The N5251A is a 2-port or 4-port vector network analyzer system with an extremely wide
frequency range of 10 MHz to 110 GHz. The N5251A uses the same 1.0 mm test port
connections throughout its entire range of test frequencies. It is never necessary to make and
break connections to complete a test.
The illustration below shows the N5251A configured for coaxial measurement. The system can
also be configured for on-wafer measurement using a wafer probe test station.
