Real-time Data Recorders

HBM, Inc. has added real time data calculation capabilities to its 1kV card. A new isolated 1kV data acquisition card let the data recorders perform real time calculations on the fly, while allowing users to view results immediately. In contrast, other devices require the use of post-processing software to view analysis results later rather than in real-time.

The new card also lets Genesis High Speed recorders calculate more precise results. Many data recorders provide an average value for a block of data over a certain time period. The 1kV card, instead, provides values per half cycle at sampling rates of up to 2 million samples/second at voltages up to + 1000 V. Users can therefore see dynamic data such as currents and voltages produced when an electric motor is accelerated, for example. This capability helps engineers more easily meet design goals for optimization and efficiency. The system’s sampling rate can be automatically switched following a trigger event in the real time calculation channels. Maximum sampling rates are therefore then only used for particularly critical measurement events. This results in smaller data files, so that testing becomes significantly more efficient.
