Generation of different signals simultaneously with APx585

Since WAV files can be used to transmit them through generator outputs, it is possible to transmit different signals simultaneously by assigning each of the output channels the relevant signal. WAV files can be generated with an audio editor, with some Matlab-type development environment or through the applicationAPx Waveform Generatorattached to this article. This application has an option to create a WAV file with different channels (up to 16 channels), each containing shades of different frequency (the generated file will have such a name such that "Channel_ID_MultiChannel_48k.24_8.wav").

Once the WAV is created with the different signals, we will load it into the measurement to be performed (Level and Gain in this example):

And we will assign each signal to each output channel by selectingCustominChannel assigments:
