Oscilloscope IOs with the BNC adapter connected


I mounted a BNC adapter to a Analog Discovery 2 on a acrylic plate (see Pic)
In this configuration the 1+, 1-, W1 and W2, are marked NC, NC, NC, NC on the BNC and are disabled.
Is there a way to bypass the BNC and make those pins active again without removing the BNC adapter?
Is the same true also for the Breadboard Adapter?
In other words, is there a way to make the BNC adapter work together with the Breadboard Adapter?

These pins are disconnected from pin header in order to minimise parasitic parameters, I suppose. The only way to use BNC and 2.54 connector would be to solder some wires, but being aware that negative terminals of the scope are hardwired to GND. On the breadboard adapter all signals are routed to connectors.


And you can use breadboard adapter with BNC adapter but with analog signals provided and probed using BNC cables/oscilloscope probes

Hi @squarenut,

Indeed in the BNC adapter you no longer have access to W1, W2, Scope 1, and Scope 2 in the 2x15 connector since they are connected only in the BNC connector. 

Regarding the breadboard adapter, all the signals are routed in the straight connector from the board, therefore you can see them all marked on the label. 

If you want to use the breadboard adapter with the BNC adapter, in the breadboard adapter you will have access just to the digital pins and GND since you can't get out the signals that are not connected.

However, why do you need the BNC adapter if you want to use wires on the breadboard, or why you need output on the 2x5 connector if you plan the use the BNC?

If you don't need the BNC probes in particular, you can use the breadboard adapter, only.

Best regards,
