Description
The VT 1405 is a portable, easy-to-use, light-weight
test set designed to test and monitor MPEG
Transport Stream based equipment and systems.
The VT 1405 performs measurements utilizing
MPEG 2 transport bitstreams and industry
standard BERT (Bit Error Rate Test) procedures and
monitors key MPEG parameters for errors.
The VT 1405 generates MPEG data streams
consisting of user selectable PIDs and test
payloads which can be used for spot testing or
continuous monitoring. User data streams can be
generated by downloading MPEG2 compatible
streams into onboard flash memory. The pattern
and user streams are generated separately and
thus may have different transmit properties. PSI
table generation is supported and enables the
stream to be easily multiplexed into a system and
decoded by the VT 1405 by program number
instead of specific PID values.
The VT 1405 contains a receive and transmit
section. The transmitter outputs variable bitrate
streams from 25 Kbps up to 214 Mb/s. Single bit
errors can be inserted manually or automatically
in rates from 10 to 10 . Eight user selected
predefined patterns can also be inserted into the
MPEG payload and transmitted. The receiver
automatically synchronizes on the incoming
bitstream and decodes the patterns and checks
and counts for error conditions. Receive data
may also be captured into onboard RAM and
downloaded to a host system for further analysis.
An easy-to-read color LCD displays all of the
measured results and several LED indicators
provide status conditions at-a-glance.
