About Beta


Quick, Easy Testing: 
One-Person Operation

Now one person can easily detect shorts, opens, crossovers and shorts-to-shield on the bus and stubs, all from the easily accessible Line Replaceable Unit (LRU) ends of the stub cables.

Cordless Battery Powered

Uses a supplied 9V rechargeable battery, or in an emergency a standard 9V battery can be used. Longer battery life is made possible by the press-to-test feature of the tester so the main unit only draws current when a button is pushed.

Easy-to-Read Status Display

  • LCD digital read out for resistance, insertion and return loss
  • LED pass/fail indicators




The DBT300 is shipped in its own carrying case and consists of an NH16746MA main unit, an NH16746R remote unit, NH14017BC battery chargers for the main and remote units and two 3 foot cable assemblies with PL73 connectors attached. It also includes 9V batteries.




The tester is provided with two 3-foot MIL-STD-17/176-00002 cables with a PL73 push-on type connector on each end. Consult the factory for custom cables or adapters.
