“`html
The product, manufactured by National Instruments, comes with several part numbers including 782259-01, 781443-01, 782258-01, and 782257-01. This device is equipped with 32 single-ended or 16 differential analog input channels, making it versatile for various data acquisition tasks.
It boasts a maximum sample rate of 2.00 MS/s for single-channel operations and 1.00 MS/s for multichannel tasks, ensuring efficient data processing speeds. The minimum and maximum input values are ±0.1 V and ±10 V respectively, providing a wide range of signal compatibility.
The input resistance is 10 GΩ when in ON mode and drops to 820 Ω in OFF mode. Additionally, it features a bias current of ±100 pA. The settling times range from 1 µs to 2 µs for an accuracy of ±60 ppm, and 1.5 µs to 8 µs for ±15 ppm of step, ensuring precise measurements.
It is designed with overvoltage protection of ±25 V, safeguarding the device from unexpected power surges. The device also includes 4 output channels, with a DAC resolution and output channel monotonicity of 16-bits. The update rates vary from 2.86 MS/s to 1.25 MS/s, adapting to different output needs.
For the BNC model, the weight is 15 oz, and the dimensions are 8.0 x 7.3 x 2.7 in. The mass termination model is significantly lighter at 2.2 oz, catering to different installation requirements.
