Datamate S-Tek RF attenuation measurements (10kHz to 400MHz @ >30dBs RF attenuation) are performed in general accordance with MIL STD 1377 (1971) Screened Cable / Connector Method. Please note that this test was performed with the S-Tek Datamate correctly terminated to a heavy-weight Braided Screened Cable. Overall RF screening performance of any screened cable assembly is reliant upon the connector, cable, and the termination.
