The analysis of RF and microwave signals in the frequency domain used to be the forte of the spectrum analyzer, but now it’s become a choice between signal analyzers and digital oscilloscopes. How did this happen? What’s the difference? How how do we choose? Let’s take a look.
Promising Future Ahead For Spectrum Analyzer Market
The spectrum analyzer markets has grown rapidly for the past couple of years. The huge demand for wireless technology, in combination with better bandwidth and frequency, as well the use of portable and handheld analyzers, are important drivers behind the growth.
This article lays out key trends in the Spectrum Analyzer market, such as an increased demand for secondhand spectrum analyzers.
Spectrum analyzers are a handy tool that analyze signal frequencies and amplitude on a logarithmic scale when an electrical signal passes through the device’s system. Over the years, spectrum analyzers have become widely used in industries like manufacturing, designing, and even in services involving repairs, determining performance, along with detecting and troubleshooting errors of electrical devices.
The process of measuring modulation quality is implemented for smooth data transmission, which is critical on both the transmission and receiver end. Some important spectrum analyzer characteristics to complement this facet of a spectrum analyzer’s functions are signal-to-noise ratio, along with noise figure tests, all of which improve the overall performance of the system.
Your Guide to Buying Network Analyzers
What information do you need and what factors should you take into consideration when buying a network analyzer? This guide walks you through.
In order to choose the right network analyzer for a given application, it is necessary for buyers to understand the demands of the electrical network they will be working with.
Simple electrical networks that must measure amplitude alone can use a basic SNA-type network analyzer. Moderate to complex electrical networks that require measuring amplitude properties and phase properties require a VNA-type network analyzer. Complex electrical networks that must measure harmonics require a MTA or LSNA-type network analyzer.

What's awful about being a software engineer, tech lead and manager?
"I work really hard and then someone tells me to redo it".
Most of the times you might love your job. But then there are certain things that can make you feel like switching career at that very moment.
Here is an overview of the downsides of being a software engineer, tech leach or manager.
I've been building software professionally for over 10 years now. I love what I do and I hope to be an old programmer someday. But along the way, I've encountered many terrible things that have made me hate my job. I wish that someone had given me a roadmap of what to expect earlier in my career, so when some new and unfortunate awfulness occurred that I wouldn't have felt so alone and frustrated.
This post is meant to be such a guide.
Physicists open the door to the first direct measurement of Berry curvature in solid matter
Measurement takes all forms and is important in everything we do.
UC Santa Barbara physicists have opened the door to the first direct measurement of Berry curvature in solid matter. Their work, published in the journal Physical Review X, builds on a previous UCSB paper in which they describe experiments resulting in an electron-hole recollision achieved by aiming high- and low-frequency laser beams at a semiconductor made of gallium arsenide.
BGU Researchers Crack the Code of Invisibility
A team has found a way to manipulate light to render an object invisible. Learn more about the opportunities this breakthrough opens up for.
The Jerusalem Post – BGU researchers have made a breakthrough in manipulating light to render an object, such as an optical chip, invisible.
According to the recent study published in Nature Scientific Reports, the researchers invented a new method that deflects and scatters light away from the “cloaking” chip’s surface so it is not detected.
Keeping pace with increasingly intelligent machines
As embedded devices become more advanced, engineers are facing significant challenges to ensuring the quality of these on time and on budget.
To keep pace with this rapidly evolving complexity while also ensuring safe, high-quality vehicles, development teams must evolve the methods organizations use to design and validate embedded software.
A modern automobile has millions of lines of code, which can range in functionality from engine control to navigation to automated seat adjustment. While no off-highway vehicle currently incorporates this many ECUs, National Instruments is quite sure this level of software integration is most certainly on the horizon for agriculture and construction equipment.
Everyone who has used a webpage, phone app, or other consumer software product is aware that errors in software are common and expected. The challenge is that in the consumer space, these errors are typically resolved with a quick reset of the application with relatively little impact to the user (lost data excluded).
However, when this paradigm is applied to an electromechanical system these errors can have catastrophic consequences if they are present when the customer operates the machine.
Create a Halloween Pumpkin Like a NASA Engineer
NASA's engineers are sharing some creative ideas of how to design a pumpkin that will be noticed by your neighbors.
Want to make an out-of-this-world Halloween pumpkin? Take a cue from the engineers at NASA’s Jet Propulsion Laboratory. It’s their job to design and build robots that can travel millions of miles to study other planets – and sometimes even land and drive around on the surface.
So on Halloween, they can’t help but bring some of that same creative thinking to designing stellar pumpkins inspired by space exploration.
Will IoT Sensors Lead to Test Headaches?
Have you experienced too much IoT-like sensor information causing false alarms, and subsequent unnecessary shutdowns of the system, or just ignoring of all alarms?
The number and types of sensors are growing significantly. EE Times discusses how this also could result in many unforeseen system-oversight implications.
"As any experienced engineer knows, sensors are the most vulnerable part of a system. Due to their inherent role, sensors are exposed to the nasty real world of moisture, vibration, temperature, and other physical stresses to a lesser or greater extent. Sometimes the exposure is directly due to what is being monitored, but often it is a side effect of monitoring some other parameter. Regardless of the cause, sensors live a much harder life than the electronics on the typical PC board, even if that board is in an automotive environment.
The problem is that as we add IoT sensors to everything, we'll be seeing more false positives and negatives that will be harder and harder to test and assess. Soon, planning for how to test the veracity and credibility of the many readings and alarm indicators will become a larger part of the project."
Simple Transient-Response Measurement Determines Power-Supply Bandwidth
Ascertaining the relationship between bandwidth and response in power supplies isn’t easy, but this idea for design presents a measurement approach that helps ease the process.
It’s normal to assume that there’s an easy way to relate the bandwidth of a power-supply control loop to its transient response—no good reference exists that defines this in simple terms. It seems like a straightforward problem, which should have a simple solution. The higher the bandwidth, the faster the loop responds, and with less voltage deviation.
It's not always that straight forward, however.
What Every Engineer Should Know about Oscilloscope Probes: Passive vs Active
Do you have a random stock of probes on your bench? Probe selection can seem confusing at times and it's also proven that the choice significantly can affect your measurement.
This guide will walk you through the first step to better, more accurate measurements.
I’ll bet you have quite the stock of random probes on your bench. And, you’ve inevitably reached for a probe and made a measurement without even knowing which probe you were using. I’m guilty, too. Probe selection can seem awfully confusing, so we often resort to this “random selection.”
The fact is, probe selection can significantly affect your measurement, so let’s break this down and walk through the one simple thing every engineer should know about oscilloscope probes: what the difference is between passive and active. Use this guide as the first step to better, more accurate measurements.
