Tektronix (Microwave logic) ST112 Tx/Rx

The Tektronix/Microwave Logic ST112 SONET Transmission Test Set is an extensive SONET STSX-1, OC-1, OC-3, OC-12, signal analyzer and generator for tributary and network testing. DSX-1 ans DSX-3 Asynchronous Cross Connect Testing capabilities can be used independently or integrated with SONET testing capabilities. Designed for both field and lab use, the Test Set extends SONET Testing Technology by delivering a clear channel STS-3c and STS-12c concatenated mappings in addition to the standard DS# and VT1.5 mappings.
