Testing and Debugging PMICs with Ease Friday, September 22, 2023
Adaptive Power Optimization is Revolutionizing PMICs “There is no better way to save energy and cut bills than by turning all electronic devices off.” This basic piece of advice is the underlying principle and philosophy behind any form of energy management applied to energy consumption optimization, and in general in so-called adaptive power optimization. In the case of battery powered …
Energy Storage Devices: a Battery Testing overview Wednesday, July 28, 2021
Energy storage device testing is not the same as battery testing. There are, in fact, several devices that are able to convert chemical energy into electrical energy and store that energy, making it available when required. Capacitors are energy storage devices; they store electrical energy and deliver high specific power, being charged, and discharged in shorter time than batteries, yet with …
How to Measure a MOSFET I-V Curve
How to Measure a MOSFET I-V Curve Thursday, May 27, 2021
One of the best ways to ensure a MOSFET is functioning properly and meets specifications is to determine its characteristics by tracing I-V curves. There are a number of output characteristics requiring I-V tests; you can derive gate leakage, breakdown voltage, threshold voltage, transfer characteristics, and drain current all by simply tracing I-V characteristics and verifying the device is …

Bench Power Supply for Your Application Monday, May 17, 2021
A benchtop DC power supply is a standard piece of test and measurement equipment used by electrical engineers and circuit designers to power and test their circuit system designs in the lab and in the field. But what exactly does it do and how can you find the right bench power supply for your application? We’ll cover all that and more. Why do you need a bench power supply? Bench power …
2 Series MSO24 Mixed Signal Oscilloscope
How to Choose the Best Oscilloscope to Buy Tuesday, May 11, 2021
Basic Parameters for Choosing an Oscilloscope Oscilloscope Bandwidth Bandwidth is a key spec that determines the highest frequency your oscilloscope can measure accurately. It's a vital consideration affecting both the functionality and cost of the oscilloscope. The higher the bandwidth, the more accurate the reproduction of your signal, as illustrated with a signal captured at 250 MHz, 1 GHz …

What is an oscilloscope? Tuesday, May 11, 2021
An oscilloscope, formerly known as an oscillograph (informally scope, oscope, or o-scope), is an instrument that graphically displays electrical signals and shows how those signals change over time. It measures these signals by connecting with a sensor, which is a device that creates an electrical signal in response to physical stimuli like sound, light and heat. For instance, a …
Oscilloscope probe connected to a DUT
What is an Oscilloscope Probe? Monday, May 3, 2021
An oscilloscope probe is a device that makes a physical and electrical connection between a test point or signal source and an oscilloscope. Depending on your measurement needs, this connection can be made with something as simple as a length of wire or with something as sophisticated as an active differential probe. Essentially, a probe is some sort of device or network that connects the signal …
Types of signal generators
Types of signal generators Wednesday, April 28, 2021
A signal generator is an analog or digital device that engineers use to create electronic signals when testing circuit designs. There are many different types of signal generators with diverse features and applications. Below are the most common types of signal generators and the unique capabilities of each. Waveform or function generators Waveform generators produce electrical waveforms over a …
Chamber for an EMC/EMI precompliance test
The Financial Case for an EMI/EMC Pre-Compliance Test Solution Tuesday, April 20, 2021
Failing EMI compliance testing can be a design engineer’s worst nightmare. Additional compliance testing costs, external lab testing, debug engineering time, and in some cases, board spins can add significant costs and time delays to your project. Unfortunately, for companies new to EMI/EMC, estimating compliance testing cost can be somewhat challenging. In this blog, we’ll provide information on …

How to Measure Current with an Oscilloscope Tuesday, April 6, 2021
Though it’s not uncommon to measure current with a digital multimeter, measuring current that changes over time requires the use of an oscilloscope. Most oscilloscopes only directly measure voltage, not current, however you can measure current with an oscilloscope, using one of two methods. Measure the voltage dropped across a shunt resistor: Some power supply designs may have shunt resistors …
