More info

The USB-2405 is a 24-bit high-performance dynamic signal acquisition USB module equipped with 4 analog input channels providing simultaneous sampling at up to 128 kS/s per channel. The USB-2405 also features software-selectable AC or DC coupling input configuration and built-in high precision 2 mA excitation current to measure integrated electronic piezoelectric (IEPE) sensors such as accelerometers and microphones.

The USB-2405 delivers high precision, DC and dynamic measurement performance with very low temperature drift. The onboard 24-bit Sigma-Delta ADC supports anti-aliasing filtering, suppressing modulator and signal out-of-band noise and providing usable signal bandwidth of the Nyquist rate, making it ideal for high dynamic range signal measurement in vibration and acoustic applications.

The USB-2405 supports digital and analog trigger sources and flexible trigger modes, including post, delay, middle, gated, and pre-triggering for efficient data acquisition with no need for post-processing. The USB-2405 is USB bus-powered and equipped with BNC connectors and removable spring terminals for easy device connectivity.

Why ADLINK USB-2405?

The ADLINK USB-2405 is a dynamic signal acquisition module featuring high accuracy and excellent dynamic performance, directly acquiring signals from the IEPE accelerometers and microphones commonly used in vibration and acoustic applications without extra signal conditioning. The included time-frequency analysis software, Visual Signal DAQ Express, simplifies acquisition and analysis of noise and vibration signals for instant results, in an easy-to-use application with interactive user interface.


Combining high accuracy, excellent performance, and powerful analysis application Visual Signal DAQ Express, the USB-2405 is the best choice for a portable time-frequency spectrum analyzer for machine diagnostics and failure prevention, research, and portable field measurement, and especially for handheld meter and benchtop analysis users who seek improved performance and functionality while conserving costs while maintaining basic analysis capability, such that projects are expedited easily and efficiently.


ADLINK Solution


Shortened Development Time

The Visual Signal DAQ Express's visualization user interface help you acquire and analyze the noise and vibration signal without any programming, which can minimize the development time of a new project.


Development Time



The ADLINK USB-2405 provides analysis functions similar to known sound and vibration analysis software, which can conserve development resources.


Cost Effective


IEPE Input

For applications utilizing sensors such as accelerometers or microphones, the USB-2405 provides an excitation current source.

The excitation current is 2 mA for the IEPE sensors, with DC voltage offset generated because of the excitation current and sensor
impedance. When enabling IEPE current sources, the USB-2405 automatically sets input configuration to AC coupling.
