Digital Reprogrammable Software Radios R&S M3SR 5
Built-in test (BIT) concept
An efficient BIT concept allows identifica-
tion and location of functional failures
down to module level. All failures
detected during the test can be indicated
locally and remotely.
◆ Power-up BIT (PBIT)
Automatic test after power-up of the
unit
◆ Continuous BIT (CBIT)
Automatic start after successful PBIT
and continuous and automatic moni-
toring of all modules including radio
basis during operation
◆ Initiated BIT (IBIT)
Interactive test in non-operating
status to support maintenance of the
radio units; can be triggered locally or
remotely; test and analysis of the
signal path in the radio with the aid of
test signals without disconnecting the
antenna connector (test signal gener-
ator already built in; simplified diag-
nostics possible without opening the
unit)
Radio failure archive
All failures detected and error messages
are stored in the radio failure archive. The
archive can be read locally on the CCP
and remotely. Each entry also contains a
description in plain text.
Inventory report
The software and hardware states of the
radio system are entered in full detail into
the inventory report. The report allows a
fast overview of the total configuration
status without having to open the unit.
Power supply concept
Transceivers and transmitters are sup-
plied from DC. The external Universal
Power Supply R&S IN4000A or other
AC/DC sources provide AC supply for the
radios.
Receivers and multireceivers have an
integrated AC/DC power supply
(R&S IN4400A).
