Zero set performance verification
This performance verification is carried out to verify that a minimal amount of
residual offset error is present after zeroing has been performed. The offset error is
caused by contamination from several sources including the noise of the DUT
itself. Zero set is the difference between the power levels indicated by the DUT,
after executing zeroing and the true zero power. Ideally, this difference should be
zero.
This performance verification requires the following equipment:
– power meter (E4416/7A)
Procedure
