Yokogawa enhances Mixed Signal Oscilloscopes
01 August 2014 - Yokogawa enhanced its DLM2000 mixed-signal oscilloscope with longer memory capabilities and a number of firmware improvements. In the new version, the length of the acquisition memory has been increased up to 62.5 Mpoints in the standard unit and up to 250 Mpoints with the extended memory option. This means that, with the maximum memory installed (/M3 option), in single-shot mode, a 10 kHz signal lasting for more than one hour can be captured.
BroadR-Reach Interface Verification with Oscilloscopes
29 July 2014 — Rohde & Schwarz has expanded the application field of the R&S RTO oscilloscopes to include the testing of automotive Ethernet interfaces. In line with the OPEN Alliance test specification, the new R&S RTO-K24 compliance test software enables users to perform automated tests on BroadR Reach Ethernet interfaces. BroadR Reach technology makes it possible to combine multiple applications such as video streaming from rear view cameras and signal transmission from automotive radar systems to create a single, open and scalable Ethernet network inside the vehicle.
High Voltage Differential Probes for Oscilloscopes
17 July 2014 - Teledyne LeCroy introduced the HVD High Voltage Differential probe series delivering high common-mode rejection ratio (CMRR) across a broad frequency range. The new HVD differential probes are safe, easy to use and ideally suited for a variety of power electronics measurements. The wide 1500Vp-p differential voltage range and large offset capability provides maximum flexibility for capturing gate drive and control signals floating on a 1000 Vdc bus. This performance combined with 1% DC and low frequency gain accuracy means the HVD differential probes enable high precision, high voltage measurements.
Five essential Instruments in a single Device
15 July 2014 – National Instruments (NI) announced VirtualBench, an all-in-one instrument that integrates a mixed-signal oscilloscope, function generator, digital multimeter, programmable DC power supply and digital I/O. Users interact with VirtualBench through software applications that run on PCs or iPads. The device provides the most common functionality affordably and opens up new possibilities for how engineers can use benchtop instruments.
Oscilloscopes with Bandwith up to 500 MHz and large 10.1" Touch-Screen Display
07 July 2014 - Teledyne LeCroy introduced the WaveSurfer 3000 series of oscilloscopes featuring the MAUI advanced user interface. This advanced user interface, previously available only on higher-end oscilloscopes, seamlessly integrates a deep measurement toolset and multi-instrument capabilities into a cutting edge user experience centered on a large 10.1" touch screen, the largest display and only touch screen in this class of oscilloscope. WaveSurfer 3000 oscilloscopes are available in bandwidths from 200 MHz to 500 MHz, with 10 Mpts/ch memory and up to 4 GS/s sample rate.
12-Bit Oscilloscope with 8 Channels and 1 GHz Bandwidth
25 June 2014 - Teledyne LeCroy announced the HDO8000 oscilloscope product line with 8 analog input channels, 12-bits of vertical resolution utilizing Teledyne LeCroy's HD4096 technology, and up to 1 GHz of bandwidth. The HDO8000 oscilloscopes have maximum performance, going further (8 channels), with finer resolution (12-bits) and faster (up to 1 GHz bandwidth). A wide variety of mixed-signal, serial data, long memory, and probe options and accessories are available with the HDO8000 oscilloscopes.
500 MHz portable Oscilloscope with 4 Channels
24 June 2014 — Fluke introduced the Fluke 190-504 Series II 500 MHz ScopeMeter Portable Oscilloscope. The instrument achieves a 500 MHz at 5 GS/s real time sample rate in a 4-channel handheld, sealed, and rugged oscilloscope without compromising on safety rating, ruggedness, or battery operating time. The Fluke 190-504 fills the needs of professional electronic troubleshooters who need the fast 5 GS/s — or 200 pico seconds — sample rate and 4-channels for greater accuracy and clarity of shape and amplitude of unknown waveform phenomena like transients, induced noise and ringing or reflections.

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.
