The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

There was a time when every broadcast engineer had an oscilloscope for troubleshooting and aligning equipment, from a microphone input to the antenna. It is true that the nature of our plug-and-play ...

Oscilloscopes remain a hot topic on the RF DesignLine, so I had a virtual “sit down” with some leaders in the industry to see where the technology is, and where they think it is going. The following ...

In the process of debugging and validating both digital and RF designs, the oscilloscope Fast Fourier Transform (FFT) function and a variety of other math functions can prove valuable to designers ...

Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...

Tektronix has released its SignalVu Spectrum Analyzer Software, Version 5.4, for multi-channel modulation analysis of up to eight signals in parallel. Engineers can use this software to turn their ...

When you perform EMC tests, you often think of emissions measurements made with a spectrum analyzer. But, there are EMC applications for oscilloscopes. A relatively underutilized use for oscilloscopes ...

Rohde & Schwarz is claiming to have invented a new test set-up for verifying power amplifier performance when connected to an antenna, which typically shows a dispersive impedance, by swapping the ...
