¹The average streaming rate defines the amount of data which can be transferred on the fly to the PC per second. If the trace-port rate is below that streaming rate in average, a practically infinite recording time is possible. The peak-rate is possible temporarily and is compensated by the internal memory of the PowerTrace extension.

²We specify here the speed of the serial link. The maximum speed for the transferred payload is usually smaller due to line encoding, e.g. 80 % with 8b/10b encoding.

³ Requires serial preprocessor. For serial tracing we recommend PowerTrace Serial.

⁴The streaming rate defines the amount of data which can be transferred on the fly to the PC per second. If the trace-port rate is below the streaming rate in average, a practically infinite recording time is possible.

⁵CombiProbe 2 works with PowerDebug E50, X50, X51, E40, PRO, USB 3, II. Not supported are PowerDebug Ethernet, USB, or USB 2.

⁶PowerTrace extensions work with PowerDebug X50, X51, PRO, II.
