Rohde & Schwarz CMU 200 Service Manual

R&S CMU Instrument Design and Function Description
1100.4903.82 3.15 E-5
A microprocessor with peripheral equipment and two FPGA’s on the
UNIV. SIGN. UNIT control all the processes on the module.
A
n RS232 interface is available for debugging, data input and output.
Besides, an ISA bus interface is installed for control and data
communication with the FRONT MODULE CONTROLLER.
DSP MODULE
The two sandwich DSP MODULES (DSP MODULE0 and DSP
MODULE1) are directly inserted on the UNIV. SIGN. UNIT via four
multipoint connectors. Via a FIFO device, they receive the digital I/Q
data from the DIGITAL BOARD for evaluation. The signal can then be
demodulated by the DSP MODULES and the demodulated data can be
passed on the protocol engine running on the MC or a DSP MODULE.
The DSP MODULES can also perform some measurements and the
results are passed on via the ISA bus interface to the FRONT
MODULE CONTROLLER.
Likewise, the DSPs cause further actions on the transmitter side (TX),
e.g. change transmit frequency-settings via the FPGA 'XILINX2' and
output analog I/Q data via the IQOUT MODULE.
Option BLUETOOTH
MODULE
R&S CMU-B53 Var02
The option BLUETOOTH MODULE R&S CMU-B53 Var02 is directly
inserted on the UNIV. SIGN. UNIT. It performs BLUETOOTH
functionality.
Attention: This option includes the functionality of option SPEECH
CODEC R&S CMU-B52 Var02. Therefore it is not necessary and
possible to fit additionally the option SPEECH CODEC R&S CMU-B52
Var02.
IQOUT MODULE
The sandwich IQOUT MODULE is directly inserted on the UNIV. SIGN.
UNIT via three multipoint connectors and installed in an extra shielding
chamber, since it performs the digital-to-analog conversion of the I/Q
data.
Option SPEECH CODEC
R&S CMU-B52 Var02
The Option SPEECH CODEC R&S CMU-B52 Var 02 (including DSP
MODULE3) is also designed as sandwich module and is directly
plugged onto the UNIV. SIGN. UNIT via three multipoint connectors.
This option permits to read in and output analog speech signals
(handsetin/out lines) via A/D and D/A converters.
