Manual Datasheet Specifications

The Tektronix DS1001 Television Demodulators is the answer to cable operators, broadcasters and manufacturers that need a low-cost, high-performance demodulator. They support television standard M/N and B/G.
 

The Tektronix DS1000 is full measurement grade demodulators, with specifications better than demodulators twice their size. Input sensitivity and other specifications make the DS1000 Series ideal for use as a repeater or as the analog front end of an RF-to-digital conversion system in all-digital cable systems. It can also act as a precision set-top converter for making baseband measurements in the field.
 

The Tektronix DS1001 is well suited for remote node monitoring. The addressable serial port allows remote control and status monitoring using computers and modems.
