FEATURES
* Stabilized, compact, and lightweight design. * A board-in type mountable directly on the mother board of the set. * Bus noise elimination through the use of a built-in white clip circuit. * Usable for many purposes such as BS, CATV, etc., in addition to VCR and laser disc.
RF Modulator
appear on the RF output when the modulator portion is not operating, allowing for transparent operation with other household video appliances. When the modulator is in use, the modulated signal is seen at output and the antenna input spectrum is suppressed. A tuner-out port is included in the VT5F9MN0007 as this unit is intended for applications where a local tuner capability is desired, such as in a combine VCR product. The tuner-out port is a sample of the antenna input spectrum and is always active. The modulator may also be used in satellite television applications. The output channel may be selected between NTSC channels 3 and 4, as designated in North America. The modulator operates from a +5 V source.
FUNCTIONAL DESCRIPTION
This modulator is designed for operation in NTSC-M systems. An RF antenna input is provided by an F Female connector and the combined RF output is provided on an F connector. The antenna input signals
