Description
The National Instruments USB-5684 is a high-performance tool designed for accurate average power measurements of radio frequency (RF) signals. It excels in various industrial applications thanks to its key features:
- Wide Dynamic Range and High Accuracy: The USB-5684 boasts a wide dynamic range, likely exceeding 80 dB based on similar NI products [1]. This allows it to measure a broad spectrum of power levels with high accuracy. National Instruments mentions a typical accuracy of ±0.13 dB at lower power levels [1].
- True RMS Measurements: It goes beyond basic average power by utilizing True RMS (Root Mean Square) technology. This ensures accurate readings even for complex waveforms containing harmonics or distortions, commonly encountered in RF signals.
- Frequency Range: While the exact range isn’t publicly available without consulting a datasheet, the USB-5684 likely caters to a significant portion of the RF spectrum, potentially ranging from 10 MHz up to 18 GHz or higher [2]. This makes it suitable for various modern RF applications.
- Multiple Signal Types: It can handle continuous wave (CW), multitone, and digitally modulated signals, providing versatility for different RF communication standards or signal sources
- Triggering Options: The USB-5684 offers internal and external triggering options for capturing specific signal events, important for analyzing signal behavior or synchronization purposes
- Compact and Bus-Powered Design: The USB-5684 leverages a compact design and draws power directly from the USB connection, eliminating the need for a bulky external power supply. This enhances portability and simplifies setup for field measurements or space-constrained environments.
Specifications
- Function: High-frequency analog data acquisition module for measuring average power of RF signals (specifically designed for industrial applications)
