Overview

The USB-XM1636 is a high-performance data acquisition card suitable for measurement applications requiring medium to low speed and high precision. The USB-XM1636 features 32 analog inputs (configurable as single-ended or differential), 4 channels of 16-bit DA output, 8 digital input (DI) channels, 8 digital output (DO) channels, and two 24-bit frequency measurement/counters. It includes onboard programmable gain amplifiers (×1, ×2, ×4, ×8), allowing software configuration of different gain settings per channel. The device supports external clocking and external triggering, meeting a wide range of measurement requirements. Logic control is implemented using a Field-Programmable Gate Array (FPGA) to enhance reliability. Additionally, digital ground (GND) and analog ground (AGND) are separated with single-point grounding to eliminate loop interference.

The USB-XM1636 uses the CYPRESS CY68013A as its USB controller chip. This board is a high-speed, high-precision USB 2.0 bus data acquisition card that supports hot-plugging and plug-and-play functionality. Designed with an FPGA for improved reliability.

The product ships with drivers, dynamic link libraries (DLLs), programming guides (including demo programs) for Win10/8/7/Vista/XP, example acquisition programs in VB, VC, and LABVIEW, and comes with a two-year warranty.

Product Applications

The USB-XM1636 is a USB 2.0 bus-based data acquisition card that connects directly to a computer's USB port, enabling data acquisition, waveform analysis, and processing systems for laboratories, product quality testing centers, and other fields. It can also be used to build industrial process monitoring systems. Typical application areas include:

Signal acquisition

Electronic product quality inspection

IO control

Square wave frequency measurement

Pulse counting
