Transmission Measurement
As a transmission measurement example, I decided to characterize the two crystal filters in my ICOM 706MKIIG radio. I was not able to find the specifications of the input and output impedance for the ICOM products, but the INRAD web site did describe their ICOM replacement filters, and I assumed a similar port impedance (2000 Ohms).
