See “Power Requirements” on page 2for more information.
Instrument Maintenance
Protecting against overpowering
The input circuitry of the test set can be damaged by applying signals that exceed the maximum safe input
level of +27 dBm average total power or +/- 30 VDC. Repairing damage to the input circuitry can be
expensive. If the test set will be used to measure signals which might be near the maximum safe input
level, use external attenuators and/or limiters to help protect the test set input. Always use the three-
prong AC power cord supplied with this product. Failure to ensure adequate earth grounding by not using
this cord can cause product damage.
WARNING
If this product is not used as specified, the protection provided by the equipment
could be impaired. This product must be used in a normal condition (in which all
means for protection are intact) only. Install the instrument so that the detachable
power cord is readily identifiable and easily reached by the operator. The detachable
power cord is the instrument disconnecting device. It disconnects the mains circuits
from the mains supply before other parts of the instrument. The front panel switch is

Cleaning the instrument
WARNING
To prevent electrical shock, disconnect the test set from mains before cleaning. Use a
dry cloth or one slightly dampened with water to clean the external case parts. Do not
attempt to clean internally.
Cleaning connectors
Cleaning connectors with alcohol shall only be done with the instrument power cord removed, and in a
well-ventilated area. Allow all residual alcohol moisture to evaporate, and the fumes to dissipate prior to
energizing the instrument.
WARNING
Keep isopropyl alcohol away from heat, sparks, and flame. Store in a tightly closed
container. It is extremely flammable. In case of fire, use alcohol foam, dry chemical, or
carbon dioxide; water may be ineffective.
Use isopropyl alcohol with adequate ventilation and avoid contact with eyes, skin, and
clothing. It causes skin irritation, may cause eye damage, and is harmful if swallowed
or inhaled. It may be harmful if absorbed through the skin. Wash thoroughly after
handling. In case of spill, soak up with sand or earth. Flush spill area with water.
Dispose of isopropyl alcohol in accordance with all applicable federal, state, and local
environmental regulations.
Protecting against electrostatic discharge
Electrostatic discharge (ESD) can damage or destroy electronic components (the possibility of unseen
damage caused by ESD is present whenever components are transported, stored, or used).
Test equipment and ESD
To help reduce ESD damage that can occur while using test equipment:
•Before connecting any coaxial cable to a test set connector for the first time each day,
momentarily short the center and outer conductors of the cable together.
•Personnel should be grounded with a 1 MΩ resistor-isolated wrist-strap before touching the
center pin of any connector and before removing any assembly from the test set.
•Be sure that all instruments are properly earth-grounded to prevent build-up of static charge.
Additional information about ESD
For more information about ESD and how to prevent ESD damage, contact the Electrostatic Discharge
Association (http://www.esda.org). The ESD standards developed by this agency are sanctioned by the
American National Standards Institute (ANSI).

NOTES:
1. Reference clock Ports: Use the 10 MHz Clock Port to synchronize all system clocks of the units. Use
the Output Port if you want to supply other units or the DUT (Device Under Test) with the
instrument's clock. Use the Input Port if you want to provide one of the other unit's or the DUT’s
clock to the instrument.
2. Trigger ports: Use the Trigger Port to synchronize the LTE radio frame of the instrument in Emulator
mode with the DUT. Use the Output Port if you want to apply the synchronization signal from the
instrument to the DUT. Use the Input Port if you want to apply the signal from the DUT to the
instrument.
3. Fan Switch: Set the fan on High for maximum cooling performance. Select Auto for improved
acoustic performance. When set to Auto, the fan speed is determined by the instrument intake air
temperature.
4. The main power cord can be used as the system disconnecting device. It disconnects the mains
circuits from the mains supply.
WARNING
Do not cover or block the air flow vents.
