@BTCInstrumentation thanks for reply. you will find "scope" option in "analog" tab.
Finally I am able to measure dc and ac all in scope. my mistake is It's input parameter is in af analyzer screen. you are doing a great job keep it up.

THANKS! I bought my first scope a recently a Tektronix 2225. This video helped solidify my understanding of the AC/Gnd/DC input coupling. 5 stars

Great info to get us "newbs" started! I like how you explained that the scope is simply a graphical volt meter. PS- how would i go about connecting the scope leads to 120v AC house current? I'm curious to see the waveform that our outlets actually generate. Thanks!

@na5m You go about is very cautiously. Don't ever directly connect an oscilloscope to line power, but use a step-down transformer instead. This not only reduces the amount of voltage applied to the scope's input, but it also provides galvanic isolation between the line and you to prevent ground faults.

I want to see crystal freqency in scope. 32.768 khz crystal. how can I see its waveform in scope. can you please explain me.

@yousrihari Connect the scope's probe in parallel with the crystal. You may have to use two probes (in differential mode) if one of the crystal terminals is not grounded.

Thanks, I have HP AGILENT 8924C ANALOG SCOPE. I am unable to see 9v dc in it. What parameters I have to set like v/d, t/d etc., I don't have ac/dc coupling parameters in it. guide me.

@yousrihari I'm not sure you actually have an oscilloscope. I tried looking up "HP Agilent 8924C" on Google and it appears to be a communications analyzer, not an oscilloscope.
Any oscilloscope set to "DC coupling: should be able to register a DC voltage applied to its input. The volts per division (v/d) setting determines how far the line will move with applied voltage, and the t/d setting doesn't matter (for DC measurements).
