The Tektronix DS1000 Series Television Demodulators are the answer for cable operators, broadcasters and manufacturers that needs a low cost, high performance demodulator.  They support television standards M/N and B/G.

The Tektronix DS1000 Series Products are 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 DS1000 Series products are well suited for remote node monitoring. The addressable serial port allows remote control and status monitoring using computers and modems.

For a complete solution that includes a graphical display, the DS1000 Series can be combined with the Tektronix 1740A Combination Waveform/Vector Monitor.

Ghost Cancelling
The DS1001G incorporates state-of-the-art ghost canceling technology which improves overall video quality by using a specialized ghost canceling test signal, pre-inserted into the television signal by broadcasters, to automatically null out annoying static or dynamic picture "ghosts" caused by RF signal reflections from large buildings, trucks or changing weather conditions.

Audio Support
Audio support includes BTSC stereo for system M/N (DS1001A) as well as both FM (mono & dual tone) and NICAM support for System B/G (DS1002). The DS1001A audio outputs are through special terminal-block connectors, which provide simultaneous outputs of Left, Right and SAP audio channels. The DS1002 audio output is through 2xLR connectors. These connectors can be configured in a variety of ways (depending on system), including: mono, SAP, stereo right and left, both right or both left. The DS1001A also has a 4.5 MHz intercarrier output for driving an external aural modulation monitor.

Remote Programming
The DS1000 Series supports remote programming via either RS-232 or RS-485 at 9600 baud.  Most front panel controls can be accessed via the port.
