More Memory for Yokogawa MSO Oscilloscopes
27 February 2015 - The new /M3 option of Yokogawa adds 250MPoints memory to DLM2000 and DLM4000 mixed-signal oscilloscopes. Larger memories offer two advantages - first more memory allows a longer acquisition time and second for the same acquisition time, using a larger memory can result in a higher sample rate - which actually means that the effective bandwidth of the measurement is increased.
Rohde & Schwarz expands its Family of R&S RTE Oscilloscopes
26 February 2015 -- Rohde & Schwarz introduced new two- and four-channel models with 1.5 GHz and 2 GHz bandwidth for its family of R&S RTE oscilloscopes. The bandwidth of this family is ranging now from 200 MHz to 2 GHz. The R&S RTE series features a 5 Gsample/s sampling rate per channel and up to 200 Msample memory. An extremely low-noise frontend, in conjunction with a sensitivity of up to 500 µV/div and a vertical resolution of 16 bit in high definition mode, ensures highly accurate measurement results. The digital trigger system operating in the signal path allows triggering in realtime on even the smallest signal details.
Keysight launches new 8 GHz to 33 GHz Oscilloscopes and high-speed Probing Solutions
24 February 2015 – Keysight Technologies introduced the Infiniium V-Series oscilloscopes featuring a low oscilloscope noise floor, low real-time oscilloscope jitter floor and high number of effective bits. The Infiniium V-Series provides superior measurement accuracy, enhanced analysis tools and advanced probing systems. With models ranging from 8 GHz to 33 GHz, the V-Series enables designers to make rapid progress from first silicon to crucial insights.
Motor Drive Analyzer based on high Resolution Oscilloscope
09 February 2015 - Teledyne LeCroy announces the MDA800 Series of Motor Drive Analyzers (MDAs) providing a complete three-phase power analysis from motor drive input through motor mechanical output. The Motor Drive Analyzers (MDAs) are based on the HDO8000 oscilloscope platform and are standard with 8 input channels (16 digital channels optional) with 12-bit resolution, 2.5 GS/s sample rate, up to 1 GHz bandwidth and up to 250 Mpts/ch acquisition memory.
Teledyne LeCroy enhances WaveSurfer 3000 Oscilloscopes with Multi-Instrument Capabilities
05 February 2015 - Teledyne LeCroy introduces additional multi-instrument capabilities for the WaveSurfer 3000 oscilloscopes. The new options include CAN and LIN trigger and decode capabilities for the protocol analyzer and additional arbitrary waveform generation capabilities for the WaveSource function generator. Also the new digital voltmeter (DVM) capabilities activate an integrated 4-digit digital voltmeter and 5-digit frequency counter that operate through the same probes already attached to the oscilloscope channels.
Power Analyzer with Oscilloscope Visualization Capability
02 February 2015 - Keysight Technologies introduced a power analyzer that combines accurate power measurements and touch-driven oscilloscope visualization capability in a single instrument. The Keysight IntegraVision power analyzer features 2 isolated channels for up to 1,000 Vrms and 2-Arms and 50-Arms direct current input – all with 0.05 percent basic accuracy and 16-bit resolution. The power analyzer enables engineers to characterize power consumption under highly dynamic conditions with 5-M samples per second digitizing speed and 2-MHz bandwidth.
A Comparison between Oscilloscopes and Spectrum Analyzers
Whether it is for a land survey searching for minerals on Earth, or for a space exploration in search of alien life forms, the analysis of any signal boils down to looking at its time and frequency information. While an oscilloscope displays a signal with respect to time, a spectrum analyzer shows it with respect to frequency. Both of these tools are very important in any signal analysis application. This article explains the difference between oscilloscope and spectrum analyzer using examples.

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."

Oscilloscope History and Milestones
Oscilloscopes have been invented in the 1920s. Up to now this instrument encountered many innovations. In the beginning the most important manufacturers have been General Radio, DuMont, General Electric and Radio Corporation of America. Later Cossor and later Solartron dominated the market. Today the main players are Keysight, Tektronix and Teledyne LeCroy. Below we listed some important oscilloscope milestones.
