radio link endpoints are distant from one another. A back-to-back bench test and pre-configuration will
provide confidence that the radio link is operational and properly configured prior to installation, so
that if troubleshooting is necessary, the radio hardware and configuration settings are eliminated from
the troubleshooting process. Verify the following in the back-to-back testing:
• Confirm that the radio system is generally operational
– Radios power-up with planned power and wiring solutions
– RF link connects in both directions
– Traffic passes across the link
• Configure connected equipment and cabling
– Test Ethernet (CAT5) cabling, and/or TDM cabling, any auxiliary connector cabling and
configure all interfaces
– Configure IP settings for configuration and management
– Configure passwords and security modes
– Become familiar with the configuration and management interfaces through the Exalt GUI
interface
– Configure radio parameters, including installing any optional software license keys and
configuring features controlled by license keys
– Set transmitter output power to engineered or allowed level (see
RF Output Power Setting)
– Set operating center frequency
– Set occupied channel bandwidth and Mode (modulation) setting
• Make detailed radio performance measurements
– Measure transmitter output power
– Measure receiver threshold performance
– 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.
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
Note: See Back-to-back Bench Testing for detailed instructions.
