Test of Advanced Infotainment and Driver Assistance Systems
29 November 2021 - Keysight Technologies announced new automotive serializer/deserializer (SerDes) transmit and channel test applications, as well as an automotive adapter portfolio to verify mobile industry processor interface (MIPI) A-PHY and Automotive SerDes Alliance (ASA) standards. These solutions were developed in collaboration with Sony Semiconductor Solutions Corporation and Rosenberger.
5GHz Oscilloscope with Dual Screen
26 November 2021 - Rigol launched the dual screen DS70000 Ultra Vision III oscilloscope featuring 20 GSa/s based on a new capture chipset. The DS70000 Series is part of the StationMax program and uses the new Phoenix ASIC platform to achive higher sample rate, increased memory depth, faster waveform capture rate and better vertical resolution. The new Phoenix chipset was developed in-house and forms the analog front-end.
Long Time Data Acquisition with up to 20 MS/s
19 November 2021 - Yokogawa Test & Measurement added new features to its DL950 ScopeCorder. The latest Yokogawa ScopeCorder now offers flash acquisition as well as new real time computing functions, further improving data acquisition capabilities and adding firmware updatable features. Using the new Flash Acquisition function, data can be captured over a long time with a high-speed sample rate of 20 MS/s (8CH) and 10 MS/s (16CH), which is 100 times faster than the previous model.
I3C Serial Decoder for PicoScope Oscilloscopes
18 November 2021 - Pico Technology added another protocol to both PicoScope 6 (Stable) and PicoScope 7 (Early Access) implementations: MIPI I3C Basic specification waveforms can now be decoded, displayed and analyzed on any PicoScope with sufficient bandwidth and memory depth. I3C is a medium-speed control and data bus interface for connecting peripherals to an application processor in embedded systems and a range of mobile, Internet of Things (IoT) and automotive applications.
B&K Precision enhances Digital Storage and Mixed Signal Oscilloscopes
11 November 2021 - B&K Precision announced their latest iteration of performance oscilloscopes with the 2560B Series. This series improves on the previous 2560 series and introduces new features not typically found in other oscilloscopes in this class. Most noticeably, the increased maximum bandwidth to 350 MHz and the large 10.1-inch touchscreen display with intuitive touchscreen gestures.
Four new Protocol Decoders added
05 November 2021 - Pico Technology announced the inclusion of four new protocol decoders / analyzers with PicoScope software. MIL-STD-1553, CAN J1939, Quadrature encoded and Parallel bus decoders are included with the latest PicoScope 6 software (6.14.54) for Windows, Linux and macOS operating systems. The same decoders have also been added to PicoScope 7, the next-generation PicoScope user interface. (PicoScope 7 Early Access program gives users access to the software during the ongoing development work.)
Economy Oscilloscopes with 5 GSa/s analog Bandwidth
03 November 2021 - Teledyne expanded its Teledyne Test Tools with the new T3DSO3000 Oscilloscopes featuring four channel models with analog bandwidth options from 200 MHz to 1 GHz. Each model offers a maximum sample rate of 5 GSa/s, and a maximum memory depth of 250 Mpts in half channel mode. All models incorporate two 5 GSa/s ADCs and two 250 Mpts memory modules.

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.
