Get the most benefit from your DDR4 and next generation memory designs DDR4 DRAM technology with fast data rates of 1600 MT/s and higher forced the industry to adopt high speed serial interface testing methodologies. Traditional setup and hold time tests are now replaced with eye diagrams and mask tests to account for bit error rate. Many DDR4… (Show moreShow less)
Power Quality Determines the Performance of Your Device Your product’s functional reliability is directly proportional to the quality of the DC power inside your product. Intuitively this makes sense: Stable DC supplies should not cause issues. Unstable DC supplies can cause unreliable performance. In today’s products, IC density is increasing… (Show moreShow less)
The diode is a crucial component to master if you want to grow your electronics prowess. So, it’s crucial to have a solid understanding of how diodes behave under varying loads. Today we’re going to look at some diode fundamentals, then take a look at a video covering 4 ½ practical uses for a diode. What are Diodes? Diodes are relatively simple… (Show moreShow less)
Did you know that when you probe your DUT, the probe becomes part of the circuit? All probes have a loading effect on your circuit to some extent. These effects can manifest into overshoot, ringing, slow rise/fall times, propagation delays and DC offset problems. In addition, the loading impacts vary as you probe from DC voltages through high… (Show moreShow less)
The terms “bit error rate” and “bit error ratio” are used interchangeably on many websites and publications. However, the definitions are very different. Understanding the difference will help you effectively analyze your system’s performance. What is a BERT? To find the bit error rate or bit error ratio of your system, you need a Bit Error Rate… (Show moreShow less)
You just bought a high frequency single-ended and differential probe and are feeling good about your measurements. But when using the two probes side-by-side, you notice differences in vertical voltage measurements and rising edge times. This can cause you to question the accuracy of your measurements relative to what your device under test (DUT)… (Show moreShow less)
Many people think that differential probes are made to only probe differential signals. Did you know you can also probe single-ended signals with your differential probe? Today we’ll learn how to maximize the usage of your differential probe and get the best signal fidelity possible. You will need to examine the performance and usability… (Show moreShow less)
Did you know that when you probe a circuit, you change the electrical characteristics of that circuit? Oscilloscope probes add resistive, capacitive, and inductive loads to your circuit. These loading affects can change the operation of your circuit under test. Understanding these loading impacts helps you avoid selecting the wrong probe for your… (Show moreShow less)
Bandwidth is one of the key oscilloscope probe banner specifications, and if you pick the wrong bandwidth, you’ll get inaccurate measurements. However, picking the right bandwidth probe isn’t as simple as you might think. Avoid making these common mistakes when selecting the right probe bandwidth, and have confidence that the signal you measure is… (Show moreShow less)
Knowing key Arbitrary Waveform Generator (AWG) specifications lets you make the best purchase decision, saving you time and money. Learn how to compare these characteristics across arbitrary waveform generator types and vendors: memory, sample rate, dynamic range, and bandwidth. Let’s discuss these specifications in detail. Memory Size Memory… (Show moreShow less)
