l Automatic Fixture Removal
The 6433 series Lightwave component analyzer can automatically remove the fixtures connected to the test link through optical de-embedding and radio-frequency de-embedding. When electrical fixtures or optical fixtures are introduced into the test link, users can select the enable state of radio frequency de-embedding and optical path de-embedding, import fixture parameter files, and automatically remove fixture data to improve measurement accuracy. Especially when the probe error required for the chip test is removed, the measurement is more flexible and meets the measurement needs of users in different occasions.
