Settings for the supported Instruments
This section gives a list of default oscilloscope settings that the application uses for supported instruments.
The recommended voltage probe for single-ended signals are the P6245 or P6243 or TDP1500 or TDP3500
or TAP1500 probes and for differential signals is the P6248 or P6330 probe. The next table shows the
oscilloscope settings for Low Speed and Full Speed signals for the supported instruments.

Upstream Setups for Full Speed Signals
You c
an test the Full Speed devices at Tier 6. This testing is also known as legacy testing.
When Full Speed and Low Speed device are High Speed capable, the application uses the signal rate limits
of F
ull Speed/Low Speed devices which a re not High Speed capable t o determine PASS or FAIL.
