8-VSB, QAM A/B/C and NTSC Analysis
and Monitoring Hardware / Software Bundle
The DTU-236 RF Probe and RFXpert software is a comprehensive solution
designed to provide real-time analysis and monitoring of terrestrial signals
(8-VSB, QAM A/B/C and NTSC RF channels). The RFXpert software
is intended to be loaded by the end-user on a PC or laptop and work in
conjunction with the DTU-236 RF Probe. RFXpert provides complete RF
analysis and logging, along with transport stream recording.
The DTU-236 can be combined with Sencore’s RFXpert software for a truly
powerful RF measurement tool. RFXpert provides easy-to-read spectral displays,
both constellation and eye diagram displays, and the ability to turn off and on
8-VSB tap equalization to see the uncorrected signal being received.
◦ 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.
RFXpert Software
Adding StreamXpert to a DTU-236 makes for a cost-effective and user-friendly
MPEG-2/H.264 transport stream analyzer. Signals can be analyzed from either
the ASI or RF inputs of the DTU-236 and can be validated against industrystandard ETR101-290 templates. Transport streams can also be captured in the
field with StreamXpert for later use.
◦ Real-time analysis, monitoring and recording of MPEG-2/H.264
◦ PCR Accuracy and ETR101-290 checking
◦ Integrated MPEG-2 video and audio decoding with AC3 and
Dolby Digital+ Support

*Hyper threading CPU yields best results*
**Or equivalent AMD processor**
RAM: Disk Drive: 256 MB minimum
Best results (HD) with 512 MB+ dual channel DDR400
Rates > 40 Mb/s use drive separate\
from Operating System
Rates ≤ 100 Mb/s use single 7200 RPM SATA or SCSI
Rates > 100 Mb/s use single 15000 RPM SCSI, Striped 7200 RPM SATA, or Striped SCSI*
*Best performance is achieved using Striped (For Stream Recording)
SATA or SCSI Drives*
Note1: Parallel ATA Drives may be used, but
usually do not achieve same performance as
Note2: Drive specifications are
recommendations. Different architectures
will yield different results in some systems.
When in doubt, refer to drive/motherboard
specifications or contact a Sencore
