TBS1000C bench oscilloscope
How to choose the best oscilloscope Tuesday, May 11, 2021
Oscilloscope bandwidth System bandwidth determines an oscilloscope’s ability to measure a signal. Specifically it determines the maximum frequency that the instrument can accurately measure. Bandwidth is also a key determining factor in price. Determine what you need – use the ‘five times rule’ For example, a 100 MHz oscilloscope is usually guaranteed to have less than 30% attenuation at 100 MHz …

What is an oscilloscope? Tuesday, May 11, 2021
An oscilloscope, formerly known as an oscillograph, 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 microphone is a sensor that converts sound into an …

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 …

How Does the New Generation Memory – DDR5 – Change Things? Monday, May 3, 2021
From augmented reality to artificial intelligence, cloud computing to IoT, 5G is fueling growth in new technologies – and the data they create. With more and more data comes the need for storage and fast access which means that technology like DDR5 has never been more important. The need for data centers to continuously store, transfer and process this data pushes the limits of high-speed …
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 …

How Does an Oscilloscope Measure Frequency? Tuesday, April 6, 2021
Oscilloscopes measure the voltage of an electrical signal, which is then graphically represented by waveforms. However, an oscilloscope can be used to take measurements for a number of different applications – one of which is frequency. But how does an oscilloscope measure frequency, exactly? Well, there’s a straightforward answer, and then there’s a slightly more complicated answer. On most, if …

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 …

Bench Power Supply Basics Thursday, April 1, 2021
A 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. 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 supply types How to choose the …

What does an oscilloscope measure? Thursday, March 25, 2021
Most consumer products include electronic circuits or components, and an oscilloscope is used throughout the product design process to test those components. But what is an oscilloscope? And what does an oscilloscope measure? An oscilloscope is an instrument that graphically displays electrical signals and shows how those signals change over time. Engineers use oscilloscopes to measure electrical …

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 …
