Tips for Preventing Damage to
Communication Test Set
Popular Agilent models: E5515A/B/C/T
Ensure proper grounding
• Always use the three-prong AC power cord supplied with
the instrument.
• Proper grounding of the instrument will prevent a build-up
of electrostatic charge which may be harmful to the
instrument and the operator.
• Do not damage the earth-grounding protection by using an
extension cable, power cable or autotransformer without a
protective ground conductor.
• Check AC power quality and polarity; typical AC voltage
required is 100 V, 120 V, 220 V ±10 % or 240 V +5 %/
-10 %. Typical expected grounding wire resistance is
< 1 Ω, the voltage between neutral and ground line is < 1 V.
Install uninterruptible power supply [UPS] if necessary.

Read the warning labels and specifications
• Do not exceed the values provided in the specifications
guide or as indicated by the yellow warning labels on the
• Refer to the specification guide for conditions required to
meet the listed specification. Note information regarding
stabilization time, instrument settings and calibration/
alignment requirements.
• For example, E5515 RF OUT ONLY (maximum power
250 mW peak), RF IN/OUT (maximum power 5 W peak),
Audio Input (30 V peak), Audio Output (12 V peak).
Avoid overpowering the test set
• Avoid front end damage by having some idea of the signal
level to be measured with the test set. Overpowering the
front end can damage the front end components.
• Before turning on or turning off the connected equipment
or the DUT, reduce the signal level to the minimum safety
level. This should help to prevent unexpected voltage swell
or sag affecting the input or output of analyzer.
• Properly apply a DC block, limiter or external attenuator as
needed. For more info visit
• For example, Agilent 11867A RF limiter is available to
provide input protection. It will reflect signals up to a level
of 10 W average power and 100 W peak power. 11867A
will provide input protection, within the specified frequency
range for the attenuator and mixer for many spectrum
analyzer applications.
• 11742A blocking capacitor blocks DC signals below 45 MHz
and passes signals up to 26.5 GHz. Ideal for use with high
frequency oscilloscopes or in biased microwave circuits,
it will suppress low frequency signals that can damage
expensive measuring equipment.
Protect the RF input connector
• Be careful not to bend, bump or flex any device under test
(DUT) connected to the input of the instrument (such as
filters, attenuators, or large cables). This will reduce the
amount of strain placed on the input connector and the
mounting hardware.
• Ensure externally connected items are properly supported
(not freely suspended) from the input.
• Always use torque wrench and gauge tools for connecting
RF connectors.
• Do not mix using 50 Ω and 75 Ω connectors and cables.
Follow proper RF cable and connector
• Avoid repeated bending of cables; a single sharp bend can
damage a cable instantly.
• Limit the number of connections and disconnections to
reduce wear.
• Inspect the connectors prior to use; look for dirt, nicks, and
other signs of damage or wear. A bad connector can ruin
the good connector instantly.
• Clean dirty connectors to prevent poor electrical connections and damage to the connector. For more cable and
connector care tips refer to Application Note 326 found at
Follow electrostatic discharge precautions
• Electrostatic discharge (ESD) can damage or destroy
electronic components.
• Whenever possible, conduct testing at a static-safe workstation. Keep electrostatic-generating materials at least one
meter away from all components. Before connecting any
coaxial cable to an analyzer, momentarily short the center
and outer conductors of the cable together.
• Install ESD protective covers on all RF connectors prior to
shipping and moving equipment.

Use proper lifting techniques
• Lift the instrument by the handles when transporting.
• Avoid picking up the instrument with your hand over the
front panel. If the instrument slips, damage may occur to
the keypad, knob, or input connectors.
• Use a cart or two persons to help move any heavy
Use proper packing for transport
Instrument damage can result from using packaging materials other than those specified. Never use styrene pellets in
any shape as packaging materials. They do not adequately
cushion the equipment and can cause equipment damage by
generating static electricity. If possible, retain the
original packaging for re-use when shipping the instrument.

Check for proper ventilation and humidity
• Periodically check and clean the cooling vents of the instrument.
• Inadequate airflow can result in excessive operating temperatures which can lead to instrument failures.
• Optimal operating temperature is 23 °C to -5 °C, always
keep instrument ambient temperature at < 35 °C.
• When installing the product in a cabinet, the convection
air currents in and out of the instrument must not be
restricted. The ambient temperature must be less than the
maximum operating temperature of the product by 4 °C for
every 100 W dissipated in the cabinet. If the total power
dissipated in the cabinet is greater than 800 W, then forced
convection must be used.
• For E5515, air flows from right side to left side (facing front
panel). Approximately 170 CFM.
