4 Channel 20 GHz Sampling Oscilloscope
22 October 2014 - With the new PicoScope 9341 20 GHz Sampling Oscilloscope, engineers can analyze two differential or four single-ended high-speed signals. The instrument is ideal for measuring skew and crosstalk between differential pairs on serial buses such as HDMI, SATA and PCIe, and for testing signal integrity at differential and single-ended transceiver ports. Data rates up to 40 Gb/s can be viewed, with 5th-harmonic characterization possible up to 8 Gb/s.
USB-connected Mixed-Signal Oscilloscopes
15 October 2014 - The new PicoScope 3000D Series Mixed-Signal Oscilloscopes (MSOs) form a complete portable test system, with two or four analog channels and sixteen digital channels as well as a built-in arbitrary waveform generator. The PicoScope 3000D Series MSOs are available with analog bandwidths from 60 MHz to 200 MHz. Maximum digital input frequency is 100 MHz, equivalent to a data rate of 200 Mb/s (5 ns pulse width) on each channel.
Teledyne LeCroy introduced new 1 GHz, 10 GS/s Oscilloscope
14 October 2014 - Teledyne LeCroy introduced the WaveSurfer 10 oscilloscope with 1 GHz and 10 GS/s at €9,990/£8,640. The WaveSurfer 10 combines the MAUI advanced user interface with powerful waveform processing, in addition to advanced math, measurement and debug tools, to quickly analyze and find the root cause of problems.
Testing USB Interfaces with an Oscilloscope
10 October 2014 - Developing USB-capable devices and integrating their interfaces requires reliable, fast and easy-to-operate test solutions. The R&S RTO-K60 triggering and decoding option addresses this need for USB 1.0/1.1 and 2.0 as well as for the high-speed interchip (HSIC) version. This option together with the R&S RTO-K21 compliance test software and the R&S RTO-ZF1 test fixture set from Rohde & Schwarz is the ideal tool for developers who have to integrate USB interfaces.
Entry-level Mixed Signal Oscilloscope with 1 GSa/s
07 October 2014 - Fanless operation, 1MPts of memory depth and a 1 GSa/s realtime sampling rate - these are the key features of the new R&S HMO1002 mixed signal oscilloscope from Rohde & Schwarz. With a vertical sensitivity of 1 mV/div and integrated 128 Kpoint FFT, the instrument offers features that are exceptional in the three-figure price segment.
Motor Drive Power Analyzer Software for Oscilloscopes
06 October 2014 - Teledyne LeCroy announces three-phase Motor Drive Power Analyzer software for its HDO8000 oscilloscopes. The HDO8000 mixed-signal oscilloscopes, with 8 input channels, 12-bit resolution, and up to 1 GHz bandwidth, are the perfect solution for motor drive embedded control and power section debug. With the addition of three-phase power analyzer capability and motor speed and torque integration, the complete drive system can be more quickly and easily validated and debugged, and extensive drive and motor power and efficiency measurements may be performed.
Teledyne LeCroy introduces 500 MHz Touch Portable Oscilloscope
29 September 2014 - Teledyne LeCroy introduced the WaveJet Touch oscilloscope, providing an unprecedented combination of performance and price - 500 MHz for $5,000. Built on the popular WaveJet 300 oscilloscope platform, the WaveJet Touch is available in two models with 350 MHz or 500 MHz bandwidth, four channels, up to 5 Mpts of memory at 2 GS/s, and a 7.5" touch screen display.

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."

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.
