ELECTRONIC MEASUREMENT NEWS No. 08 

Editorial 

Ladies & Gentlemen: 

As the days become shorter and nature 

turns purple and colourful, we know, 

autumn has arrived. Yes, we entered the 

last quarter of the year, which is 

traditionally the busiest period of the 

year for us. After all, long planned 

investments need to be executed, ideally 

all delivered before the end of the year in 

order to make use of the budget 

allocated. 

For orders placed within October or early 

November, usually we can meet the 

requested delivery time. However, as we 

move on towards the end of the year, we 

advise customers to look at one of our 

demo units as an alternative to a new 

instrument. During the 4th quarter we 

renew our pool of demo instruments, thus 

we are in the position to satisfy even very 

short term deliveries. All our demo 

instruments for sale are in perfect 

condition, most of them “like new”, and 

they are backed with a standard one-year 

warranty. 

Demo units with software options may 

be configured to customer's specific 

requirements by adding or deleting 

certain options. In any case, besides fast 

delivery, customers benefit from the most 

attractive discounts that are available for 

our demo instruments. For further 

information, please visit our web site and 

check our demo sell-off list for models 

available and pricing. 

Yours sincerely,

Remote Radio Heads (RRHs) 

in Wireless Mobile Networks 

Mobile wireless networks are constantly 

evolving, so that users get new and better 

services. This requires continuous 

investments by the operators, who at the 

same time are fighting for each and every 

subscriber with most attractive tariffs. 

While this is fine for the users, as they 

get good services at low fees, this means 

a constant challenge for the operators, 

who are trying very hard to get the best 

from their network at affordable prices. 

. 

One of the latest developments which 

help operators to run their networks more 

efficiently, are the so called Remote 

Radio Heads (RRH). 

. 

In a traditional base station set-up, the 

Node B, which is located in a container 

on the ground, is connected to the 

antenna via RF coax cables, including a 

Tower Mounted Amplifier (TMA). The 

typical loss between a Node B and the 

Antenna is in the range of 3.5dB. 

. 

A base station that uses a Remote Radio 

Head offers several significant 

advantages compared to a traditional 

Base Station setup. A so called Radio 

Server is connected via optical fiber with 

the Remote Radio Head (RRH). Typical 

distances between the Radio Server on 

the ground and the antenna tower 

introduce insignificant loss on the optical 

fiber so that we can truly say it is a “loss

less” connection. Since the RRH is 

typically located on the antenna tower 

and close to the antenna, there is no need 

for a TMA. The only loss that is 

introduced is the connection between the 

RRH and the antenna, which is still done 

using a RF cable. With values of typically 

0.5dB, this means a 3db (50%) difference 

in the power levels transmitted by the 

Base Station! In other words, using a 

RRH, the power efficiency of the Base 

Station becomes 

much higher. This is 

only one advantage 

that speaks for using 

Remote Radio 

Heads. Besides that, 

due to the reduced 

power needed for 

transmission, less 

energy is required 

for cooling. 

Moreover, optical 

fibers are less 

expensive than RF cables, and TMAs are 

not required at all. That all adds up to 

significant cost savings. Therefore, 

“traditional” Base Stations are often 

replaced by Base Stations that use 

Remote Radio Heads, since the 

investment pays off in relatively short 

time. 

. 

. 

Testing Remote Radio Head 

Base Stations 

Up to now, technicians dealing with 

installation and 

maintenance of Base 

Stations typically 

have used a tool to

check RF 

parameters of the 

RF cable between 

Node B and 

Antenna. (e.g. a 

Cable / Antenna 

Analyzer for Fault 

Location Analysis, 

Loss Measurements, 

etc.). With RRHs, an 

optical cable tester 

is required as well. 

. 

Source's 

Spectral 

Density 

Using a classical 

OTDR (Optical 

Time Domain 

Reflectometer) for 

the verification of 

the fiber between 

radio server and 

RRH can be 

TDR 

difficult, due to the attenuation dead zone 

of the OTDR. 

