During EMC test, it was found that re could not reach the switching frequency of 400kHz power amplifier required by the customer.
Is there any suggestion that we conduct more tests, attached with the experiments we have done so far.
Customer requirements are as follows:
Our test results are as follows:
Circuit diagram：
Experimental records：
PI filter is added at the power input, as follows:
At present, according to the test, 400kHz is radiated through the horn wire. Changing the external horn wire to shielded wire will improve, but it still can not meet the customer's requirements
Conducted radiation can meet the requirements
At present, the antenna radiation can not meet the requirements. Are there any suggestions to solve it
