The correct Oscilloscope Probe Calibration diagrams.

@TK,

I read the Manual and found the correct Oscilloscope Probe Calibration Procedure.  The correct photos are shown here.  Thank you for all your comments - they refer to incorrect photos.  All my posted data are correct as the calibration was done right for me when I brought the Scopes.

@testers and All researchers.

False Alarm from TK.....  I did not give him the correct calibration diagrams.....  The pictures on reply 450 are definitely not calibration pictures.  Should not blame TK for not recognizing them as oscilloscope manufacturers have different displays.

Lawrence,

I would hardly consider the post 450 scope shots a "False Alarm".

Irregardless of any channel's vertical sensitivity settings, the displayed waveform of the signal at your scope's calibrator post should always indicate approximately 3 volts pk-pk.  Additionally, the displayed waveform should appear square with little undershoot or overshoot, indicating a flat frequency response.  All but one of your scope shots indicated a frequency response that rises with frequency.

The wierdest display is scope 1 channel 2 wherein 15volts pk-pk (at low frequency) is indicated from the approximately 3 volt pk-pk signal at the calibrator post.

You should investigate and/or explain why that channel on scope 1 is not indicating the proper amplitude.  Even with the probe and channel attenuation settings mismatched, it is difficult to understand how scope 1 channel 2 is indicating high by a factor of 5. 

Are you using all probes switched to their X10 setting and with the scope channels also set for X10 probes? 

The post 450 scope shots do not lend much credence to the accuracy of your previous data.

IGNORE ALL PICTURES FROM REPLY 450!!!!!!!!!!!!  THEY WERE WRONG.

That is the point!

The question is why are they wrong?

As you have relied heavily on the use of these scopes to prove your technology and present your data, surely you must see that a better explanation of the 450 captures is required than just "ignore them".

Oh well...

Ok, fine.. ill be the one that will point at the elephant in the room!

The pictures on reply 450 were wrong because I did not press the "default setup" button first before doing the calibration.  The Atten Oscilloscopes have many options and settings.  For normal operations, I had to use specific settings depending on what I wanted to display.  For example, I displayed Ch1 Vpp, Vrms and Ch2 Vpp, Vrms, etc.  To do the calibration of the probes correctly, very specific setting was required.  The Atten Scope has the "default setup" or "factory setup" to help to achieve that.

I did not press that button first and thus the "calibration pictures" were wrong.  A simple error.

*** This is actually a good experience.  When I bring my Atten Scopes (or use new ones) at one of the Top Universities, I shall do the full calibration procedure in front of the Academics.  The results will be more convincing.  It also points out the difficulty if I rely on "their oscilloscopes".  There is no possibility that I will be able to master the operations of all different models of oscilloscopes.  Bringing one or two Atten Scopes for demonstration is a MUST.  (Bringing a laptop computer is NOT.)
