A probe includes, a substantially L-shaped cylindrical probe body coupled through a cable to a measuring device and a temperature measuring section connected to the probe body. The printhead module includes a plurality of thermal sensors. The power control commands issued from the base station to the user device will, therefore, reflect this lower estimated channel quality and, as a result, the user device will follow power control commands from the base station in the HSDPA cell. The processor unit can be configured to embed the digital input data and time data as well as the event data as protected raw data into the generated data format such that they can be read and processed only with hardware-specific evaluation software.
