N5413B/N5413C DDR2 Compliance App: Incorrect Connection Diagram?

I'm using scope MSOS604A with the DDR2 compliance app, and it seems that the connect diagrams are incorrect in a couple places.

 

  1. To measure tDS for the Data Mask signal, a probe would need to be connected to the DM pin. That's not shown in the Connection Diagram.
  2. To measure tDS1(derate), I believe the probe connected to DQS would need to be singled-ended, but the connection diagram still shows DQS and DQS connected to the differential probe together. The connection diagram does show a single-ended probe on DQS for the tDS1(base) measurement.

 

Both of these issues apply to multiple measurements in same group of tests.
