EM TEST
5.10.2. Voltage attenuation at sine ripple frequencies
Using an individual amplitude control with sine ripple, the user must compensate the attenuation of the amplifier
frequency bandwidth. The table below shows the attenuator factor for frequencies range 1kHz to 100kHz.
The ripple voltage must respect the voltage limitation (see chapter 4.7)
