Two Gigabit LTE software options for the Anritsu Signalling Tester MD8430A support the increased communications speeds associated with LTE-Advanced Pro (LTE-A Pro). The LTE DL 6 Carrier Aggregation Option and LTE UL 256QAM Option extend the measurement capability of the MD8430A and provide engineers with a comprehensive test solution to accurately and efficiently evaluate LTE-A […]
Test and Measurement Tips
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 […]
Measuring polarization
Any treatment of wave polarization must begin with a discussion of the differences between transverse and longitudinal waves. That is because polarization either as a process or a state applies only to transverse waves, not to longitudinal waves. Longitudinal waves are those in which the oscillations are in the direction of propagation. Examples of longitudinal […]
Lock-in amps get AM/FM modulation option
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.

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, […]
