FACTORY SEALED (hard to take a good pic w/o tearing open)

NO RETURNS, NO REFUNDS, NO CREDITS OR EXCHANGES IF PACKAGE IS OPENED.

The 22 Series Open/Shorts are used on the test port of an SWR Autotester or SWR bridge to establish a full reflection reference for accurate SWR measurements. When used with scalar network analysers, the open and short reflections over a swept frequency range can be automatically averaged to enhance measurement accuracy. All models consist of an open on one end and a short on the other.
