T-BERD®/MTS-5800 Network Tester
CPRI Check, RRU Testing with ALU BBU Emulation and
RF over CPRI Spectrum Analysis
This quick card describes how to connect to a ALU CPRI Remote Radio Unit (RRU) and configure a T-
BERD 5800v2 for CPRI Testing including BBU Emulation and RF over CPRI Spectrum Analysis.
Equipment Requirements:
•RRU with power
•T-BERD/MTS-5800v2 equipped with:
oBERT software release V27.1 or greater
oCPRI test options:
▪C512GCPRI for CPRI Rate 2 (1228.8M)
▪C524GCPRI for CPRI Rate 3 (2457.6M)
▪C549GCPRI for CPRI Rate 5 (4915.2M)
▪C598GCPRI for CPRI Rate 7 (9830.4M)
▪C5RFOCPRI for RF over CPRI Spectrum
Analysis
▪C5RRHA for ALU BBU Emulation
•SFP or SFP+ optical transceiver that supports
the CPRI rate for the interface under test
•Single mode jumper cable to connect the
T-BERD/MTS to the interface under test
•Fiber optic inspection microscope
(VIAVI P5000i or FiberChek Probe)
•Fiber optic cleaning supplies
Figure 1: Equipment Requirements
Information Requirements:
•CPRI Line Rate
•RRH Bandwidth (MHz)
•Carrier Transmit Frequency (MHz)
•Carrier Receive Frequency (MHz)
Fiber Inspection Guidelines:
•Use the VIAVI P5000i or FiberChek Probe
microscope to inspect both sides of every fiber
optic connection being (bulkhead connectors,
patch cords, etc.)
•Focus the fiber on the screen. If dirty, clean
the connector.
•If it appears clean, run inspection test.
•If it fails, clean the fiber and re-run inspection test.
•Repeat until it passes.

Connect to Fiber Under Test:
1. Insert CPRI optics into the Port 1 slot on the
top of the T-BERD/MTS 5800v2.
2. After inspecting the fiber end faces, connect
the SFP/SFP+ to the fiber under test using an
LC-LC jumper cable.

Launch Test:
1. Press the Power button to turn on the
test set.
2. Using the Select Test menu, Quick Launch
menu, or Job Manager, launch the CPRI ►
Rates 1-7 ►CPRI Check ►Terminate test
on port 1.
3. Tap the bottom button to Start a
New Configuration.

Configure Test:
1. Tap the Far-end Device drop-down list and
select ALU.
2. The Local SFP Verification, Interface, Start-
up Sequence, and RTD tests will be
automatically selected and greyed-out.
3. Tap the checkboxes for all other desired
tests:
✓RRH Identification
✓Remote Electrical Tilt (RET)
✓Voltage Standing Wave Ratio
(VSWR)
✓Diversity Imbalance
✓PIM Detection
✓2-Tone PIM Analysis
4. Tap twice to proceed to the
RRH Transmit and Receive settings.

5. Configure RRH Transmit and Receive
Settings as follows:
•Default to Max. Tx Power: No
•Swap I and Q: No
•Bandwidth: 10MHz
•Carrier Tx Frequency (MHz): enter
the Transmit Frequency for the RRH
•Carrier Max. Tx Power (MHz): 40.0
•Carrier Rx Frequency (MHz): enter
the Transmit Frequency for the RRH
6. Tap , , and
to proceed to the Local SFP
Verification screen.

Local SFP Verification:
1. Select the CPRI Rate to test.
2. Verify that Signal Present, Sync Acquired,
and Frame Sync LEDs are all green.
•If any of the lights are red in color, the CPRI
Rate may be incorrect, the RRU may need to
be reset, or power may need to be cycled.
•If the Frame sync LED is red, the SFP may
not be in working order or it may not
support the selected CPRI Rate.
3. Press to proceed to the Run
CPRI Tests screen.

Run Test:
1. Tap to run the Interface,
Start-up Sequence, RTD, and RRH
Identification tests.
2. At the end of the test duration, Pass/Fail
status for each scheduled test will be
indicated by green checkmark, , or
red x, . Tests for which no pass/fail
threshold was specified will have a blue
checkmark, .
