The TA340 is a premium PC3.5(f) to PC3.5(f) test port adaptor that allows a female test port to be changed to a male test port. PC3.5 connectors offer closer impedance tolerance than SMA.

Using test port adaptors to change the gender of the test port is an easy and economical way to interface with both male and female DUTs. Bear in mind, however, that adding an adaptor increases measurement uncertainties.
