We have the Beagle 5000 v2 Protocol Analyzer - Standard Edition and we have used it for triggering for USB 3.0 traffic.  For example, we have set  it up with the  trigger to capture an ACK (acknowledgement) packet,  but we don't see how to set it up to trigger on NRDY (not ready).  Is that possible with the standard edition, or do we need get an upgrade for Complex Triggering?

Thanks for your question! You can definitely set up complex triggers with the Beagle 5000 V2 analyzer, and it is very easy to do that with the Data Center Software. Here are the steps:

1. 1. 1. At the Menu Bar (at the top), select Analyzer and then select Device Settings.
      2. When the Device Settings dialog opens, select the USB tab and then click the Addition Settings button.

      3. In the Additional Settings dialog that opens up, select the USB 3.0 Matching tab, click the Complex button and make sure the Enabled box is checked.
      4. Click New Match Action and from the drop menu select DS Data Match (DS is downstream, and US is upstream).

      5. In the DS Data Match Configuration dialog, for Packet Type select Header Packet. The dialog now shows you the options that you can use for a complex match.  Here, you can enter the desired binary pattern by replacing the X characters with "1" or "0". To make it easier, you can select Type options that will enter the important data patterns for you.
      6. Click Type and select Transaction Packet from the drop menu. The dialog box becomes more detailed, as shown.
      7. Click SubType and select NRDY from the drop menu.
      8. If desired, you can further specialize the pattern for your trigger by replacing "X" with "1" or "0".
