Keysight Technologies Two-Way Radio Testing with the U8903A Audio Analyzer Application Note Introduction As the two-way radio band gets deregulated, there is a noticeable increase in product offerings in this area. What was a specialized field with a product premium many years ago has turned competitive. In some instance, some product offerings in this area has become a commodity. This application note highlights how you can use the Keysight Technologies, Inc. U8903A audio analyzer to guarantee the audio quality of your design for you to use audio as a competitive advantage. 03 | Keysight | Two Way Radio Testing with Keysight U8903A Audio Analyzer - Application Note Combining the U8903A Audio Analyzer with the Keysight N9063A MXA Spectrum Analyzer and E4428C Signal Generator Provides a Good Solution for Two-Way Radio Testing + + A two-way radio transfers a signal (audio source) to another two-way radio by using frequency modulation (FM) radio frequency (RF) wave. During this process, the two-way radio converts the audio source to frequency modulated RF waves and sends it to a receiver. Then, the receiver demodulates the FM RF wave back to the original audio signal generated by the source. There are two major tests for a two-way radio: Transmitter and receiver tests. In a two-way radio transmitter test, the audio analyzer provides a 1 kHz audio tone signal to the two-way radio transmitter (DUT). The transmitter (DUT) converts the signal to FM RF waves, which will be measured using the N9063A MXA spectrum analyzer. During the two-way radio receiver test, the audio analyzer provides a 1 kHz audio tone signal to the signal generator. The signal generator converts the 1 kHz audio tone signal to frequency modulated RF waves and transmits the FM RF waves to the two-way radio receiver (DUT) for demodulating back to an audio sou
