RTBx

RTBx™ provides a target-independent, long duration, high-data rate logger for recording time-stamped data from embedded real-time applications. The RTBx data logger provides an excellent way of collecting trace data for use by RVS.

Connected to an output port of embedded hardware, RTBx logs and timestamps data values that appear. The use of an output port for generating trace data minimizes the instrumentation overhead of a real-time application.

Two variants of the RTBx are available:

  • RTBx1210
    Capture data up to 16 bits wide
  • RTBx1221
    Capture data at higher rates and up to 32 bits wide
