Quattro (DP240) vibration and noise data acquisition analyzer

The Quattro (DP240) vibration and noise data acquisition analyzer includes 4 input channels, 2 output channels, and 1 speed channel, fully meeting most engineering tests.

The Quattro (DP240) provides a USB 2.0 interface that can be directly connected to a PC or laptop, and is fully powered through a bus. These features make it highly portable and durable. The real-time analysis capability from DC to 93kHz (204.8 kHz sampling rate) makes it a dream device for NVH engineers. Now, you only need to install the software, connect it to your personal computer with a USB cable, and start measuring and analyzing easily.

Record and analyze data in various environments

The Quattro (DP240) has a compact structure, beautiful design, and the ability to simultaneously record data at a sampling rate of 204.8 kHz across all channels, making it suitable for recording data in airborne, vehicular, and industrial environments. Its weight of less than a pound makes it the best platform for mobile testing.
