Reducing ringing or reflections by controlling impedance lines
What is a controlled impedance line? For one thing, the term has to do with Printed Circuit Board (PCB) traces and layouts, which get more complex with higher frequency signals. Generally, you need not worry much about controlling impedance in traces unless you are working with signals at or above 50 MHz. However, most of […]
VIDEO: Basic Spectrum Measurements in the Tektronix RSA306B PC-Based Spectrum Analyzer
Bench-type spectrum analyzers are generally more costly than comparable oscilloscopes, but the Tektronix RSA306B makes use of the owner-supplied PC to reduce the cost substantially while maintaining a full range of features and specifications. Hi and welcome to our 88th Test and Measurement Video. For today’s demonstration, we’ll go back to the Tektronix RSA306B Real-Time […]
Software simplifies multi-Instrument setup, promotes fast data visualization
Keithley KickStart 2.0 software enables quick test set-up and data visualization when using single or multiple instruments. KickStart simplifies what users need to know about instruments so engineers can take instruments out of the box and quickly start gathering real data, complete with plots and quick statistical summaries. One of the most significant enhancements in […]
Understanding sampling modes in digital oscilloscopes
In a digital oscilloscope, the analog signal at the input, after attenuation/amplification and preliminary filtering such as for ac coupling, goes to an analog-to-digital converter (ADC). Each channel has a separate ADC, each with an external clock. Analog-to-digital conversion takes place by means of sampling. The samples are taken at specific rates and the amplitude […]
Working with bus analyzers
Protocol or bus analyzers (sometimes dubbed packet sniffers) are tools that intercept network traffic, store it, and then decode it for presentation in a human-readable state. Bus analyzers all have the same basic operating principle. They copy all network traffic out to a buffer or file. A lot of oscilloscopes include bus analyzer features. The […]
VIDEO: CAN Bus demonstrated in Tektronix MDO3104 Oscilloscope
The Tektronix Demo One board is used to access CAN Bus H and L differential signals. Hi again and welcome to our 87th Test and Measurement video. Today we’ll see how a Tektronix MDO3000 Series oscilloscope can display a CAN Bus serial signal. The source for the signal is a Tektronix Demo One board, which […]
