AEA Technology and ITT Exelis have announced that they have been awarded a joint multi-year contract to provide the US Navy with a Hand-Held Aircraft Wiring Tester (HAWT), enhancing aircraft maintenance procedures for the navy. The companies announced the contract, issued late in 2011, 24 July 2012.

The HAWT's main component is a battery powered hand-held Step TDR based on AEA Technology's new E20/20 Step TDR and modified to meet the US Navy's requirements. The entire assembly includes a carrying case various test leads, AC adapter, belt case and the new ETDR PC Vision software all of which must meet the navy's MilStd specifications for shipboard and aircraft use. With the HAWT, aircraft maintenance personnel will have a highly capable new instrument to isolate wiring fault within +/- 1 inch with resolution to 0.5 inch.

AEA Technology's 20/20 Step TDR has been on the market since 2004 and is now being replaced by an enhanced version - the E20/20 Step TDR. These TDRs can measure any type of coax, twisted pair, single pairs in a harness and other cables and other applications such as soil moisture content. They have no dead zone on any range setting and are loaded with features to help evaluate cable parameters.

MicroFault locating provides two methods of finding small impedance variations from coax kinks or other mishandling that are hard to spot on a normal impedance trace. Both the HAWT and E20/20 TDRs have a user modifiable cable list that can be updated in the TDR or by using ETDR PC Vision software supplied with the TDR. Unlimited cable lists can be stored on the PC. ETDR PC Vision can also upload current or stored TDR traces and save, print or export their data points in multiple file formats.
