U3042AE12 Operational Check
Operational Check Procedure
The sequence of this procedure is very important and must be followed or the performance
accuracy and results may vary from the reference plots provided. Ensure that the test set
is not connected to the PNA if you are performing a PNA Operator’s Check. The PNA will
indicate false failures if the test set is connected.
