A multichannel sensor unit includes: a multichannel sensor detecting at least one physical variable and outputting sensor data representing the detected physical variable; a main memory storing the sensor data of at least two sensor channels; and at least one additional memory. Instantaneous sensor data are stored in response to a trigger signal in the main memory. The sensor unit outputs first sensor data of a first sensor channel, which are stored in the main memory, in response to a first read command, and stores the additional sensor data in the at least one additional memory in response to the first read command. The sensor unit outputs the sensor data stored in the at least one additional memory in response to a second read command, such that the sensor unit outputs the sensor data from the main memory and the additional memory asynchronously. |
