7.2.3 Parameter Overview
Beside the main controls, like switching on the CPRI signal transmission, mode and save/
recall of settings, the interface is controlled by various parameters, which are grouped by
function:
Parameter Group Purpose Examples
Hardware Hardware information on the
R&S
EX-IQ-BOX and the CPRI
breakout board, the status of signal
transmission and hardware link
settings.
Hardware versions, CPRI mode,
Reference Clock, timing measure-
ments, line bit rate, input and out-
puts, GPIO settings.
L1 Analysis Link status information L1 inband protocol, status, local
and remote alarms, layer events.
Downlink/Uplink Signal definition for transmitting /
receiving signals to or from the
DUT, including graphical display of
the CPRI frames. Appending signals with copy func-
tion, signal source, digital stand-
ard, numeric format, allocation and
AxC container definition, low level
BER test and start conditions.
Control & Management Settings for slow or fast C&M inter-
faces, e.g. selecting the interface,
Ethernet pointer position, host
address or inserting control com-
mands directly. Slow C&M: Bit rate, HDLC status,
source or mode.
Fast C&M: Ethernet pointer, bit
rate, host, port and login data.
Command editor/edit field.
Vendor Data Vendor-specific information. The data table enables to send
binary raw data to the DUT, e.g., to
test functions like AGC.
Diagnostics Diagnostics on the link interfaces
and Tx / Rx test possibilities. Identifier, vendor, connector type,
transceiver type, module tempera-
ture, warnings.
Rx alarms, SFP module alarms.
ARB Table with information on the cur-
rently loaded waveform files. File name, option, sample rate,
samples, state and status display.
Recorder Settings for recording an I/Q signal
and storing the data in a waveform
file. Data source, recording length, trig-
ger, status display and file man-
agement
7.2.4 Control Elements and Connectors
This section explains the control elements and connectors of the breakout board for CPRI
applications, i.e. the R&S
EX-IQ-BOX option EXBOX-B85. With the help of the following
schematic view, the control elements and the connectors are briefly described, including
references to the chapters with detailed information.
