Astro-Med DASH 8HF-HS High Frequency High Security Data Recorder

The Dash 8HF-HS is a powerful, compact and portable data acquisition recorder engineered specifically for capturing high frequency data and transient signals. It provides isolated inputs with sample rates up to 2 MHz and a bandwidth of 200 KHz per channel. The Dash 8HF-HS is the ideal system to give you an accurate record of your high speed data.

The Dash 8HF-HS offers intelligent, versatile data capture. Eight isolated analog inputs and eight event inputs can be streamed directly to a removable 250 GByte hard drive. Sample rates can be varied from 2 MHz per channel to 100 Hz per channel. You can even capture trend data at slower sample rates while embedding higher sample rate scope capture at the same time!
