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 a power meter (E4416/7A).
Procedure
1 Connect the DUT (E-Series E9300 power sensor) to the power meter as shown
Figure 4-1
2 Warm up the DUT for approximately 30 minutes.
3 Connect the DUT to the power meter power reference terminal to perform zero
For E9300B series, the high power attenuator must be removed.
