Now that I've had some time to accustom myself with my 7CT1N, while I can make lots of pretty pictures, I'd like a better understanding of what information I can glean from the results, particularly for bipolar transistors
From what I understand, STEP AMPLITUDE is an indicator of fixed base current per step and the AMPERES/DIV determines the vertical scaling. If the STEP AMPLITUDE is set to 10uA and the AMPERES/DIV is at 10mA, if I display just two traces and the vertical spacing of the linear portions of the horizontal lines is 1 division, I presume that indicates the transistor's current gain is 10mA/10uA = 1000. Is that correct?
Also, I'm curious as to how to properly set this up with the tracer in a horizontal slot and using a vertical amplifier. With this configuration, I can change the vertical attenuation as I want and, thus, am not sure how to calculate a proper vertical AMPERES/DIVISION value. Using it in the reverse way (the tracer in a vertical slot and a time-base capable of acting as an amplifier in a horizontal slot or just an ordinary amplifier in a horizontal slot), I don't have control over the vertical attenuation and I presume the AMPERES/DIVISION is direct-reading but that might not be correct.
Apologies if this is extremely basic information that should be obvious to me by now.
Thanks,
