USB 6
Agilent Infiniium 9000 Series Oscilloscope Evaluation Guide 39
Set up serial decode:
16 Choose Setup>Serial Decode....
17 In the Serial Decode dialog, select:
Then, click Auto Setup and Close.
Auto Setup sets the sample rate, memory depth, measurement
thresholds, trigger levels, and holdoff to correctly decode the
specified protocol.
You are now viewing USB full speed traffic. To make the protocol
decode more interesting, let’s watch traffic that is more varied.
18 Copy any large file (a 100M file generates about 2 minutes of
traffic works well) from a thumb drive (+full speed hub) plugged
into the demo board to the Infiniium 9000 Series desktop (or vice
versa).
Note: Most new thumb drives are high speed USB. To convert the
traffic into full speed, use a full speed hub.
19 Press [Single] to capture a single trace.
