Hello everybody,

We are trying to measure some USB signals on our PCB.
The system is very complex so we would like to understand if our signals are still good enough.
For example we are measuring a differential USB signal from an output port of a transceiver..both near the tx and far the tx (on the connector)...
We have a DSO 90804A so I want to know where can I find the USB mask ? Is it available or I need to install the USB 2.0 compliance test ?

Thanks to everybody
