The PXI-6251 is a multifunctional I/O module with analog I/O, associated digital I/O, two 32-bit counters/timers, and analog and digital triggers. The device provides low-cost, reliable DAQ capabilities for a variety of applications ranging from laboratory automation, research, design validation/testing to manufacturing testing.
The PXI-6251 has a 16-channel 16-bit analog acquisition channel, with the acquisition frequency of 1.25MS/s for single channel and 1MS/s for multi-channel. 2 16-bit analog output channels, update speed of 2.8MS/s; 24-channel digital TTL input/output control; 2 pulse input and output; The maximum analog input and output voltage ranges from −10V to +10V.
The programming language of PXI-6251 uses LABVIEW, which is a graphical language for virtual instruments. In the design, LABVIEW8.5 is used to complete the design of PXI module, which is mainly to realize 2 analog voltage waveform output of different frequencies, 1 digital pulse output, multi-channel digital TTL level output, and collect and save signals.
In practical applications, PXI-6251 card can be used in A variety of fields, such as the purpose of calibration is to adjust the test equipment, reduce the error, under normal circumstances, the circuit state and parameters of the amplifier, filter, A/D converter and internal reference source components in the test instrument will deviate from the standard value, and will drift with the change of time and temperature. The calibration process is used to adjust these drifts to improve the accuracy of the test. The calibration principle of PXI-6251 is to compare a known high-precision measurement source with the measured value of PXI-6251, calculate the adjustment value that makes the minimum deviation between the two, and store this value in the EEPROM on the board as a calibration constant, and read the calibration constant from the EEPROM before the test to calibrate the hardware. These processes can be controlled by software. There are two methods for PXI-6251 calibration: one is external calibration, by external input a high-precision stable measurement source to compare with the measured value to obtain the calibration constant.
