Huntron has pushed the principle of the octopus x/y curve tracer very far, but the Hameg component tester is already very useful.
For troubleshooting, I find it essential.
It is not really necessary to have the display of 2 curves, nor to have different frequencies and output levels.
crt display is still a winner for such application as dso is not good for x/y display.
Even the Hameg octopus adapter HZ65 has became hard to find and expensive....
