PicoScope Oscilloscopes now run on Linux
28 February 2014 - Pico Technology has just released a beta version of the PicoScope 6 oscilloscope software for Linux. This is in response to requests from a large number of customers in the scientific and educational fields where Linux is widely used. PicoScope 6 is a powerful application that converts a PC into an oscilloscope, FFT spectrum analyser and measuring device. On-device buffering, using deep memory on some devices, ensures that the display is updated frequently and smoothly even on long timebases.
Rohde & Schwarz introduces new Oscilloscope Family
27 February 2014 - Rohde & Schwarz presented on the Embedded World trade fair in Germany the new R&S RTE oscilloscope family. The instruments are available with bandwidths from 200 MHz to 1 GHz, with an acquisition rate of more than one million waveforms per second and a highly accurate digital trigger system with virtually no trigger jitter. With a sampling rate of 5 Gsample per second and a maximum memory depth of 50 Msample per channel, the R&S RTE can accurately record the long signal sequences required when analyzing the data content of serial protocols such as I2C and CAN.
Tektronix integrates six Instruments in one Oscilloscope
26 February 2014 – The new MDO3000 Series of Mixed Domain Oscilloscopes of Tektronix includes a spectrum analyzer, logic analyzer, protocol analyzer, arbitrary function generator and digital voltmeter - all in one instrument. The MDO3000 clears the design bench of costly, specialized equipment and provides the tools needed to test and debug virtually any embedded design. In addition the MDO3000 is completely customizable enabling customers to select the functionality and performance needed now and later.
USB Oscilloscope with eight high-resolution Channels
25 February 2014 - The new 8-channel PC oscilloscope PicoScope 4824 from Pico Technology features eight high-resolution channels with 12-bit resolution, SuperSpeed USB 3.0 interface, and an integrated 14-bit arbitrary waveform generator (AWG). Like all PicoScopes, the 4824 is small, light, and highly portable; despite its high specification it is entirely powered via USB and does not require a bulky separate adaptor.
Faster, easier Debugging of DDR Devices
12 February 2014 – Agilent Technologies introduced a debugging tool that helps DDR memory designers perform precompliance tests, discover the root cause of compliance failures, and maximize design margins. The tool allows designers to easily navigate to areas of interest for further analysis and collect and analyze statistical data. The DDR3 and LPDDR3 debug tool runs on Infiniium 9000A, 90000A, 90000 X- and 90000 Q-Series oscilloscopes.
USB 3.0 SSIC and MIPI CSI-3 Protocol-Decoding Software for Oscilloscopes
30 January 2014 – Agilent Technologies introduced the industry’s first software for decoding USB 3.0 SuperSpeed Inter-Chip (SSIC) and MIPI Camera Serial Interface 3 (CSI-3) protocols on oscilloscopes. The new protocol decoders provide design and validation engineers with a fast, easy way to validate and debug their SSIC and CSI-3 interfaces.
Pico Technology joins the MathWorks Connections Program
17 January 2014 - Pico Technology announced that it has become a member of the MathWorks Connections Program. The PicoScope 3000 Series oscilloscopes now have an instrument driver for the Instrument Control Toolbox. This includes all models apart from the Mixed Signal and Differential Oscilloscopes, with drivers for other product ranges to be provided in the future.

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."

Precision Phase Noise Measurement with an Oscilloscope - Part 1
Often clock jitter induced from the power supply noise, signal routings, or other signals severely degrade the performance of the system. Clock generation and distribution in a FPGA for a high speed analog application is particularly prone to these issues. They manifest themselves in phase noise or clock jitter, which is the random variation of the period of a signal over time. Clearly, optimization of the design requires verification of the integrity of such clocks.
