The Dash 20HF-HS is a portable data acquisition recorder engineered specifically for capturing multiple channels of high frequency data and transient signals. It provides 20 analog inputs (4 high voltage (250 Vrms) and 16 differential voltage (35 Vrms)) with sample rates up to 500 kHz and a bandwidth of 100 kHz per channel! The Dash 20HF-HS is the ideal system to give you an accurate record of your high speed data along with all of the channels you need in one compact package.

 

High-Speed Data Acquisition
The Dash 20HF-HS offers intelligent, versatile data capture. Twenty analog and eight event inputs can be streamed directly to a removable 250 GByte hard drive. Sample rates can be varied from 500 KHz per channel to 100 Hz per channel. You can even capture trend data at slower sample rates while embedding higher sample rate scope captures at the same time!

 

20 Analog Inputs
A wide variety of voltages can be measured by the Dash 20HF-HS. The four isolated inputs are ideal for high voltage or three phase power monitoring while the differential channels can be used to record and monitor sensor level inputs. Each channel input can be independently configured and has a dedicated 16 bit A/D converter to assure the most accurate measurement.

 

AstroDock Accessory
The AstroDock is a two-drive docking station that accepts the removable hard drives from any Dash HF-HS (high security) series recorder. The AstroDock connects to your PC via USB 2.0 and provides immediate review capability as well as direct transfer of data capture files to your computer.

 

Simply remove the 250 GByte capture drive from your Dash 20HF-HS recorder, plug it into the AstroDock and begin reviewing the data on your PC……all in seconds. Insert a new capture drive in your Dash HF-HS recorder and continue to record data while you review and archive on your PC. Working with large data files has never been this fast and easy!

 

Large 15" Touch-Screen Display
The Dash 20HF-HS has a large 15" color display which allows you to view your data in real-time and post capture. Operation of the Dash 20HF-HS is quick and easy with the intuitive touch-screen display. Interface icons and menus provide for straightforward setup and operation. There are no switches, push-buttons or other controls, complete operation is from the touch-screen. And, you can easily customize it to fit your exact needs. This means less setup time and more time for gathering data.

 

PC Interface
In today's environment, it is essential that your test equipment talk to your PC. The Dash 20HF-HS's GBit Ethernet port, USB interface and off-line software make it easier than ever to do this. From setting the system up through your PC to uploading captured data from the hard drive, the Dash 20HF-HS seamlessly integrates with your computer. Best of all, the Dash 20HF-HS comes standard with AstroVIEW X, our PC-based review software, making it easier than ever to review data.

(1) 10/100/1000 BaseT Ethernet for fast data transfer and host control (2) USB 2.0 for data transfer and connecting external peripherals (3) 8 TTL (0-5V) logic inputs (4) Link ports to synchronize capture between multiple units (5) Utility Port for Input/Output Interface (6) 20 ANALOG INPUTS !!!!! (7) VGA and keyboard/mouse port allow easy test stand integration

 

Secure Your Data
Each Dash 20HF-HS recorder includes removable system and data capture drives – perfect for streamlining data transfer or securing classified data. Use the AstroDock to review and transfer large data files from the removable drives to your PC quickly and efficiently.

 

Rugged Enough For Any Environment
Test equipment is only useful if it will survive your most harsh environments. With its rugged case and compact design, the Dash 20HF-HS can handle almost any condition you give it. Whether you need to gather data in a laboratory, vehicle, power plant or in the comfort of your own office, the Dash 20HF-HS is the data acquisition recorder for the job.
