Axcera unveils new low-power UHF and VHF transmitters
Transmission equipment provider Axcera is unveiling its second-generation, low-power transmitter line at the BroadcastAsia trade show this week in Singapore. The units can be configured as a television transmitter, regenerative translator or gap-filler.
The new Innovator CX is compact and addresses low power requirements where space and cost are a concern. This second generation design is available in a broad range of output power levels, from a few watts up to as much as 3400W. The VHF version is also new for this year, providing all of the same advantages as its UHF counterpart. Both are compatible with most any international digital or analog television standard, including ATSC, DVB-T, DVB-H, DVB-SH, CMMB (STiMi), DAB, T-DMB, ISDB-T/Tb, MediaFLO, NTSC, and PAL.
The Innovator CX offers many of the same features found in higher power transmitters, such as digital linear and nonlinear precorrection, a frequency agile exciter, broadband amplifiers and an available SNMP/Web browser interface. Designed for high availability, these transmitters offer features such as redundant (main/alternate) exciter/driver/control systems and parallel power supplies, power amplifiers and cooling. Cooling fans can be replaced from the front of the transmitter, simplifying maintenance.
