I could be wrong but I doubt that it will work. It looks like a variation on the DSO138s I have and they are absolutely useless for anything but audio. They are rated for 200k but can't even properly display a 25kHz PS drive signal. You can try it but don't be surprised if it doesn't work.
Define 'scope'? I can tell you definitively that scopes like the DSO138s I have absolutely do not have enough bandwidth to display a 25kHz square wave. Without being able to properly display a square wave properly, the scope is useless and could be so misleading that trusting it could be worse than no scope.
Do you have a laptop computer or a desktop computer that you will have on your workbench?

The OWON VDS1022I (<<< the I is very important as it signifies 'isolated') is the cheapest scope that I've found that will do any useful work.
You should see if the one you have works before buying anything else.
Do you have any other amplifiers that you could test your scope on?

Excuse the quality of the handheld images.
This is what my cheap scope does. The low frequency is 20kHz (10us) The high frequency is 80kHz (2us). 80kHz is just about the lowest frequency that class operate at and you can see that the cheap scope cannot properly display it. The OWON does an acceptable job but the CRT scope gets it right (clean and clear). I know CRT scopes are a luxury nowadays.
What other amp do you have that you have to check the scope with?
