Dash 32HF

The Astro-Med Test & Measurement Product Group, West Warwick, RI, has introduced the Dash 32HF multi-channel, high-frequency data acquisition recorder. Engineered to capture high-frequency data and transient signals, the unit records up to 32 channels to an internal hard drive at sample rates up to 500 kHz, and a bandwidth of 100 KHz per channel. The system contains 32 differential inputs that accept up to ±50 VDC. Filtering capabilities include low-pass, high-pass, band-pass, and notch filtering. It is equipped with a 15" diagonal monitor for touchscreen control and real-time data viewing and analysis. It also includes a dedicated, 250 GByte internal hard drive for capturing data, and a DVD burner for archiving data. Other features include 10/100/1000BaseT Ethernet for data upload, and a USB 2.0 port for archiving to external devices. It operates on 120 or 240 VAC, and includes a capacitive backup for proper shutdown without data corruption if power is lost.
