Section 1 Introduction
Platinum VAX-C Series
1.4 Transmitter Models
VAX-C transmitter model numbers are formed based on the following:
‘V’ stands for VHF Band, while ‘A’ means that air is used for cooling, ‘X’ indicates that
the unit is a TV Transmitter, and ’C’ stands for compact class. The number following
the VAX prefix stands for the transmitter power level. The suffix indicates the
modulation type. The suffix ‘AT’ indicates ‘ATSC’. Other abbreviations include: MH
for ATSC Mobile Handheld, DV for ‘DVB-T/H’, T2 for DVB-T2, IS for ’ISDB-T’, CT
for CTTB, CM for ’CMMB’, DA for DAB, and DM for DMB digital modulations
standards. The suffix set will be extended for additional modulation standards as
required.
For example:
VAX-180AT-C = VHF, air cooled, TV transmitter, 180W, compact class, ATSC (digital)
VAX-100DV-C = VHF, air cooled, TV transmitter, 100W, compact class, DVB-T
(digital)
The Platinum VAX-C Compact Class transmitters are available in four air cooled power
levels. The models are listed below in Table 1-1.
