National Instruments 779748-01 PXI Sound and Vibration Module
The National Instruments 779748-01 is a 16-input AC-coupled PXI Sound and Vibration Module. It is designed for high-channel-count applications and is also identified as PXI-4496. It features 24-bit delta-sigma analog-to-digital converters (ADC) which offers high precision for measurements involving microphones, accelerometers, and other transducers with extensive dynamic ranges. Each input channel supports simultaneous sampling to ensure accuracy across all channels.
The 779748-01 supports a maximum sample rate of 204.8 kS/s with a resolution of ≤181.9 μS/s. The module includes built-in antialiasing filters that adjust automatically to the sampling rate, along with software-selectable input gains up to 20 dB. The allowable input voltage ranges from ±1 V to ±10 V. The IEPE signal conditioning is software-selectable which supports 0 or 4 mA constant current. This NI module includes robust overvoltage protection: ±30 V for the positive terminal and ±5 V for the negative terminal. The maximum working voltage of the unit is ±10 V and ±1 V for positive and negative terminals. The input impedance is 10 MΩ between positive and negative inputs which ensure minimal loading on the measured signal. The FIFO buffer size is 4,095 samples.
Analog and digital triggers on the 779748-01 module offer flexible triggering options. Analog triggers support start or reference triggers from any AI source with programmable levels and slopes. Digital triggers are compatible with transistor-transistor logic (TTL) signals and can be sourced from PFI0 or PXI trigger lines. This module’s compatibility with PXI and PXI Express buses ensures seamless integration into existing systems.
Environmental specifications include an operating temperature range from 0 °C to 55 °C and a storage range from -20 °C to 70 °C. The NI 779748-01 sound and vibration module can operate up to 2,000 meters in altitude and withstands operational shocks up to 30 g peak. Vibration tolerance ranges from 5 Hz to 500 Hz at 0.3 g during operation, and up to 2.4 g in non-operating conditions. This module meets stringent safety and electromagnetic compatibility standards that include IEC 61010-1, EN 61010-1, UL 61010-1, CSA 61010-1, and various EMC standards for Class A emissions and basic immunity.
