Measuring device for measuring signals and data handling method

A measuring device for measuring signals, the measuring device comprising:

• a measurement interface for measuring signals with probe;
• a measurement processor configured to process the signals measured with the probe;
• a data memory configured to store device data for the measuring device,
• a data interface connected to the data memory and configured to read the device data from the data memory and output at least a part of the read device data to an external memory device in a storage mode and to read device data from the external memory device and store the read device data in the data memory in a recovery mode, and
• an identification interface configured to read identification data from a user identification token, wherein the identification token comprises an NFC/RFID tag,
• wherein the device data comprises a full memory image of the measuring device and state information of the measuring device, which resembles the momentary state of the measurement device when the device data is recorded, wherein the state information of the measuring device comprise register values of the measurement processor and content of a memory of the measurement processor,
• wherein the device data comprises measurement data, and the measurement data refers to data which is acquired or generated during a measurement by the measurement device,
• wherein the external memory device is a removable mobile memory device,
• wherein the data interface is configured to store multiple sets of device data on the external memory device in parallel, and
• wherein the data interface is configured to name each set of device data individually when outputting the device data and select a specific directory or file name for each set of device data based on the identification data read from the NFC/RFID tag of the user identification token by the identification interface.
