Revision 3 1.0 DESCRIPTION Communism's NEWSCASTER VT1 series NEWSCASTER VT1 is a Digital-Analog ENG/OB Microwave Transmitter. The Mast Mounted Microwave Transmitter System is designed to operate in any specified band in the 1.00 to 15.5 GHz frequency range. Each unit is field programmable and configurable to meet a wide range of customer requirements.
Revision 3 Where: = mean frequency band center in GHz rounded to the closest GHz. This number is then multiplied by 10. For multiple bands, each center frequency designation is separated by a backslash "7". BB = See Power Output Designation table below: Power Output Designation E=5 Watt L=12 Watt CC = Nu comm assigns a frequency chart number for each unique frequency channel combination.
Revision 3 1.1. Features Configuration: Communism's NEWSCASTER VT1 Series Digits-Analog ~~ ENG/OB Transmitters are the most comprehensive ENG/OB radio in the world. Their features are designed for both Analog and Digital operation in such applications as ENG/OB trucks, portable links, helicopters, etc.
Revision 3 Audio Sub carriers: Two {four optional) field programmable synthesized audio sub carriers feature individual LINE/OFF/MIC/TONE source selection, level indicating bar graphs, and automatic gain control (AG. The sub carrier frequencies, Mode, and additional gain are front panel adjustable using the LCD interface. Standby Mode: in the Standby mode, the NEWSCASTER VT1 is powered on, but the RF output is muted, enabling the transmitter to be tuned safely without radiating off-frequency emissions.
Revision 3 1.3. Options + Test Pattern/[D Test Generator: The optional Test Generator provides: « SMOTE RS-170A Color Bars (EBU Pattern) * A 16-character programmable 1D: (This ID can be placed in the Vertical Interval and Gen locked to the incoming Video signal) * A Multidisciplinary Ramp test pattern s Pan & Tilt Controller * Remote Control Software: The NEWSCASTER VT1 can be full monitored and controlled from an IBM Compatible PC through a port. 1.4.
