What’s The Difference Between…

Amongst the dozens of serial interfaces in use today, the older ones are still widely deployed, especially in the industrial control field....More

The path to digitalization for both real-time and sampling scopes is essentially the same. The input signal passes through front-end signal conditioning circuitry on the oscilloscope and is digitized, stored to memory, and then displayed on screen. However, the underlying technology for each varies dramatically....More

Market acceptance of USB 3.0 has been increasing steadily because of its many advantages. USB 3.0 hubs maintain compatibility with USB 2.0 but add functionality....More

Many tests require supplying a varying voltage or current to a device under test or unit under test and making a voltage or current measurement. A typical example is plotting the I-V curve of a diode. One way to perform this test is to use a power supply to provide the source and a DMM to make the measurement. Another way to perform it is to use a source measurement unit instrument or SMU. So, what’s the difference between the two approaches?...More
