We found this circuit in a 1982 documentation. It uses a CA3140 or equivalent operational amplifier and does not require a symmetrical source. The output is 1 Vpp wide.
This simple transistor tester was found in a Japanese magazine in 1967. It tests general purpose...
Short duration pulses or "clicks" can be generated with the circuit seen in the figure. The...
A 25 mVpp applied to the input of this circuit produces in the output a 1 Vpp signal. The...
