This following image is of Xoscope output showing two timer circuits. They have the same capacitors (47uF), but one has a 161.5k resistor while the other has a 510.5k resistor. The difference in the resistors causes different timing in each circuit. So this means to get the timing difference we divide 510.5/161.5 which equals 3.16 then, look at the picture to see the green line "which has the 510.5k" shows one space, to every three spaces the blue line "which has the 161.5k" shows.

I'm using both Tektronix probes, one model P6109, the other P6109B, on board 16 bit audio front mic input soldered to two BNCs which gives left and right.

Next, maybe give the system a sense of direction.
