• Do make sure that each stack connector is properly seated in
place before trying to stack another channel on top
• Don’t allow water or dirt etc to enter the scope via the stack
connector access hole
• Do remember that scopes in the stack are NOT isolated from
each other, they are only isolated from the USB ports. To
re-iterate, stacked scopes have their BNC connector bodies
connected together through the stack connector.
2.3.2 Non-Stacked (MIS) Mode
It is also possible to use multiple USBscope50s as independent
instruments. In this mode, the scopes are NOT connected together
via the stacking interface

.
This configuration is also termed Multi-Independent-Scope mode or
MIS mode.
In MIS mode, each scope can use its own timebase setting, and each
scope input will remain electrically isolated from the others (unless
you connect their BNC grounds together).
2.3.2.1 USB Connections For Non-Stacked Configurations
All scopes need a USB connection. A standard hub may be useful
for multi scope use to get enough USB ports.
Each scope needs about 200mA. Plugging more than 2 scopes into a
hub will mean that the hub may need to be powered externally.
Please refer to the hub’s documentation for more details about the
power available per port.

They can of course still be snapped together, but remember NOT to fit any of the stacking connectors
so that the scopes remain electrically independent of each other.
