Introduction
The BERTScope SATA Tee facilitates SATA compliance tests by switching
the Product-under-test (PUT) I/O lines between a protocol analyzer and the

UT Transmit (Tx) outputs are split with an asymmetrical splitter which
The D
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”
osition, the protocol legs of the combiner are terminated into 50 Ω.

1. Turn the BERTSc
ope pattern generator outputs off and switch the Tee to
the Protocol position.
2. Use the protoc
ol generator to send the desired BIST command to the PUT
and verify a successful transaction.
3. Turn on the BERTScope pattern generator outputs to a voltage level higher
than the protocol generator outputs (such as, 1000 mV
on each leg of the
p-p
differential signal).
This may require experimentation to determine the required voltage
depending on the output voltage of the protocol generator. This s tep causes
the BERTScope PG output signal to be the dominant signal source, swamping
the protocol generator output signal.
4. Switch the Tee to the BERTScope position.
5. Lower the BERTScope PG outputs to the proper voltage level and then
proceed with the testing.
The state of the SATA Tee switch can also be controlled electrically, enabling
its use with automated or semi-automated testing systems. Remote control is
ssible through the CONTROL connector.

The Control signal switches the SATA Tee from the normal BERTScope testing
path to the Protocol connected path. The signal is pulled up internally to +3.3
volts. Switching to the Protocol connected path is performed by grounding this
pin, either by shorting to Pin 2 or 6, or with an external open collector or open
drain logic gate.

Performance characterization
The BERTScope SATA Tee functionality was verified using a U-Link Drivemaster
protocol analyzer system to ensure that the PUT could be programmed when the
switch was in the “protocol” position. It was then characterized for insertion loss
and return loss using a Rohde and Schwarz ZVA-24 Vector Network Analyzer.
