Appendix B – Back-to-back Bench Testing
B-1 Introduction
Back-to-back bench testing is used to test the radio before installation, pre-configure the radio
and connected equipment before installation, or in the troubleshooting process to identify if the
radio hardware is the source of a system issue. It is a critical process, and often required or
highly desirable for any installation or troubleshooting exercise. This section describes how to
properly configure the radio hardware and accessories for a proper back-to-back bench test.
For radio testing, there are two types of back-to-back configurations:
-
Basic test (test general operation)
-
Specification performance verification
B-2 Basic
Test
The basic test is a simple test of radio functionality. It verifies that the radios are configured
properly to communicate to one another, and verifies general radio performance to be
operational.
For the basic test, the following items are needed:
-
Radio pair
-
Powering source
-
RF interconnect cable(s) (any length – short is best)
-
Fixed or variable attenuation, between 60 and 90dB at 5800 MHz (note:
attenuation for basic test does not to be calibrated or precise)
-
Computer/Terminal with either Serial or Ethernet port (helpful, but not necessary)
If no computer is available, you will need the temporary hardware
configuration key
Connect the items as follows:
-
Connect attenuation and (known-good) RF cable(s) between radio pair, as shown
in Figure B-1.
-
Configure one radio to be Radio A, the other to be Radio B
-
Power on radio pair
