Audio Amplifier Frequency Response
This application note shows how to measure the frequency dependent characteristics of audio amplifiers.
The Bode 100 can be easily used to measure the 3 dB bandwidth or the influences of different settings of the sound system's equalizer. The output and input impedances of the sound system can also be measured easily. To learn how to use the Bode 100 to measure different characteristics of audio amplifiers please download this application note:

Loudspeaker and Audio Crossover Measurements
This application note shows how to measure the impedance of loudspeakers as well as how to measure the voltage transfer function of audio crossovers.
With the Bode Analyzer Suite, it is very easy to visualize the measurements of both paths of the frequency crossover as well as to export the measurement to a csv document. In the application note, it is also showed how to measure the impedance of the loudspeakers and it can be seen how nonlinear the impedance of the loudspeakers are.
