Overview
The USB-1202 Series is a high‑precision USB data acquisition system engineered for demanding measurement applications. It delivers high DC accuracy of 270 ppm and AI flatness up to 0.004 dB, with outstanding dynamic performance: 120 dBc SFDR, -118 dBc THD, and -109 dBc THD+n. Onboard oversampling technology enhances effective resolution and reduces system noise.
It provides 4‑channel 24‑bit synchronous acquisition, with sampling rates up to 256 kS/s (1202-P7) and 25.6 kS/s (1202-P3). Four voltage ranges (±0.32 V, ±1.25 V, ±5 V, ±12 V), integrated antialiasing filters, software-configurable AC/DC coupling (0.5 Hz AC cutoff), and 4 mA IEPE excitation per channel are included. The module also features 4 lines of independently controlled DIO and supports digital and software triggers.
Housed in an ultra‑compact, bus‑powered USB form factor, it is ideal for precision sensing, vibration analysis, acoustic measurement, sensor signal acquisition, portable test, and laboratory measurement applications.
