I already asked about EMI data.
Is there a result of expanding the vertical range of 400 to 800 MHz in particular?
I want something that looks like a few dB levels.
unfortunately we do not save the data as you want. Is it frequency points or readings you want to see clearly?
Thank you for your reply.
I especially wanted to expand the 400MHz to 800MHz range.
I think that the way of peak standing is different depending on the input frequency, but I was wondering how many dBs of noise depending on the input waveform appear.
When one of our customers tested the noise test while communicating at 1 MHz, noise was observed from the harness outside the casing.
The problem was solved when replacing the mounted isolator with another's.
The other day I visited a customer and measured out of the casing, so now I doubt the conducted noise due to the difference in current consumption, not the radiated noise of a single device.
Therefore, we are asking the customer to test by increasing the capacity of the capacitor connected to the power supply.In addition, customers have a look at what happens when they stop communicating.
