Video: Zooming In On Waveforms

Many modern oscilloscopes offer the ability to zoom in on select portions of a waveform trace, allowing users a much more detailed look at whatever anomalies may (or may not) be present. Zooming is a handy feature on any oscilloscope, but it's even handier if you happen to be using a Teledyne LeCroy HDO. These instruments bring 12 bits of vertical resolution to the table for even more detail and cleaner, crisper waveforms than any legacy 8-bit oscilloscope.

So, without further delay, here's a short tutorial video on how to implement zoom traces on an HDO.

Back to Basics: Probes (Part II)

In a previous post, we provided some basic information about oscilloscope probes, including a brief survey of the different types and what can happen when the probe is connected to a DUT. In this installment, let's continue along those lines and take a closer look at passive probes.

To speak of an oscilloscope probe is to open a fairly large can of worms. There are many kinds of probes on the market, with differing functions and characteristics (Figure 1). This is the first in a short series of posts on the basics on probes, what the various kinds are used for, and how they might be expected to affect measurements taken with them.
