    Wein bridge oscillator is basically RC oscillator with low frequency range and continuous sinusoidal output. Therefore, it becomes easier for an analog oscilloscope to find the faults in a Wein bridge oscillator.

    Logic analyzer is used in microcontroller circuit possessing a short hairline on two adjacent lines of data bus. This is so, because data bus conditions can be displayed simultaneously on various channels in addition to clock and control signals, which assist in fault identification.

    As MSO possesses high quality digital signal measurement capability due to waveform updation and large deep memory for higher resolution, it is used in a combinational logic circuit that produces glitches or hazards.

    Since DSO is known for delta measurement or propagation delay,it is adopted in a memory interface that is suspected to comply with set up and hold time requirements.
