Description
The National Instruments USB-6341 is a versatile data acquisition device designed for a wide range of applications. This model comes with various part numbers, including 781438-01, 782251-01, 782250-01, and 782254-01, each corresponding to different connector types such as Screw Terminal (781438-01) and BNC (782251-01).
It features 16 single-ended or 8 differential analog input channels, providing flexibility in handling various types of signals. The device boasts a 16-bit ADC resolution, ensuring high accuracy and precision in measurements. Additionally, it offers 2 analog output channels for signal generation, with a maximum sample rate of 500 kS/s, enabling efficient data transfer and processing.
The USB-6341 is designed for precise timing and synchronization, with a timing resolution of 10 ns and timing accuracy of 50 ppm. Its input coupling is DC, accommodating a range of input ranges (±0.2 V, ±1 V, ±5 V, ±10 V) and supporting a working voltage of ±11 V. The device also features an impressive Common Mode Rejection Ratio (CMRR) of 100 dB.
With an input impedance of 10 GΩ (On) and 1,200 Ω (Off), and a parallel input impedance of 100 pF, the USB-6341 ensures minimal loading on the measured signal. Users are recommended to allow a 15-minute warm-up time for optimal performance. To maintain accuracy, calibration is recommended at least once every 2 years.
The device also features a low input bias current of ±100 pA and excellent isolation between channels, with a crosstalk frequency of 100 kHz and adjacent channel crosstalk of -75 dB. This level of performance makes the National Instruments USB-6341 an ideal choice for demanding data acquisition tasks.
