Signal Analysis with Oscilloscopes
Oscilloscopes offer numerous possibilities for signal analysis. Some functions are standard and included in nearly every oscilloscope (e.g. time measurements, frequency, rise/fall times,...) others need to be included often as options (e.g. FFT, spectrum analysis, eye diagram,...). Following a list of all news related to signal analysis with oscilloscopes:
5G Analysis Software for Oscilloscopes
01 March 2022 – Tektronix announced the release of its SignalVu 5G NR analysis software for 6 Series B MSO oscilloscopes. Engineers can now perform critical 5G NR measurements per 3GPP specifications on the oscilloscopes they rely on to bring-up and characterize new electronic designs. The 5G software enables engineers to diagnose complex signal interactions on a single oscilloscope, reducing the need for painstaking correlation between instruments.
New Approach for Signal Integrity Debugging
27 January 2020 - A new approach helps development engineers gain more insight into the individual jitter components of their transmission interface. Now they can separate jitter into its random and deterministic components and view results flexibly for effective debugging. The Rohde & Schwarz decomposition algorithm uses a parametric signal model for accurate measurements and additional result representations.
PAM4 Optical Signal Analysis up to 53 Gbaud
10 September 2018 – Anritsu introduced a new firmware for the BERTWave MP2110A Sampling Oscilloscope. The new firmware will increase its PAM4 analysis function from 26 Gbaud to 53 Gbaud targeting production and inspection of optical modules. As well as featuring both high-sensitivity and high-speed measurements, with this release the MP2110A will now support development and production-line inspection of next-generation QSFP-DD optical transceivers expected to be deployed in data centers.
Simple Analysis of Thousands of Waveform Cycles
17 August 2017 - Pico Technology introduced the DeepMeasure analysis tool. Included as standard with PicoScope 3000, 4000, 5000, and 6000 Series oscilloscopes, DeepMeasure delivers automatic measurement of waveform parameters on up to a million successive waveform cycles. Results can be easily sorted, analyzed and correlated with the waveform display.
Signal Analysis Reference Solution for Millimeter Wave Test
23 May 2016 - Keysight Technologies, announced an E-band Signal Analysis Reference Solution to provide low-cost millimeter wave analysis capability for applications in the 60-90 GHz range. The reference solution is based around the 10-bit ADC Infiniium S-Series oscilloscope to provide 2.5 GHz of high-fidelity, millimeter wave frequency analysis bandwidth.
Crosstalk Analysis with Real-Time Oscilloscopes
28 January 2016 - Keysight Technologies announced the comprehensive N8833A and N8833B crosstalk analysis application to assist in the diagnosis of crosstalk. The application not only detects and quantifies the presence of crosstalk, but it can determine which aggressors are primarily responsible. Furthermore, the application can go one step further by actually removing the crosstalk from the victim waveform so engineers can visually compare the original waveform with the clean waveform side-by-side.
Precision Phase Noise Measurement Technique - Part 2
In the first part of this article a simple phase noise measurement technique with a resolution of 10 ps was explained. There are other techniques, which could enhance the performance of the measurement to sub-picoseconds. That is the subject of this article.
Flexible Vector Signal Analysis for Oscilloscopes
08 January 2016 – Teledyne LeCroy introduced the VectorLinQ vector signal analysis software option for its oscilloscope products. VectorLinQ enables sophisticated visualization and analysis of standard modulation schemes including n-PSK, n-QAM, circular QAM, ASK, and FSK, as well as custom signal types and symbol positions. The VectorLinQ software includes functionality to either demodulate RF signals for analysis, or directly acquire and analyze baseband I and Q signals.
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.
Tektronix offers PAM4 Analysis Solution for Real Time and Equivalent Time Oscilloscopes
05 October 2015 - Tektronix announced that its comprehensive set of analysis tools for emerging PAM4 modulation now operates on both DPO70000SX 70 GHz real time and DSA8300 equivalent time oscilloscopes. PAM4 is being adopted in the latest 400 Gigabit Ethernet standard by the IEEE P802.3bs working group for 400G (typically 8 x 50G) electrical and optical interfaces. Compared to traditional NRZ that uses two-level signaling, the four-level scheme used in PAM4 significantly increases signal complexity and places new demands on test equipment for performance and noise sensitivity.
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.
Pulse Amplitude Modulation (PAM-4) Analysis with Oscilloscopes
28 January 2015 – Keysight Technologies introduced the Keysight 86100D-9FP PAM-N analysis software. It is designed to help engineers quickly and accurately characterize PAM-4 (pulse amplitude modulation with four amplitude levels) signals using the Keysight 86100D DCA-X wide-bandwidth oscilloscope platform. The software supports a comprehensive analysis of optical and electrical PAM-4 signals.
