Back-to-Back Bench Test and Configuration
Every Exalt digital microwave radio goes through extensive quality testing and
performance evaluation over the full operating temperature range prior to shipment.
However, before installation, it is strongly advised to perform several tests and tasks that
are much more difficult to perform once the 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 T1/E1 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
¶ Set transmitter output power to engineered or allowed level (see RF Output Power
Setting on page 25)
¶ Set operating center frequency
¶ Set link distance, occupied channel bandwidth, and frame length
• 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.
