What You Should Know About Stratum System Levels

Posted by Rob Rutkowski on Sep 18, 2018 9:55:30 AM

What You should know about stratum levels graphic

When it comes to stratum levels and minimum performance requirements for digital network synchronization, there's definitely a lot to know. A standard first released in 1987 entitled "Synchronization Interface Standards for Digital Networks" from the American National Standards Institute (ANSI) lays out all the official information and requirements.

How OCXOs Establish Precise Frequency Control

Posted by Bliley Technologies on Apr 3, 2018 6:30:00 AM

RF engineers are aware that temperature variations are the most significant factor contributing to frequency drift in crystal oscillators. Other variables affecting frequency output, such as humidity and pressure, can be easily alleviated with a hermetically sealed packaging of the crystal in a vacuum, or in an inert gas such as nitrogen. Controlling temperature for precise frequency output in a crystal oscillator circuit, however, requires a higher level of electronic RF design ingenuity. Enter... The Oven Controlled Crystal Oscillator (OCXO).

Common Misconceptions About Crystal Oscillator Stability

Posted by Bliley Technologies on Feb 27, 2018 6:30:00 AM

RF engineers would love to get their hands on ideal crystal oscillator circuits. That is, a quartz crystal oscillator that transmits at the designated frequency for the entire life of the device without any frequency deviation. Unfortunately, that ideal circuit world is a mathematical fantasy.

There are many factors that contribute to quartz oscillator stability and frequency drift issues. To prevent these problems as much as possible, having a firm understanding of precise frequency stability will help give you the tools to keep your applications performing optimally. But there's another problem...

7 Incredibly Effective Ways to Prevent Pressure Transducer Problems

Posted by Rob Rutkowski on Feb 19, 2018 8:28:00 AM

Poor manufacturing environments can significantly reduce the performance quality of a pressure transducer. A failing pressure transducer will lead to problems with sensors and will provide inaccurate readings (or none at all).

A faulty pressure transducer not only can cause frustration and wasted time, but can also lead to unnecessary costs.

To prevent pressure transducer problems or failure from happening in the first place, let's take a look at 7 pressure transducer troubleshooting methods to keep your transducers & sensors working great!

How Well Do You Know RADAR?

Posted by Bliley Technologies on Jan 2, 2018 6:30:00 AM

When radar was first used in combat, it represented what is known as a “Revolution in Military Affairs” (RMA), a term used to describe a tactical, doctrinal, strategic, or in this case, technological change in military theory and activity that fundamentally changes the nature of warfare. World War II saw the first widespread use of radar on both sides of a conflict, and led to the emergence of electronic warfare as a method of counteracting the other side’s radar abilities while defending the friendly use of the electromagnetic spectrum. This competition spawned the evolution of many different radar functions for specialized applications. This article will explore various types of radar systems that exist and the functions they serve.
