Description
The NI-9260 is a component of the C Series Analog Output category, identified by part numbers 156758A-02L (BNC), 783466-01 (BNC Version), and 783467-01 (Mini-XLR Version). This module is designed specifically for audio components testing and consumer goods capabilities testing, making it a versatile tool in the audio engineering and manufacturing industry. The NI 9260 comes equipped with both BNC and Mini-XLR connectivity options, accommodating a wide range of audio equipment.
With its 2-channel output, the NI-9260 is capable of delivering audio signals at an update rate of 51.2 thousand samples per second, ensuring high fidelity and precision in audio reproduction. Each channel can output a range of up to 3 Vrms, driven by a 24-bit resolution. This high level of resolution is achieved through the use of a Delta-Sigma type Digital-to-Analog converter, providing users with accurate and detailed audio output.
The module offers robust protection features, including short circuit protection and ±30 V overvoltage protection, safeguarding both the device and connected components from potential damage. The output stage of the BNC version is pseudo-differential, with Audio Output (AO) terminated through a 50 Ohm resistor to ground. In contrast, the Mini-XLR version features a balanced and fully differential output stage, catering to different audio connection standards and preferences.
Additionally, the NI-9260 supports DC output coupling, enhancing its compatibility with various audio testing and playback scenarios. Its accuracy is typically within ±0.6%, with a ±0.05 dB gain error and a ±0.7%, ±30 mV offset error, ensuring reliable and consistent performance in critical audio applications. Despite its advanced capabilities, the module maintains a low power consumption of 0.93 Watts (max), making it an energy-efficient choice for continuous use.
