For those interested there was a long (over 300 posts) discussion of how to measure ceramic filters in another group about 5 years ago.
David Platt started it off and I have attached his 50 to 330ohm circuit that he used to measure a Murata 10.7 MHz. filter. In this case you do not need the PortZ function.
I have also attached a graphic showing how Murata suggests using series resistors to get the correct input and output impedance for measurement. The PortZ function will be useful in this case.
