Hi there,
currently i'm trying to determine the capacitance of capacitor in the most accurate way, with my material availabe. Right now i'm using a method where you can determine the capacity (determine Z --> alfa --> Z = Zcos(alfa) + jZsin(alfa) etc.) of a capacitor in an RC circuit. I'm measuring the phase shift, frequency and voltage magnitudes.
The thing is i'm using a Tektronix TDS 210 and i want to determine the phase shift more accurate. This oscillosocpe is not capable of measuring this by itself. I can use the delay time and period, using the cursor option, but i get the idea this is very inaccurate. Another restriction is that i can't use cursors in the XY-mode of the oscilloscope.
Any of you have any ideas for other options to determine the phase shift (or even another way to measure capacity with an function generator, oscilloscope, breadboard and alll kinds of resistors/capacitors)??
Thanks in advance!
