I use my Oscilloscope to make XY plots of audio LR signals.When the input signals go off the trace becomes a bright spot, and will burn the CRT.
Any suggestions on a Spot Killer circuit that uses the Z input to adjust the intensity down ,or off ?
The audio input signals are are as low as -10 dBv, when the signals are lower or off: I would like the Z output to switch from zero volts to either B+or B- ( +/-10v ) when blanking . And return to zero when the audio returns.
