摘要： This disclosure provides systems, methods, and apparatus for implementing multiple test and measurement devices into a single multi-instrument device (102). The device can include at least one field programmable gate array, FPGA (112), that allows partial reconfiguration. One or more dynamic reconfigurable portions of the FPGA can be configured to function as one or more test and measurement devices. The device can provide outputs of each of the test and measurement instruments to a client device, which can display the outputs to a user. The device can be reconfigured by loading bitstreams (122,136) associated with the desired test and measurement device. The bitstreams can be loaded from the client device (104), a server (106), or from a memory storage unit (114) of the device itself.

摘要： A device for dynamic signal generation and analysis, which combines an arbitrary waveform generator AWG (3) with a digital signal analysis unit DSAU (23). The two units are interfaced by means of a synchronization unit SU (30), which enables a flexible scheme for controlling how the playback of the waveforms is started as well as synchronizing the recording of the results of the digital signal analysis unit synchronously to specific generated waveforms. The various units of the device are synchronous circuits clocked by a common system clock signal. At least one common numerically controlled oscillator NCO (40) is provided for the arbitrary waveform generator AWG (3) and the digital signal analysis unit DSAU (23).

摘要： 본 발명은 3상 전력의 전압-전류측정기에 사용되는 전류측정 어댑터장치에 대한 것으로서, 더욱 상세하게는 전압-전류측정기를 사용하여 전류 측정시 복수 단자의 결선 오류를 방지할 수 있는 전류측정 어댑터장치에 대한 것이다. 본 발명의 일 측면에 따른 3상 전력의 전압-전류측정기용 전류측정 어댑터장치는 2개의 R단자, 2개의 S단자, 2개의 T단자가 형성된 전압측정단자와, Ri단자, Ro단자, Si단자, So단자, Ti단자. To단자가 형성된 전류측정단자를 구비하는 3상 전력의 전압-전류측정기에 있어서, 상기 2개의 R단자를 서로 연통시키고, 상기 2개의 S단자를 서로 연통시키고, 상기 2개의 T단자를 서로 연통시키고, 어느 한 상기 R단자와 어느 한 상기 S단자와 어느 한 상기 T단자만 외부에서 접속할 수 있게 상기 전압측정단자에 탈착할 수 있게 장착될 수 있다. 본 발명에 의하면, 전류측정 어댑터장치를 전압-전류측정기의 장착하면 작업자는 전압측정단자 및 전류측정단자를 별도로 결선하지 않고 전류를 측정할 수 있다. 그래서 전압측정단자 및 전류측정단자의 결선을 잘못하여 발생될 수 있는 오류를 방지할 수 있다.
