HDMI 2.0 Compliance Test Software for Transmitters and Receivers
16 January 2014 – Agilent Technologies introduced two compliance test software packages for physical-layer testing of devices that use the new High-Definition Multimedia Interface (HDMI) 2.0 specification. The transmitter compliance test software allows engineers to use Agilent Infiniium oscilloscopes to test their HDMI 2.0 transmitters. Agilent’s receiver compliance software can be used with the company’s transition-minimized differential-signaling signal generator platform and the Agilent M8190A arbitrary waveform generator to test HDMI 2.0 receivers.
World’s first Combination of Power-Analyser and Oscilloscope
16 January 2014 - Yokogawa has combined its world-leading expertise in power measurement and its long heritage in oscilloscope design to create the world’s first Precision Power Scope: the PX8000.The PX8000 brings oscilloscope-style time-based measurement to the world of power measurement. It can capture voltage and current waveforms precisely, opening up applications and solutions for a huge variety of emerging power measurement problems.
Handheld Digital Storage Oscilloscopes for Industrial Applications
14 January 2014 - B&K Precision announced its new 2510 Series handheld digital storage oscilloscopes (DSO). Four models make up this new line of dual-channel oscilloscopes that includes 60 MHz and 100 MHz bandwidth models in non-isolated and isolated designs. Suitable for general electronics, models 2511 and 2512 provide non-isolated 300 V CAT II rated inputs. For industrial applications, models 2515 and 2516 provide two fully isolated 1,000 V CAT II / 600 V CAT III rated inputs.
Digital Debugging - better using a Mixed-Signal-Oscilloscope or a Logic Analyzer?
Today’s technology is fundamentally balanced on an increasingly fine line between the analogue and digital domains; as data speeds increase — both within and between devices — the ‘ideal world’ of fast, clean digital transitions becomes evermore difficult to achieve. This presents new and escalating challenges when verifying faster digital signals that exhibit more and more analogue-like features. As a result it is becoming necessary to remove the hard line between digital and analogue.
A simple method to verify the bandwidth of your probe
In oscilloscopes or oscilloscope probes, bandwidth is a measure of the width of a range of frequencies measured in Hertz. Specifically, bandwidth is specified as the frequency at which a sinusoidal input signal is attenuated to 70.7 percent of its original amplitude, also known as the -3 dB point. Most oscilloscope companies design the scope/probe response to be as flat as possible throughout its specified frequency range, and most customers simply rely on the specified bandwidth of the oscilloscope or oscilloscope probes, wondering if they are indeed getting the bandwidth performance at the probe tip. Now you can use these step-by-step instructions to simply measure and verify the bandwidth of your probe with an oscilloscope you may already have.
Oscilloscope Probes – Vital Link in the Measurement Chain
Signal measurement results can only be as accurate as the test and measurement tools in use. As clock rates and edge speeds of today’s electronic circuits increase, probing becomes a critical piece of the measurement system – the component that comes in direct contact with your circuit. This article looks at voltage probing considerations for embedded system and digital design debugging applications.

Digitizer and Oscilloscope - Equal Alternatives?
Can a digitizer be used as an oscilloscope? What is the difference between an oscilloscope and a digitizer? Should I better use a digitizer or an oscilloscope in my next application? These are interesting questions and the best way to start to answer these is the look up the dictionary definition of an oscilloscope: "An electronic instrument used to measure changing electric voltages. It displays the waveforms of electric oscillations on a screen."
