   The Tektronix VITS100 is a Generator and Inserter that is designed for use in applications where, until now, cost has been a prohibitive factor. This includes VITS insertion on satellite uplinks, at cable system headends, on EFP vehicle outputs, on picture source outputs, and at the broadcast transmitter input. The Tektronix VITS100 provides a solid basic generator/inserter unit and a VM 700A compatible source identification which is useful in documentation of system performance. The VITS100 Generator and Inserter has a frequency response of 5.5MHz. The chrominance-to-luminance gain is 0.5% with a delay of less than or equal to 5 ns.

Test Signal Generator

   The VITS 100 uses 12-Bit, 8 FSC digital test signal generation to ensure test signal accuracy. The test signal complement includes the following:

  • NTC 7 composite and combination
  • FCC composite, multiburst, and color bars
  • Vertical interval reference signal (VIRS)
  • (Sin x)/x
Inserter/deleter Functions

   The VITS100 may be programmed to insert any test signal, or the source identification signal on any line from 17 through 20 of both fields. Delete and pass functions are available for the same lines as the insert function.

Program Channel

   Maintaining transparency and continuity of the program channel are prime considerations in the VITS100. Distortions and transients are virtually eliminated by the Tektronix developed channel switch integrated circuit. Insertion or deletion of VITS can occur only when genlock to the program input signal is attained. Loss of mains power or genlock causes the program line to be bypassed. Program signal delay in operate and bypass is matched.

Source Identification

   The VITS100 provides a one line 16-Bit source identification code. The bits may be set in any high/low sequence providing up to 65,536 possible codes. Setting of the code is done with DIP switches accessible through the rear panel. The identification signal may be placed on any of the available lines in vertical blanking. The VM 700A Video Measurement Set utilizes this signal for identification of sources on displays and print outs of measurement routines.
