EJP,
I discovered that 100mV/div agreed with when using a timebase in a horizontal slot and presumed that was correct but I really need to READ THE MANUAL! :)
Thanks,
Barry - N4BUQ

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?
Yes. See manual p.1-8. beta = VERTICAL AMPS per DIV/STEP AMPL.
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
No. You are supposed to set the vertical amplifier to 100mV/div, and then
control everything else on the 7CT1N. See manual p.1-1.
I presume the
AMPERES/DIVISION is direct-reading but that might not be correct.
Correct, with the 100mV/div proviso above.
