SATA Tee

The BERTScope SATA Tee facilitates SATA compliance tests by switching the product under test (PUT) I/O lines between a protocol analyzer and the BERTScope. This allows the Device Under Test (DUT) to be set to the proper Built In Self Test (BIST) mode for testing without disconnecting the SATA connector.

The PUT Transmit (Tx) outputs are split with an asymmetrical splitter which sends a small fraction of the signal through an amplifier to the protocol Receiver (Rx) inputs. The majority of the signal is sent to the BERTScope CR inputs. This preserves the signal to noise ratio of the PUT Tx signal at the BERTScope inputs.

The BERTScope Tx outputs are connected to one side of a symmetrical 6 dB power combiner. The protocol generator Tx outputs are amplified and connected via a switch to the other leg of the combiner. The common legs of the combiners are connected to the PUT Rx inputs. When the switch is set to the ‘BERTScope’ position, the protocol legs of the combiner are terminated into 50 Ω.
