D DVB-T Receiver USB Probe
DTU-235
DVB-T Receiver USB Probe
The DTU-235 provides a portable field solution to
tune QPSK or QAM COFDM frequencies directly
on your laptop for easy field testing or recording.
Combine the DTU-235 with RFXpert for a
comprehensive and economical MPEG2 analysis
solution.
• Light-weight, easy-to-use RF adapter for tuning to any
UHF/VHF channel in the 50 to 860 MHz range
• Record MPEG2 Transport Stream directly to a laptop PC for
easy field recording
• Full portability that requires no additional power supply
or batteries, the DTU-235 operates entirely from a USB-2
connection
• Sensitive front-end allowing reception of RF signals from
-25 to +50 dBmV
The DTU-235 can be combined with Sencore’s
RFXpert software for a truly powerful RF
measurement tool. RFXpert provides easy-toread spectral displays, both constellation and eye
diagram displays.
• True demodulated digital reading for MER, Pre-BER, Post
BER and EVM
• A proof-positive method of signal documentation or
drop-point comparisons with programmable, user defined
logging and auto-inspection capabilities.
Adding StreamXpert to a DTU-235 makes for a
cost-effective and user-friendly MPEG2/H.264
transport stream analyzer. RF inputs of the
DTU-235 and can be validated against industry
standard ETR101-290 templates. Transport
streams can also be captured in the field with
StreamXpert for later use.
• Real-time analysis, monitoring and recording of
MPEG2/H.264
• PCR Accuracy and ETR101-290 checking
• Integrated MPEG2 video and audio decoding with AC3
and Dolby Digital+ Support
