Scope ADC Resolution is Nothing Without Good Probes Thursday, September 19, 2024
Key Factors Determining the Accuracy of Electrical Signal Measurement Measurement accuracy is often misunderstood as being solely dependent on the specifications of the instrument, such as the number of waveforms displayed on its screen. However, true accuracy is much more complex. It is closely tied to how well the measurement setup preserves the integrity of the signal being measured. The …

Test and Measurement in the Quantum Era Wednesday, July 17, 2024
From an engineer’s perspective the continuous advancement of quantum hardware and technologies is amazing. My interest began with curiosity about quantum physics. Now that curiosity is expanding as I gain a deeper understanding of the test processes, principles and criteria being used by these emerging technologies and how Tektronix can serve them. But let’s start at the beginning. A Growing …

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 …

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 …

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 …
