Adding Sweep Out To A Hameg 203-4
I'm looking to add a sweep output to my Hameg oscilloscope so that it can be used with a wobbulator.
The max sweep output from the Hameg is 4.4V at 200ms/cm to 1.5V uv/cm. This is too little to drive the reactance valve of the wobbulator.
Chris55000 suggested a "Dual Op Amp Preamp DC Amplification Board NE5532" and a 741 op amp. This will be ordered soon.
I can feed it +12V and -12V from the scope's PSU. I'm not sure about L+R inputs and outputs. I know where the sweep signal comes from.
Has anybody done this before?
