Comprehensive 10BASE-T/100BASE-TX Ethernet Protocol Decoders
20 April 2015 – Keysight Technologies introduced comprehensive 10BASE-T/100BASE-TX Ethernet protocol decoders. The Keysight N8825A (for 90000A, 90000 X-, 90000 Q-, Z- and V-Series oscilloscopes) and N8825B (for S-Series oscilloscopes) 10BASE-T/100BASE-TX Ethernet protocol decoders help network design engineers accelerate turn-on and debug of 10BASE-T/100BASE-TX Ethernet networking systems by decoding 10BASE-T and 100BASE-TX Ethernet packets on compatible oscilloscopes with a minimum of 500-MHz bandwidth.
New In-Vehicle Serial Bus Options for Yokogawa Mixed-Signal Oscilloscopes
17 April 2015 - Yokogawa offers new trigger and analysis options for its DLM2000 (4-channel) and DLM4000 (8-channel) mixed-signal oscilloscopes (MSOs) for testing the latest generation of in-vehicle serial buses. The new options are specifically designed to address the measurement challenges posed by the CAN FD (CAN with Flexible Data Rate) and SENT (Single Edge Nibble Transmission) bus systems.
Teledyne LeCroy introduces High Sensitivity Current Probes
15 April 2015 – Teledyne LeCroy introduced the CP030A and CP031A high sensitivity current probes featuring a sensitivity down to 1 mA/div allowing users to measure current from the mA range up to a continuous current of 30Arms and peak current of 50A all with the same probe. The probes provide a small form factor for today’s crowded boards. The small jaws can probe currents in tight spaces and still clamp onto conductors up to 5 mm in diameter. The CP030A and CP031A feature a bandwidth of 50 MHz and 100 MHz, respectively.
In-line BNC adapter for BitScope Micro Oscilloscopes
14 April 2015 - The new BitScope Micro Port 02 (MP02A) is an in-line mixed signal I/O adapter for BitScope Micro. It can be used to connect standard oscilloscope probes and BNC terminated cables to BitScope Micro. Any oscilloscope probe with 1:1, 10:1 or other attenuation ratio can be used. It supports active differential, current or any other probe which is BNC terminated and designed for an oscilloscope.
Teledyne LeCroy announced PAM4 Signal Analysis Software
13 April 2015 – Teledyne LeCroy launched a PAM4 Signal Analysis software for its real-time oscilloscopes. This new set of analysis tools makes essential eye, jitter and noise measurements on all three eye openings of a PAM4 signal, a requirement for engineers who are designing next-generation electrical and optical links that seek to double data transfer rates by leveraging PAM4 signaling.
Teledyne LeCroy introduces new LabMaster and WaveMaster Oscilloscopes
10 April 2015 – Teledyne LeCroy enhanced its two highest performance oscilloscope product lines. The new LabMaster 10 Zi-A delivers improved performance in effective number of bits and baseline noise along with the industry leading jitter measurement floor. The new WaveMaster 8 Zi-B features increased sample rate, lower noise, enhanced processing capabilities and the latest version of Teledyne LeCroy's advanced oscilloscope user interface, MAUI.
Coupling up to 10 Oscilloscopes with up to 40 Channels
09 April 2015 - Keysight introduced the N8834A MultiScope software to connect up to 10 of Infiniium Series oscilloscopes to achieve 40-channel acquisition. The software provides a tight time correlation between the multiple scopes and is able to achieve inter-scope intrinsic jitter of 150 fs with precision calibration (90000 Q- and Z-Series only). The software allows users to perform multi-lane oscilloscope analysis for applications such as optical networking, MIMO, DDR memory and high-speed serial standards.

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.

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.
