Engage
Imagine you are tasked with
diagnosing a network issue in a large
office environment where multiple
computers are experiencing
connectivity problems.
How would you approach this
situation using the tools and test
equipment?

GROUP 5
In a computer maintenance workshop, cables are often scattered
and disorganized, making it difficult to identify connections and
troubleshoot effectively. During a routine check, a technician
notices that the network cables in a server rack are tangled and
loosely hanging, posing a risk of accidental disconnection and
signal interference.

ADVANCED TOOLS AND TEST EQUIPMENT
A network analyzer, also known
as a network protocol analyzer or
packet analyzer, is a specialized
tool used in networking to
monitor, capture, analyze,
and troubleshoot network traffic
and protocols.
Its primary purpose is to provide
detailed insights into network
performance, diagnose network
issues, and optimize network
efficiency.
Extend
ADVANCED TOOLS AND TEST EQUIPMENT
An oscilloscope is a versatile
electronic test instrument used
in various fields, including
electronics,
telecommunications,
engineering, and physics.
Its primary purpose is to
visualize and analyze
the waveform of electrical
signals over time.
Extend
ADVANCED TOOLS AND TEST EQUIPMENT
A cable certifier is a specialized tool
used in networking and
telecommunications to certify the
performance and compliance of network
cables.
Its primary purpose is to ensure that
installed cables meet industry standards
and are capable of supporting highspeed data transmission without errors
or signal degradation.

REFLECTION
Direction: Please provide a possible solution/s to the situations given.
1. Describe a real-world network troubleshooting scenario
where you would use specific tools and test equipment
discussed in class.
2. Analyze a captured waveform or network packet using an
oscilloscope or network analyzer. Describe the key
parameters you would examine, such as amplitude,
frequency, timing, or protocol details.

Possible Solutions:
1. Implementing Solutions:
 Implement corrective measures based on the identified root causes, such as optimizing network
settings, updating firmware, or replacing faulty hardware components.
 Configure Quality of Service (QoS) settings to prioritize critical traffic and improve overall
network performance.
 Conduct thorough testing and monitoring to ensure that the implemented solutions resolve the
connectivity issues effectively.
2. Packet Capture and Import:
 Start by importing the captured packet file (.pcap or .cap format) into the network analyzer
software
for analysis.
 Ensure that the software is configured to display relevant protocol details, packet headers,
payload data, and timing information.
