set probe on T4 and T5 and tell what signals' widths you see.

[chuubaba]

Kindly tell me what scope settings for TIME/DIV ?

[kt315]

click... click... click... and you see a signal filling a half of the screen.
try 10us/div.

do not ask me how control by your car if i'm on back seat of it and you are driver.

[chuubaba]

This i see on 10uS/DIV.

This i see on 2mS/DIV.

I am unable to understand it.

This i see on 5mS/DIV.

......do not ask me how control by your car if i'm on back seat of it and you are driver.

This is a confusing signal. No harm in asking for advice. BTW you ar not on the back seat. Be a good navigator.

bad. i think you see a clog on signal from your converter. i do not see the signal itself here.
you have to see rectangular impulse with approx 10V amplitude.

I recalibrated the probe.
Now on 0.5V/DIV 10uS/DIV i see this for T4 and T5 .
Pulse width of 42uS??

[kt315]

just one Q. why WHY you did not see THIS signal right on i asked you to give it?

ok. good. thats all on today. enough.

[chuubaba]

thats all on today. enough.

The width of other signal is 85uS on T4 and T5

[kt315]

scale? uS/DIV?

[chuubaba]

scale? uS/DIV?

[kt315]

you have to see whole period. click timing scale on 2ms (MILLI--).

I have closed the workshop.
See new photos in my previous post.
Whole period 42uS + 85uS = 127uS ??

[kt315]

practical guide you ask. waste a time to read it.

[kt315]

Whole period 42uS + 85uS = 127uS ??

this is just your fantazy period. our period has to be sure 10ms. 10ms gives us clear 100Hz frequency.
