7 16/08/016 REF.: RADDETATCH010 7/ ELECTRICAL MEASUREMENTS The parameters to be measured at room temperature are scheduled in. Unless otherwise specified, the measurements shall be performed at T amb = + ± 3 C. The measurement shall be performed with five points of frequency: 4GHz 8GHz 1.4 GHz 18GHz and GHz. 6. CONNECTORS REPEATABILTY: The test shall be performed according to the following conditions: Attenuation shall be recorded at three points of frequency : 4GHz 1.4GHz and GHz Ten complete engagements and separations shall be performed, both end separately Attenuators shall be rotated through the full 360 with an increment of approximately 36 for each engagement. Attenuation drift value : ±0.05 db Side thrust is not permitted during the test Cleaning of connetcors or reshaping of contacts was not permitted during the sequence 7. OPERATING LIFE 7.1. PARAMETER DRIFT VALUES The parameter drift values applicable to burnin are specified in Table 3 of this specification. Unless otherwise stated, measurements shall be perfromed at T amb = + ± 3 C. The parameter drift value ( ) applicable to the parameters scheduled, shall not be exceeded. In additional to these drift value requirements for a given parameter, the appropriate limit value specified in shall not be exceeded. 7.. CONDITIONS FOR OPERATING LIFE The condition for Operating life are given in Table 4. After test, a visual inspection shall be performed and no damage shall be appeared.

The dissipated power at DC or in frequency is the same.

8 16/08/016 REF.: RADDETATCH010 8/ 13 Test mounting for Operating life: The DUT (attenuator under test) shall be mounted directly on the Hybrid coupler without SR cable between the coupler and the DUT.
