2.3.1
STRATA TXU
The TXU (
) always contains an IF/RF module that
accepts either a 70 MHz COFDM, FMT IF, or external 70 MHz
input signal and up-converts these signals to the required RF
band. The RF frequency synthesizer circuit included in the IF/RF
unit, in conjunction with the command and control power supply
module, provides the means to channelize RF video and audio
signals in the TX System RF band.

band. The RF frequency synthesizer circuit included in the IF/RF
unit, in conjunction with the command and control power supply
module, provides the means to channelize RF video and audio
signals in the TX System RF band.
The TXU, with either an analog (FMT) or digital (MPEG/COFDM)
module, is integrated in the same housing as the HPU
components. This provides the ability to incorporate high RF
power output (12 watts of saturated RF power) into a single
analog or digital transmitter assembly.

Standard U.S. FCC band plans, as well as customer-created
channel plans, may be customized using the STRATA TX
Configurator software.

As noted previously, the TXU may also include either an MPEG/
CODFM or FMT module (but not both), in which case the TXU
serves as a stand-alone digital or analog video microwave
transmission system.

2.3.2
STRATA TCU
The TCU (
) may contain either
analog or digital or both analog and digital video modulation
modules. Where an application might initially employ only
analog video transmission but expects to migrate to dual,
switchable, analog and digital operation, the TCU may be
upgraded to add the MPEG/COFDM module to add this
capability.
