Astro-Med Dash 20HF

The DASH 20HF is engineered for long term capture of high frequency data and transient signals.

It supports recording up to 20 analog channels to an internal 250 GB hard drive at sample rates of up to 500 kHz and with a bandwidth of 100 kHz per channel.  Applications range from transient capture to remote troubleshooting in the aerospace, automotive, electric utility, pulp and paper, metal manufacturing, medical, and other industrial fields.

Tthe Dash 20HF is portable and rugged enough to handle any environment. The user has real-time display and analysis of data. High frequency data captures can be saved directly to hard drive for later review and analysis.

The recorder contains four 250 Vrms isolated inputs, ideal for monitoring high voltage or power signals, and sixteen 35 Vrms differential channels for monitoring low level signals or inputs from sensors, signal conditioners and other devices. Each channel input can be independently configured and has a dedicated 16 bit A/D converter to assure the most accurate measurement.  The versatile digital signal processing of the Dash 20HF provides a wide variety of data capture filtering capabilities, including low-pass, high-pass, band-pass, RMS and notch filtering. Frequency counter inputs are also included.
