disciplined oscillators (GPSDO) are some of today's most trusted and accurate sources of timing. These powerful devices (sometimes called GPS clocks) consist of a high-quality stable oscillator and a GPS receiver. The GPSDO works by disciplining (or steering) the oscillator output to a GPS device or GNSS satellite signal via a tracking loop.

Surface acoustic wave (SAW) filters offer a reduced size, weight, and cost compared to other filter technologies. There are many tradeoffs, however, that need to be considered when selecting a SAW filter for your system design.

What are SAW filters? What are some common SAW filter applications? How are SAW filters used for mobile communications? We'll answer these questions and more in this post.

“Good things come to those who wait,” as the saying goes, and while aging is a part of all life cycles, crystals shouldn’t age prematurely. The careful production stages and the time it takes to complete them are necessary to the efficient operation of OCXOs. 

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.

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. 

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?

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. 

Hi there! You must be looking to upgrade your engineering electronics lab with the latest and greatest test equipment on the market today. Well good news...this is the place to be! Cool engineers only please...meaning all of you.

Do you find it difficult to identify what RF connector type you're going to use in an application? If so, don’t worry. In this article, you will learn about the different types of RF connectors and what applications they are commonly used for. 

RF (radio frequency) connectors are connectors that are designed to work at radio frequencies for signal transmission of products like radios, antennas, coaxial cables, etc. However, these connectors have a variety of types. 

Here are 5 of the most commonly used types of RF connectors.
