Description
The National Instruments USB-6351 X Series (DAQ) you described is a high-performance multifunction data acquisition device that offers significant advantages for applications requiring fast analog signal capture. Here’s a breakdown of its key features and how it compares to the previously discussed USB-6341:
Superior Analog Input Sampling Rate: The most striking difference is the significantly faster analog input sampling rate. The USB-6351 boasts a maximum sampling rate of 1.25 MS/s (megaSamples per second) per channel. This allows it to capture much faster changing signals compared to the USB-6341’s 500 kS/s rate.
Multi-Channel Sampling Trade-Off: While excelling in single-channel sampling, the USB-6351 has a slightly lower aggregate sampling rate of 1 MS/s when measuring on multiple channels simultaneously (compared to the USB-6341’s 500 kS/s). This means there’s a trade-off between the speed of individual channel acquisition and the ability to acquire data from multiple channels at once.
Maintains Analog Input Resolution and Range: The USB-6351 retains the good 16-bit resolution for accurate signal representation and a +/- 10 V input range for compatibility with various sensors.
Analog Output Capabilities: Similar to the USB-6341, it offers 2 analog output channels with a high 2.86 MS/s sampling rate, 16-bit resolution, and a +/- 10 V output range. This allows for generation of high-frequency control signals.
Digital I/O: It maintains the same 24 digital I/O lines with 8 hardware-timed lines at 10 MHz for precise digital signal timing.
Multifunction Functionality: Like the USB-6341, the USB-6351 is a multifunction device suitable for applications involving both analog and digital signals.
