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.
