Confirm unfaded error-free performance
Some of these tasks may not be possible or practical within a bench test environment due to the
nature of the remote connectivity of peripheral equipment. However, it is good practice to
perform as much as possible in this environment to minimize field/installation time and
troubleshooting efforts.
Detailed performance measurements are usually not required for pre-installation, but can be
easily performed at this stage and may be helpful for later troubleshooting efforts or for internal
records. During troubleshooting, there may often be a point at which a back-to-back bench test
should be performed to verify many or all of the above items, and in the case of a suspected
faulty device, to help confirm the fault and determine which end of the system is at fault and in
need of repair or replacement.
See Back-to-back Bench Testing on page 82 for detailed instructions.
RF Output Power Setting
The maximum RF output power is bounded by one of the following criteria:
•
Maximum RF output power setting capability of the radio device
•
Maximum RF output power allowed/authorized by the local government regulations and for
this specific device
•
Maximum effective isotropic radiated power (EIRP) of the transmission system
allowed/authorized by the local government regulations and for this specific device
•
Desired RSL to not exceed the maximum RSL allowed by the device
•
Desired RSL to minimize/eliminate interference into neighboring systems
In many cases the radio must be pre-configured for legal maximum output power
before connecting to the antenna and transmission system. Instructions for
adjusting the output power can also be found in System Configuration Page on
page 44.
The following information pertains to specific regulatory requirements based on up-to-date
information for countries where these radios are authorized. A list of recommended antennas is
listed in Antenna/Transmission System on page 27.
United States Compliance
The EX-5r operates under FCC Rule Parts 15.247 and/or 15.407 as a license-exempt device. The
EX-4.9i operates under FCC Rule Part 90 as a licensed device. All of these devices must be
professionally installed. It may only be used as a point-to-point transmission device for fixed or
temporary-fixed (non-mobile) installations. The device is subject to the following restrictions:
