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 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.
5G Wireless is Right Around the Corner thanks to mmWave
Fifth generation wireless systems are not far from becoming a reality, thanks to recent research being done on the millimeter wave (mmWave) radio spectrum.
Experts agree the way forward is to manufacture mass deployable wireless devices across a range of markets and for different applications. Among other things, these applications include mobile computing and data processing over networks. The technology also has applications in the field of medicine and healthcare.
Maintaining strong frequency stability in electronic RF circuits by eliminating phase noise is important in many high-end communication applications. This is especially true for precise targeting in radar systems and spectral purity in other communication systems.
Let's take a deep dive into exactly what phase noise and jitter mean. This will help give you a better idea as to why reducing a system's phase noise is significant.
What Is Phase Noise?
In the simplest terms, phase noise describes the stability of an oscillator in the Frequency Domain, while jitter describes stability in the Time Domain.
A Simple 5-Step Path to Understanding Phase Noise
Step 1: Spectral Density
Step 2: When plotting each spectral density point at varied frequency intervals of your choosing (In this case every 1Hz), you're left with a graph that looks like this:
Step 2: Signal Power Density
You are now looking at what is known as the Signal Power Density of the noise.
Now focus only on the upper sideband of the graph from fstart to fstop, this is called the "Single Side Band".
Step 3: Noise Power Density
We can now refer to the plotted part of the single side band as noise (Anything above the nominal oscillator frequency (Fosc) and not harmonically related can be considered phase noise). The technical term for this part of our graph is Noise Power Density (Step 3). We measure noise power density in dBW (LOG(Watts)) at this point because of the large range which we are looking.
Step 4: SSB Noise Density
Step 5: Phase Noise
What Causes Phase Noise?
- High vibrations
- Micro vibrations
- g forces and acceleration sensitivity

As the name implies, the digital multimeter is useful for a wide range of measurements and tests. Bench top digital multimeters, or DMMs, can be used to to make the basic (Ohm’s Law) measurements:
- Measure resistance
- Measure voltage
- Measure current
Finding the Best Performing Engineering Laptop
Our engineering team at Bliley is growing, which is great, but it also introduces some new challenges for small business like ours... finding the best performing engineering laptops for our engineers.
We want to give our engineers the best tools available and create an environment where they can be their most innovative and do the best work of their careers. Of course, a key to this whole equation is the technology they use day-to-day to get those next generations products designed. We recently kicked off a search for the best laptops that are perfect for engineering workloads. As you can probably imagine, the ideal laptop for an engineer needs to have great compute and graphics power.
RF and Microwave Design can be ENJOYABLE...
Don't believe me? Many of us already know how designing can easily become extremely long, boring, and tedious. This is especially true for all you RF and Microwave Design Engineers!
Spending hours upon hours designing, finding problems, fixing problems, then repeating the process all over again...It all can become so mentally draining.
Am I bringing back bad memories? Sorry, time for the good news...
So how can you make the long and tedious design process easy (and possibly even enjoyable)?
You guessed it... Automation and design tools are key.
Having some great CAD tools on your side can release a significant burden off your back. These tools can save you time and dramatically increase your productivity. Our Top 4 Productivity and collaboration tools will help skyrocket your productivity even further.
Today, we thought we'd help you out by sharing these 18 CAD design tools that can lead to a more simple & enjoyable design session.
Without further adu, here is our list of engineering thought leaders that you should be following on Twitter.
As electronics and RF systems have become increasingly complex, the need to catch and fix errors during the design phase of a project has become increasingly important.
Catching an error during the design phase is orders of magnitude less expensive to fix than catching it during the manufacturing or test phases.
RF engineering is a branch of Electrical Engineering involving the use of electrical magnetic frequency properties to produce products that will transmit or receive these frequencies.
RF engineers can face a lot of challenges and frustration. This frustration can be caused from all the discrepancies and complex maps of components used in RF circuits.
In order to be a successful RF engineer, a few habits and processes can be formed. Here are 10 critical tips to be an efficient RF engineer.
