I. DTXPRO-10U INTRODUCTION
The DTXPRO-10U transmitter is an integrated transmission system. Included in a 19 inch 13 RU
rack is a modulator, power amplifier, mask filter, and standard accessories. The DTXPRO-10U is
tested to FCC specifications. The modulator used in this assembly is the DXDPRO-10U. The
DXDPRO-10U is a wide-band UHF modulator with adaptive linear and non-linear correction
controllable via an Ethernet IP connection. Many additional features are included in this basic
modulator such as transmitter remote control and status monitoring, GPS receiver, ASI or
SMPTE 310M, and fault notification via email.
The DXDPRO-10U is an all-channel modulator with adaptive linear and nonlinear correction
controllable via an Ethernet IP connection. The DR100PRO-U provides power amplification to
achieve the desired power output level to comply with FCC license requirements. LDMOS 50 volt
device technology is used throughout the HPA section for state-of-the-art performance. This unit
is wired to operate off 48V DC or 110V AC. The 48V DC is automatically switched on in case the
AC mains fail. This feature is activated only if a 48 VDC auxiliary power source is available.
An FCC compliant stringent mask filter is supplied and is built into the rack. Additional
components are included to sample forward and reflected power as well as samples for the
adaptive linear and non-linear corrector. The system transmitter is protected using an isolator
between the mask filter and the HPA. Any failures in the filters or antenna will be detected by the
onboard protection circuits. This transmitter includes a low pass filter for additional harmonic
suppression in the GPS bands.
Pineapple Technology, Inc. warrants the DTXPRO-10U for two (2) years from ship date. An
extended warranty is available for an additional five (5) years. Contact PTI sales for details.
