5 Parameters for Measuring Radar Pulses Friday, September 18, 2020
Radar systems can use continuous wave (CW) signals or, more commonly, low duty-cycle pulsed signals. Although there are several continuous transmission types of radar, primarily Doppler, the great majority of radars are pulsed. The RF pulse characteristics reveal a great deal about a radar's capability. Electronic Warfare (EW) and Electronic lntelligence (ELINT) experts specialize in the study of …

What is Probability of Intercept (POI) and Why it Matters Thursday, September 10, 2020
One term we see quite often when breaking down spectrum analyzers is probability of intercept (POI). So, what is the definition of probability of intercept and why does it matter? When we see “probability of intercept” we should know that this term is almost always a contraction of the phrase “minimum event duration for 100% probability of intercept”. POI is the amount of time equal to “the …

8 Challenges with Wideband Radar Thursday, August 27, 2020
Increasingly, designers of radar and electronic warfare (EW) systems and components need to perform modulation and pulse analyses at wider bandwidths. Spectrum managers also need to record and analyze hours of wide bandwidth data. There area number of test and measurement challenges associated with these needs, however.    Here are eight challenges with wideband radar: Generating …
A Better Method for Analyzing Ripple on Power Rails Friday, July 17, 2020
How Spectrum View Outperforms Traditional Oscilloscope FFTs with Tighter Frequency Resolution Over Wider Ranges Debugging embedded systems often involves looking for clues that are hard to discover just by looking at one domain at a time. The ability to view time and frequency domains simultaneously can enable you to measure a power rail’s voltage during wireless transmissions or observe nearfield …
An Introduction to Using Phasor Diagrams on Oscilloscopes for 3-Phase Power Analysis Wednesday, June 10, 2020
When you are working with 3-phase systems, having phasor diagrams available on your oscilloscope can save time during setup and provide faster insight into your system. In general, alternating voltages or currents are represented graphically as voltage or current versus time waveforms. This is the traditional oscilloscope view. A three-phase system consists of three sinusoidal AC voltages and …
3 Series MDO Users: 7 Enhancements You Can Get for Free Thursday, May 14, 2020
Some firmware releases are mostly bug fixes and minor improvements, but the April 2020 firmware release for the 3 Series MDO is different. It provides a total of 11 major performance enhancements and capabilities, and 7 of these are the focus of this post. They include significant performance improvements, features that were requested by users of the popular MDO3000 Series, and additional value …
Making Higher Accuracy Oscilloscope Measurements Thursday, April 23, 2020
One of the most important functional blocks in a digital oscilloscope is the analog-to-digital converter or ADC. This blog post explains why ADC resolution (number of bits) has become a more important consideration in oscilloscopes, especially for measuring small signal details. ADC Resolution FIGURE 1. A generalized signal flow through a digital oscilloscope   Many high-precision instruments …
How Keithley’s New 2601B-PULSE Can Help Vertical Cavity Surface Emitting Laser (VCSEL) Designers Save More Lives Tuesday, April 21, 2020
It’s late at night and you’re driving home. You’re tired and just want to get to bed. But then, all of a sudden, you are faced with a big animal in the middle of the road. Immediately, your car slams on the brakes to prevent you from hitting the animal and from swerving off the road. Through the technology of light detection and ranging – better known as LIDAR, your vehicle has protected you from …

Troubleshooting EMI – 2 Tips and a Case Study Tuesday, April 7, 2020
Your design is exceeding the radiated emissions allowed by EMC regulations, now what? Whether you’re performing pre-compliance testing or troubleshooting a failed formal compliance test, our latest generation oscilloscopes make what was once an overwhelming task far simpler and more straightforward. Below are two helpful tips and a case study to help you troubleshoot EMI. For an even deeper dive …
Tektronix 4 Series MSO vs Keysight 4000A X-Series Oscilloscopes Thursday, April 2, 2020
In this blog I will talk about the operational similarities and differences between the Tektronix 4 Series MSO and the Keysight 4000A X-Series oscilloscopes. I will be looking at not only datasheets, but instrument user guides as well. User guides can be lengthy to explore, but they provide a wealth of information on instrument settings and limitations that you may not be aware of after reading …
