The 7T11 Sampling Sweep Plug-In is a timebase module that provides equivalent-time and real-time horizontal deflection for single-trace or dual-trace vertical sampling modules for use in the Tektronix 7000-Series mainframes. The unit provides 10 ps/div to 5 ms/div time positions with ?3% accuracy. The triggering range is from approximately 10Hz (the sequential mode) to above 12.4GHz. No pretrigger is required as the 7T11 has an internal trigger source from 5kHz to 500MHz. The unit has an external HF sync from 1GHz to 12.4GHz and a positive pulse amplitude of at least 400 mV into 50-ohms with a risetime of better than 2.5 ns. The 7T11 is a companion unit for the 7S11 (sold separately).
