Description
The USB-6341 is a PC-based Multifunction DAQ unit, distinguished by its part numbers 781438-01, 782251-01, 782250-01, and 782254-01. This device is designed to facilitate a wide range of data acquisition tasks.
It features 16 single-ended or 8 differential analog input channels, with an ADC resolution of 16 bits, ensuring precise data capture. For output, the USB-6341 offers 2 analog output channels, allowing for efficient data output to external devices.
The maximum sample rate achievable by this DAQ unit is 500 kS/s, which is complemented by a timing resolution of 10 ns and a timing accuracy of 50 ppm. This high level of precision in timing ensures that the data captured is both accurate and reliable.
For input coupling, the device employs a DC method, and it supports input ranges of ±0.2 V, ±1 V, ±5 V, and ±10 V, with a working voltage of ±11 V. Such versatility in input ranges makes the USB-6341 suitable for a broad spectrum of applications.
The unit boasts a Common Mode Rejection Ratio (CMRR) of 100 dB and offers an input impedance of 10 GΩ when on and 1,200 Ω when off, parallel with 100 pF. This high input impedance ensures minimal interference with the circuit being measured, leading to more accurate data acquisition.
