USBscope50 USB PC Oscilloscope
General Frequently Asked Questions
Does the Scope work well with USB1? Don't you need to use USB2?
USB1.1 is plenty fast enough for the USBscope50. We preferred USB1.1 over USB2 because USB1.1 is supported on more hardware platforms, and is lower power. If necessary, we may consider USB2 for future product designs.
Can I use x100 probes with my USBscope50?
Yes you can - but remember that the USBScope50 software won't compensate so you'll need to remember to adjust your readings accordingly.
What is the lower frequency response like, i.e. in the region 0.1Hz to 10,000Hz
The response in DC coupled mode is fine across that range. If the signal must be AC coupled inside the scope then the 3dB point is about 3.4Hz and runs up to the full 75MHz.
Can you synchronise multiple USBscopes to get phase data?
Yes you can, just like any other scope
Can I run more than one scope if they are not stacked together?
Yes, there is a mode called "MIS" (Multiple Independent Scope), where you can launch several copies of the application software and have each copy drive just one scope. In this mode, each scope works in a completely stand-alone way, and will also be isolated from any other scopes. The MIS mode requires that the scopes are not electrically stacked together using a stacking connector.
What is the smallest signal I can see with the scope?
With a x1 probe, signals below about 10mV are hard to see.
