■ “Pass-Through” mode, which allows the input video signal to
appear at the generator output, permits switching between full
field test signals and program video, without the need for an
external switcher. In a typical operation, RG-400 Reference
Overlay is used to adjust video levels and color settings on the
TBC or color corrector. Test signals from the RG-400 are then
recorded onto the tape leader. Once levels have been set up and
verified, the RG-400 is placed in Pass-Through mode to record
the program video.
■ LCD screen displays a menu showing test
signal sets presently “resident” in the unit
and a sub-menu which provides various
configuration selections. You can also
determine initial settings for ext. reference
(if present), trigger output, and APL lev-
els.
■ Timing changes may be made to the test
signals and independently to the
pulse/black burst outputs with respect to
the selected reference: the frequency of
the master oscillator may also be adjusted
to more nearly match a known standard.
Selections for bounce rate, audio tone fre-
quencies and levels, character ID, and
countdown timing can also be made .
■ Depending on the complexity of the for-
mats and signals involved, more than one
signal family may reside simultaneously
in the downloaded memory A user defin-
able two-line ID of 24 characters per line
may be placed on the video output.
■ Memory cards makes the Signal Creator a
go-anywhere generator. For example, one
card can have a selection of signals which
would be useful for end-to-end testing of
the signal processing path. Another could
be a standard “checklist” of signals to be
stepped through easily and quickly.
Equipment manufacturers and systems
designers could group specialized tests for
different pieces of equipment into fami-
lies, for streamlined QC and testing.
■ Built-in safety features include passcodes
to block unauthorized users from chang-
ing timing settings or signal sets. Cards
can also have individual users’ IDs.
■ Simultaneous analog and digital outputs
are offered, as well as a separate output of
NTSC SMPTE bars which is indepen-
dent of the downloading process.
Programmable analog outputs are 10-bit
Configuration Options
SC-P: Basic unit generates composite
NTSC and PAL, and all analog component
signals:
SC-STD: Same as above plus it adds Black
Burst (BB) and Serial Digital Output (D1
and D2 in both serial and parallel). factory
installed options,
SC-DLX: Same as above plus it adds 12
MHz Sweep and Zone Pattern Outputs
Each comes bundled with Creator Software
allowing you to design test signals of your
own, group existing test signals into custom
sets of signals, load signal sets from a PC
directly to the Signal Creator, or load signal
sets onto a RAM card in the Signal Creator.
SIGNAL CREATOR
Multi-Format Test Signal Generator
Composite, component and digital formats stand alongside one another in
many facilities creating the need to work in multiple formats. Regardless
of the format in use, each has its own personality and have very different
test and measurement requirements. But space is at a premium, and gen-
erators dedicated to each format not only eat up rack space but require
multiple purchases. Signal Creator reconciles these elements using pocket-
sized memory (PCMCIA) cards. These cards are capable of holding up to 100 different test signals in memory. The sig-
nals used most frequently may be permanently downloaded to the generator’s memory, but the majority of the signals
reside on the card itself (as well as on floppy disk back-up). The added space is what allows Signal Creator to generate
signals for practically any current video format or standard including Betacam, GBR, and Dl , D2 digital formats.
