40 Channels with up to 63 GHz Bandwidth
28 March 2014 – Agilent introduced its Infiniium Z-Series oscilloscopes, which can be synchronized to measure up to 40 channels simultaneously with a maximum 63-GHz real-time oscilloscope bandwidth (on up to 10 oscilloscopes). With industry-leading noise and jitter measurement floors, the new oscilloscopes enable engineers to effectively test devices that incorporate the newest technologies and achieve new performance milestones.
Next-Generation Oscilloscope User Interface
25 March 2014 – Agilent announced a next-generation user interface for its Infiniium real-time oscilloscopes. It is the first oscilloscope user interface to take advantage of new display technologies and significantly enhance the user experience by offering faster documentation, personalized viewing and improved usability.
Tektronix announces Pricing and Line-up Changes for Mixed Signal Oscilloscopes
04 March 2014 – Tektronix announced that its MDO4000B Series of Mixed Domain Oscilloscopes are now available at the same price point as MSO4000B Mixed Signal Oscilloscopes. The Tektronix Mixed Domain Oscilloscopes (MDO) include a built-in spectrum analyzer along with 4 analog channels and 16 digital signal inputs — with the MDO4000B Series enabling engineers to capture synchronized analog, digital and RF signals for a complete, time-correlated system view, saving debug time.
Rigol extends Mixed-Signal Digital Oscilloscope Family
03 March 2014 - RIGOL Technologies presents a mixed signal extension to the DS1000Z and DS2000A Digital Oscilloscopes series. The oscilloscopes offer a bandwidth from 70MHz to 300MHz and a specially designed analog front end with a lower noise floor and a wider vertical range (MSO2000A only 500 uV/div to 10 V/div) at full bandwidth. The instruments also leverage Rigol’s innovative "UltraVision" technologies from the DS6000 series.
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.

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.
