Lock-in amplifiers can be equipped with amplitude and frequency modulation capabilities with the new AM/FM Modulation Option. This option enables coherent generation and detection of signals with multiple frequency components, such as amplitude- and frequency modulated signals. Up to three frequencies can be coherently combined to generate fully configurable AM signals. The three characteristic frequency […]
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 […]
Saelig to stock Teledyne LeCroy HVD3000A Series 1-6kV high-voltage differential probes
The Teledyne LeCroy HVD3000A High-voltage Differential Probes – the 1kV HVD310xA, the 2kV HVD3206A, and the 6kV HVD3605A — are now stocked by Saelig Co. Inc. These probes provide excellent CMRR over a broad frequency range to simplify the measurement challenges found in noisy, high common-mode power electronics environments. The probe’s design makes it easy […]

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 […]
Economical scopes get wider bandwidth, new functions for power electronics testing
WaveSurfer 3000z oscilloscopes expand the WaveSurfer 3000 bandwidth range above and below that of earlier models, while also adding new functions for power-electronics testing. In addition, the new models provide more processing power and memory. All WaveSurfer 3000z oscilloscopes feature a large 10.1-in. capacitive touchscreen, a vast set of debug and analysis tools, multi-instrument capabilities, […]
The basics of bus analyzers
Like a logic analyzer, a bus analyzer is capable of monitoring and capturing bus communication data. Both instruments decode, analyze and display that information. There are, however, significant differences. While a logic analyzer can display data from any of a large number of buses, an individual bus analyzer is built to work with only a […]
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 […]
