A big question that you might have is, what is the difference between Pre-Compliance and Compliance testing?  What makes Pre-Compliance important?  Pre-Compliance is a low risk, cost effective method to ensure your DUT will pass final Compliance testing.  Waiting until the end of a product development cycle for compliance testing is risky due to… (Show more)

There are two kinds of EMC Pre-Compliance tests you can perform – radiated and conducted.  Today, we will review conducted emissions testing – what it is and why it’s important.  For a similar discussion on radiated testing, check out EMC Basics:  What is Radiated Emissions & Immunity Testing?.   Conducted emissions tests focus on the unwanted… (Show more)
After reading my last blog you’ve been given a brief intro on What are EMC & EMI Measurements and why it is important to measure for to ensure your device is pre-compliant.   In this blog we’ll discuss 2 of the 4 EMC pre-compliance tests – radiated tests, emissions and immunity – in more detail.   Radiated Testing Radiated tests, as mentioned… (Show more)
Introduction: Conceptualizing your next product, designing it, and then releasing it to market are more or less the main phases encountered during a product development cycle. But what if you had gotten as far as finishing your product design only to discover late that you cannot push the product to market, because it didn’t meet some standards… (Show more)
Prove yourself as an engineer! The Schematic Challenge is the perfect opportunity to test your skills. On March 12, 13, and 14, we will be posting a new schematic or problem-solving challenge. If you, as a community, are able to answer questions 4, 5, and 6 correctly by Thursday, March 15 at 11:59 PM MST, we will add three 1000 X-Series… (Show more)
You have your workspace set up with your oscilloscope, waveform generator, and vector network analyzer. Now all you're missing is some desk space to actually do your work. What if I told you that you could get the same performance from machines half the size of your current setup? Small form factor equipment is a great option for labs where space,… (Show more)
In the previous edition of The Four Ws, I reviewed the fundamentals of adjacent channel power (ACP). This time I’m discussing the WHAT, WHY, WHEN and WHERE of harmonic distortion measurements. Measuring harmonic distortion will help you validate the proper functioning of your device’s components and, in turn, avoid interference with systems… (Show more)
This week’s post is guest authored by Charlie Slater, Business Development and Operations Manager for Keysight Services.   These days, most organizations operate within one of two scenarios: cutting costs while delivering the same topline, or holding costs steady while increasing revenues. The third, less-common scenario is investing more to… (Show more)
In a rock band, the drummer keeps the beat steady and the other musicians follow the rhythm. The drummer keeps the entire band in synch. The same concept is true when you integrate multiple instruments into a test system. The individual instruments need to be synchronized, especially when you are making multi-channel RF measurements. Like a… (Show more)
Originally posted Sept 25, 2013   Understanding when the errors will become a problem In this space, we’ve already talked about how the universe may be noisier than you think and described how noise adds something to all signal measurements. The Grinch’s distaste for noise was understandable, but it’s hardly a strategy for making better… (Show more)
