The TETRA Energy Economy Mode (EEM) option is now available for Aeroflex's 3900 Series of analog and digital radio test sets. The new TETRA EEM option enables more flexible battery-life testing for developers, operators, and users of TETRA handheld mobile radios who need to prove their design and quantify or qualify battery-life performance claims.

The option will allow Aeroflex 3900 Series users to configure battery-test scenarios that simulate particular operational conditions. In addition, it will provide the testing flexibility to characterise the expected battery-life performance when using the device on the network.
