• Notes

• This is a signal generator that generates square waves which makes it possible to perform measurements in equipment with audio up to high radio frequencies.

  In order to achieve perfect square waves, the following components must have equal values: R3 = R6; R4 = R7;  R5 = R8 and C6 = C7.

  In case of testing a receiver output bus A is connected to the chassis, whereas bus B is connected to a point in the receiver circuit, depending on the section to be tested.
