When troubleshotting a circuit using a frequency analyzer or spectrum analyzer what can it tell the electronic tech how the circuit it wrong?
I use a function generator set at Squarewaveform that goes to the input of a circuit, i use the frequency analyzer on the output of each stage to troubleshoot each stage of the circuit
If the stages are faulty or components are shorted or open what would the frequency analyzer display?
When i have used a frequency analyzer is displays each frequency components amplitude + frequency
So if the amplitude is lower or higher on some of the frequencys what would that mean when troubleshooting a circuit? a resistor is open or shorted? thats why it raised or lowered the amplitude at those frequencys displaying on the frequency analyzer?
How would you guys use a frequency analyzer when troubleshooting ?
Added after 1 hours 14 minutes:
A spectrum analyzer shows you what frequencies are contained in the signal you are measuring and what is the amplitude of each of these frequencies.
Yes, i know this is the basics
But when your troubleshooting stages or a circuit What are some basic or general spectrum analyzer problems? like would the frequencys be wrong or the amplitudes be wrong? and if they are what components or steps would you take after this?
Is it mostly a RC component problem ? Capacitors set the frequencys and resistors set the amplitudes of circuits and networks
So if the spectrum analyzer is displaying wrong amplitudes would mean its a faulty resistor in the stage? or network?
IF the spectrum analyzer is displaying wrong frequencys would it mean its a faulty capacitor in the stage? or network?
