Saelig's Miniature 10MHz Scope Adapter Offers Signal Isolation

Saelig Company, Inc. has introduced USBscope50 - possibly the world's smallest USB DSO (Digital Storage Oscilloscope). USBscope50 combines a very small form factor - similar to a memory stick - with the high performance normally associated with much larger bench-type products. Powered from a USB port, USBscope50's modular design allows the user to configure a single channel or up to 4 channels when using multiple adapters. A proprietary synchronization system insures tight signal channel-to-channel matching and concurrent triggering. USBscope50 is small enough to be carried in a shirt pocket or laptop bag and uses standard BNC oscilloscope probes.
USBscope50 offers lots of features common on bench scopes, such as AC/DC coupling, programmable trigger threshold and edge modes, pre- and post-trigger, programmable input offset, 50MSps 8-bit sampling (1Gsps equivalent time sampling for repetitive input waveforms), 3V/30V/300V input ranges with a x10 scope probe - but adds features sometimes unavailable in even expensive scopes, such as 300V Cat II galvanic input isolation between BNC ground and USB ground. This means that there is no DC path through USBscope50 from the scope ground clip to the PC's ground. Measured signals can be displayed with the supplied scope software, as well as stored or printed on the attached PC.
