The PXI acquisition equipment adopts NI PXI-1045 18 slot chassis, and the NI PXI-8187 main controller is the main controller. The acquisition cards are NI PXI 6652, 6602, 4472B, of which:
The PXI 6652 clock synchronization module uses the SMB interface provided by NI to connect with the 10M PPS output terminal of the GPS receiver, receives the 10M PPS clock signal, divides the frequency of the clock signal, provides the divided frequency clock signal to the PXI chassis backplane, and provides the high-speed synchronous acquisition card PXI 4472B as the sampling clock frequency.
The PXI-6602 counter is connected to the 1 PPS output terminal of the GPS receiver with a wiring segment sub board. It needs to be connected to two input ports at the same time to receive 1 PPS signals. After the first input terminal receives the signal, it counts according to 1 PPS frequency and sets the acquisition time. When the acquisition start time is reached, PXI-6602 provides a trigger signal to trigger PXI-4472B to start the acquisition; The 1 PPS frequency pulse of the second input provides a phase synchronization trigger for 4472B.
The standard 232 serial port of the PXI-8187 controller is connected to the absolute time output terminal of the GPS receiver, receives the absolute time information provided by the GPS receiver, and calculates the time interval of each sampling point+the absolute time of trigger start to obtain the absolute time tag of the sampling point.
