400G PHY Layer PAM4 Transmitter Validation
01 December 2016 - Tektronix released an update to its PAM4 solution for validating 400G physical layer transmitter designs for its DPO70000SX oscilloscope series. The latest release adds PAM4 error detection, industry-leading Signal to Noise and Distortion Ratio (SNDR) measurement capability, and new advanced FFE/DFE equalization capabilities into one easy to use solution.
Entry-level DSO featuring 7" Display and Standard LAN
29 November 2016 - B&K Precision replaced their former 2190D bench digital storage oscilloscope (DSO) with the model 2190E. Offering the same measurement capabilities of the previous 2190D, the 2190E continues to add more features to the entry-level 100 MHz DSO. New upgrades include a higher resolution display and standard LAN interface at no additional cost.
Teledyne LeCroy launches Active Voltage Rail Probe and SPMI Decoder
14 November 2016 – Teledyne LeCroy launched two new products – the RP4030 active voltage rail probe and an industry first MIPI System Power Management Interface (SPMI) serial decoder. The RP4030 probe measures small signal variations on a DC power/voltage rail, while the SPMI decoder monitors and correlates SPMI serial bus messages with DC power/voltage rail changes. These two products are ideal for testing line or battery-powered computing and embedded systems that use digital power management ICs (PMICs) to reduce power consumption and increase system efficiency.
Test Solution for ONFI Flash Memory Standard
07 November 2016 – Tektronix announced the industry’s first test solution for the Open NAND Flash Interface (ONFI) standard. Available for Tektronix high-performance oscilloscopes, the ONFI 4.0 test solution includes software for analyzing DDR2/3 modes on the ONFI bus coupled with an effective probing solution based on interposers.
Oscilloscope Probe for Voltages in the Millivolt Range
04 November 2016 - The new R&S RT-ZP1X passive 1:1 probe from Rohde & Schwarz f is ideal for measuring smallest signals down to 1 mV/div, e.g. for power integrity measurements on integrated circuits and components. The new passive 1:1 probe is precisely matched to the R&S RTE (up to 2 GHz) and the R&S RTO1000/2000 (up to 4 GHz) oscilloscopes.
DisplayPort Type-C Transmitter Test Solution
03 November 2016 – Tektronix announced a new DisplayPort Type-C Transmitter Test solution that significantly reduces compliance test times compared to both previous Tektronix DisplayPort solution and those available from competitors. According to real-world field evaluations, the highly optimized solution for use with Tektronix high-performance oscilloscopes allows engineers to complete the full suite of DisplayPort Type C compliance tests in less than 6 hours compared to competitive offerings that require up to 16 hours to complete -- a remarkable execution speed.
Debugging of complex 100G Datacenter Interconnects
01 November 2016 – Tektronix released a new 100G link training tool for use with its DPO70000SX family of ultra-high performance oscilloscopes. This new option, along with expanded measurement support for 100G electrical debug and validation, addresses critical needs in the growing datacenter market. The expanded analysis software for DPO70000SX series oscilloscopes helps engineers to debug complex high-speed Ethernet communications links.

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.
