In measuring or displaying weak signals, noise places the ultimate limit on detectability. It usually appears as a fluctuating horizontal line known as the noise floor in a spectrum analyzer of oscilloscope in FFT or RF mode. In the time domain, it appears as a thickening of the trace and in severe instances, causes a […]
Ethernet switch passes 1000BASE-T1 compliance tests for automotive apps
Rohde & Schwarz and Marvell were the first companies to successfully execute 1000BASE-T1 compliance tests, for the Marvell’s 88Q2112 Ethernet transceiver, using an R&S RTO oscilloscope. The latest improvements to the R&S RTP oscilloscope family include the 16-GHz acquisition bandwidth required to perform signal integrity tests and debugging for SerDes, LVDS, PCIe Gen 3.0, MIPI […]
How to measure CCD and CMOS image sensor qualities
Today, about 95% of all digital cameras use CMOS image sensors with the rest employing CCDs. From the standpoint of sensor outputs, the main difference between CMOS and CCD sensors is that each pixel in a CMOS sensor has its own readout circuit next to the photosensitive area. In CCDs, charge collected in individual pixels […]
Hand-held spectrum analyzer app streamlines in-building signal mapping
A hand-held spectrum analyzer series (Spectrum Compact) coupled with NEON Signal Mapper software delivers real-time geo-referenced signal data that can be visualized both locally by the user and remotely on a 3D display. This new in-building signal testing solution leverages the Spectrum Compact’s exceptional measurement accuracy and industry-leading noise floor (-128 dB) to provide a […]
More MDO3000 Series scope menus and front panel controls
A previous article covered many of the Tektronix MDO3000 Series Oscilloscope menus and front panel controls. Now we bring the survey closer to completion. Rather than memorizing all the details, you can refer to the user manual, connect to the internal or external AFG for sample waveforms, and start pushing buttons. Don’t worry, the oscilloscope […]
PCI Express test gear supports PCIe 5.0 base spec Rx tests
A new PCI Express test solution supports the Gen5 Base Specification Stressed Receiver Test. The test setup features the Signal Quality Analyzer-R MP1900A Series with installed Automation Software for base specification calibration and BER Measurement Software supporting the SKP Filter. With the release of this system, engineers can easily configure a measurement environment for early-stage […]
Displaying waveforms and trace data in the Tektronix MDO3000 Series oscilloscope
When you are trying to get an accurate idea of waveform qualities from a scope display, the display settings are quite important. So it can be helpful to review the setup process in widely used scopes such as a Tektronix MDO3000. Display style and persistence in this instrument can be accessed by pressing the Acquire […]
Basic and advanced modes in the Tektronix AFG31000 Series arbitrary function generator
Early signal generators, dependent upon vacuum-tube technology and subject to failure, were ancestors of today’s far more precise and durable arbitrary function generators. These instruments have advanced modes and functions that figure prominently in research and product development as well as troubleshooting and repair. Here the word “arbitrary” means the instrument is capable of generating […]
