For a Host Side Application
Configure the
TUSB217A
to the desired BOOST setting.
Power on (or toggle the RSTN pin if already powered on) the
TUSB217A
.
Using SMA cables, connect the oscilloscope and the USB-IF host-side test fixture to the
TUSB217A
.
Enable the host to transmit USB TEST_PACKET.
Execute the oscilloscope USB compliance software.
Repeat the above steps in order to retest
TUSB217A
with a different BOOST setting (must reset to change).
