Spider-20 Portable Wireless Dynamic Signal Analyzer
The Spider-20 from Crystal Instruments is a full-featured analyzer in an easily portable, battery-powered, handheld package! It offers four 24-bit inputs, tach input, ICP® power, 6-hour battery life (swappable), built-in WiFi, and more. The system can operate in "BlackBox Mode" - no need to have it tethered to a PC full time! Set up testing with a PC in the office - once in the field, simply use the Power | Start | Stop buttons on the Spider-20 to control your measurements. A wired Ethernet connected option is available as well.
