Tektronix 7S12 Highlights
The 7S12 is a plug-in for TDR analysis (= time Domain Reflectometrie), it can be used in each 7000er Mainframe without losses of bandwidth. An electric signal has wave character, cable medium change (connectors, interruption, short-circuit .....) partially reflects. Around these places TDR measurements with extremely fast impulses will locate accomplished. In addition, normal measurements of electrical signals (so of the 7S14) can be accomplished. For this reason the 7S12 has space and powers two exchangeable heads. Around saltuses in the reflected signal to locate temporally exactly the 7S12 has a rolled metal band scale (like also the SG504) operated by a crank. It offers the necessary resolution to find the failed cable and the position.
