12 GHz Browser Head Combination for Oscilloscope Probes
16 March 2016 – Keysight Technologies introduced the N2839A differential browser head for use with InfiniiMax I/II Series probe amps, bringing the measurement fidelity of a solder-in probe head to hand-held browsing. When used with the InfiniiMax II 1169A probe amplifier, the N2839A gives users 12 GHz of bandwidth, making this a practical hand-held browser solution for measuring high-speed differential or single-ended signals.
Oscilloscope Probes with up to 20 GHz Bandwidth
15 March 2016 – Tektronix introduced the P7700 series of TriMode probes for use with Tektronix performance oscilloscopes. Offering up to 20 GHz bandwidth, the new probes ease the challenges designers face when debugging circuits found in the latest mobile and enterprise designs by minimizing probe loading, improving access to smaller, more-densely packed test locations and lowering overall cost of ownership.
Hybrid Memory Cube Compliance Test
08 March 2016 - Keysight Technologies introduced the industry’s first compliance test software application for hybrid memory cube (HMC) device and system testing. The Keysight N8839A HMC test application helps memory design engineers accelerate turn-on and debug of HMC systems by automating the execution of transmitter physical-layer tests on Keysight Infiniium V-Series and Z-Series oscilloscopes.

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.
