A few decades ago, virtually all computer monitors, radar installations, TVs and oscilloscopes employed cathode ray tubes for the user’s visual interface. Today, except for a few educational models and replacements for radar installations, CRTs aren’t used as displays. (CRT material and process technologies are still common in the vacuum tube industry as a whole […]
Cathode ray tube testing using an oscilloscope
The cathode ray tube (CRT) is what made possible TVs, computer monitors, and oscilloscopes as we know them. CRTs have largely been replaced by flat-screen technologies but CRTs still serve in niche applications. For example, some kinds of military needs still require a CRT display. General-purpose CRTs are no longer manufactured in the U.S., but […]
How to select an oscilloscope
by David Herres, Contributing Editor Here’s a quick review of what’s important to know about the wide assortment of scopes and scope features available today. Other than the multimeter, by far the most useful test equipment in an electronics lab or maintenance shop is the oscilloscope. In recent years, this instrument has evolved in unexpected […]
H-P, Agilent, Keysight: New name, same reputation
Those of us who have been around electronic instrumentation for a while can remember the days when Hewlett-Packard instruments were considered the cream of the crop. Where I worked, we always tried to get to the lab early on the days we had tests to run so we could get our hands on the highly […]
Video: Tektronix MSO2024 Oscilloscope Product Review
For the sake of this demonstration, I will be looking at the frequency anomalies, using a DPO circuit board and MSO2024 Oscilloscope courtesy of Tektronix. Previously, I wrote a blog on Frequent engineers/designers mistakes specifying power products on the powersupplytips.com site. In this blog, there are questions to what designers should pay attention to. Designers […]
Agilent Technologies and SiSoft Introduce Pre-Standard IBIS-AMI Modeling Guide
Agilent Technologies Inc. and Signal Integrity Software, Inc. announced guidelines that enable system designers to use advanced jitter and broadband analog capabilities when modeling high-speed serial devices. The modeling guidelines are based on proposed enhancements to the IBIS Algorithmic Modeling Interface (116-118 and 123.5), which are expected to be included in the specification’s next version. Both SiSoft […]
Tektronix Introduces the 30 GHz Probing System
Tektronix, Inc. announced the 30 GHz probing system with coaxial connectors. The new P7600 Series Probing System features probe-specific DSP filters that enhance performance and minimize noise levels. When paired with the Tektronix DPO/DSA73304D oscilloscope, the P7600 Series Probing System provides connectivity and signal fidelity for high-speed differential signal measurements on serial bus designs like PCI Express. […]
Digitizing Oscilloscopes
One of the important signal integrity measurement solutions is the digitizing oscilloscope. Digitizing oscilloscopes have different forms — the sampling oscilloscope, the digital phosphor oscilloscope (DPO) and the digital storage oscilloscope (DSO). Ideally suited for low-repetition signals with narrow pulse widths or fast edges, the DSO can easily capture transients and one-time events, and is […]
Different types of oscilloscopes
Analog oscilloscopes, which employ cathoderay tubes to display a waveform, were the first oscilloscopes that were used by engineers. The screen’s photoluminescent phosphor illuminates every time an electron hits it. A representation of signal is displayed as successive bits of phosphor light up, while a trigger makes the displayed waveform appear stable. Upon completing an […]
Agilent introduces world’s fastest real-time oscilloscope
Agilent Technologies (www.agilent.com) is proud to launch its DSOX93204A high-performance oscilloscope – industry’s best 32GHz true analog bandwidth with 80GSa/s sample rate for two channels and 40GSa/s sample rate for four channels. The oscilloscope has the highest real-time scope measurement accuracy – the highest true analog bandwidth in the market (twice the analog bandwidth than […]
