Oscilloscope Probing Solutions for High-Speed Bus Testing
03 March 2015 – Keysight Technologies introduced the bandwidth enhanced N7000A InfiniiMax III+ differential probes for general-purpose, high-speed differential bus probing. The company also introduced an active termination adapter that provides ultra-low noise voltage termination to a non-ground signal, and QuickTip accessories for InfiniiMax I/II probes. These probing solutions complement the new Infiniium V-Series oscilloscopes.
Oscilloscope Current Probe for up to 50 A and with 100 MHz Bandwidth
02 March 2015 -- Rohde & Schwarz enhances its oscilloscope accessories portfolio with the new R&S RT-ZC20B current probe. At 100 MHz bandwidth, the can measure AC and DC of a maximum 30 A (RMS)/50 A (peak) current with a resolution of 10 mA and low noise. R&S RTO, R&S RTE and R&S RTM oscilloscopes can automatically detect up to four current probes connected in parallel and will also automatically adjust the vertical scaling and zeroing settings. The degaussing function is activated directly on the instrument.
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.

Oscilloscope Probes – Vital Link in the Measurement Chain
Signal measurement results can only be as accurate as the test and measurement tools in use. As clock rates and edge speeds of today’s electronic circuits increase, probing becomes a critical piece of the measurement system – the component that comes in direct contact with your circuit. This article looks at voltage probing considerations for embedded system and digital design debugging applications.

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.