. 

Anritsu has developed a solution, which 

overcomes this issue by using an 

approach that is different from the 

measurement as done with a classical 

OTDR. 

. 

The ODTF-1 module, especially designed 

for Anritsu Site Master and BTS Master, 

is using FDR instead of TDR as used 

Less than 2% of 

TDR source energy 

is in the RF bands 

f1 

with OTDRs. Deadzones in an OTDR 

occur due to the reflected signals that 

saturate the photo receiver. The saturating 

signal is caused by high level optical 

pulses that are reflected due to the 

backscatter, which is dominated by low 

frequency content. In the frequency 

domain the photo receiver is only 

sensitive to optical signals with 

modulation in the microwave range. 

Thus, the photo receiver is not affected 

by backscatter overloading the receiver. 

Thus, with FDR there is no deadzone. 

. 

Anritsu Site Masters or BTS Masters 

equipped with the Optical Distance-to- 

Fault module ODTF-1 are the ideal test 

solution for Base Stations with RRH, 

since they perfectly combine a complete 

suite of test capabilities for RF coax 

cables and optical fibres all in a single 

handheld instrument. Thus, network 

operators, installers and maintenance 

technicians of base stations have to carry 

only one single light-weight instrument 

that is capable to analyze all parameters 

of any base station.

ODTF-1 

Optical Distance-to 

Fault Test Module for Site 

Master and BTS Master 

.

. 

As mentioned in the technology article, 

many operators are moving towards 

implementation of base stations that 

utilize Remote Radio Heads. Anritsu's 

Optical Distance to Fault (ODTF) module 

addresses the need of these operators, as 

well as the need of installers and 

maintenance technicians to find the 

location of faults on RF cables AND on 

optical fibers. 

. 

The ODTF-1 uses wavelength of 1550nm 

to characterize Single Mode Fibers. 

It 

allows customers to make highly 

accurate measurements of fibers with a 

maximum distance of 1020m, 

with an 

event resolution of 10cm. 

Due to the 

measurement technique used by the 

ODTF-1, even the first centimeter of 

fibers can be tested accurately, because 

there are no deadzones, 

like usually 

found in standard Optical Time Domain 

Reflectometers (OTDRs)! 

. 

Technicians trained in the RF world will 

be able to start working with an ODTF-1 

equipped Site Master or BTS Master 

right away, since the RF Distance-to- 

Fault and the Optical Distance-to-Fault 

measurement modes are identical in their 

appearance and the results can be 

interpreted the same way. 

. 

Customers can upgrade their existing 

S331D/S332D Site Masters or MT8222A 

BTS Master cost effectively for optical 

fiber measurements by simply adding the 

ODTF-1 module.

CMA5000A 

Multi-Technology Network 

Test Platform 

The CMA5000A is the successor to 

Anritsu's well established CMA5000 Test 

Platform. Similar like its predecessor, the 

CMA5000A is a portable, battery 

operated platform for testing a variety 

of transmission systems including 

Ethernet (from 10M to 10GE LAN 

and WAN) 

PDH/SDH/SONET (from E1/DS1 

to STM-64/OC-192) 

OTN (OTU-1 and OTU-2) 

Moreover, it is also capable to 

characterize optical fibers, including 

measurement of 

Fault Location (OTDR Optical Time 

Domain Reflectometry) 

Optical Spectrum Analysis (OSA) 

Polarization Mode Dispersion (PMD) 

Cromatic Dispersion (CD) 

The CMA5000A offers several improvements 

over the CMA5000, such as: 

Improved Touch Screen offering 

better readability even under direct 

sunlight 

Four USB2.0 ports for increased 

connectivity and usability (e.g. 

keyboard, mouse, printer, memory 

devices, etc ...) 

Built-in DVD, CD-RW drive 

Improved, more powerful CPU 

and more … 

The CMA5000A accepts all test modules 

that have previously been designed for 

use with the CMA5000.
