Hi Team,
The customer is using LM1971. LM1971 can be attenuation step size from 0dB to -62dB. But when the customer sets LM1971 to be attenuation 0dB,
the output signal is more attenuation than the input signal. Look the attachment. The channel 1 is the the input signal and the channel 2 is the output signal.
What is the reason? How to solve the issue?
Thanks,
Best Regards,
