The table below allows you to easily determine the modulation level of an AM transmitter. Connect an RF sample to the horizontal input of an oscilloscope and set the peak-to-peak (pk-pk) unmodulated ...

Newman-Kees Principal Consulting Engineer Frank Hertel says a friend recently brought him an old LPB 30-Watt AM transmitter for repair. It’s a good low-power transmitter, but this one had been abused.

With the ever-expanding adoption of wireless in embedded systems of all types, there’s no question that having spectrum analyzer capability in an oscilloscope is a time-savings convenience for ...

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 ...

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 ...

Sometimes the old tricks are the best. [Kevin] learned an old trick about using a ‘scope to sniff RF noise and pays it forward by sharing it in a recent video. He uses an oscilloscope. But ...

a, Experimental setups for direct current (DC) and alternative current (AC) modulation characterizations, which consist of a light source, a metafiber EOM, a signal generator with a voltage amplifier ...

Rigol has added a vector signal analyser option to its RSA5000 series spectrum analysers, for characterising complex RF modulation schemes – including QAM, QPSK, ASK, MSK and FSK. “The VSA application ...
