How do I measure something like that with oscilloscope? Can I put signal to one and GND to other output? Or do i need to use 2 probes and get the difference?
Hi,
Probably a stupid question. What is an easy and cheap way to measure crystal oscillators? F.e. this:
https://eu.mouser.com/datasheet/2/698/REN_XL_Crystal_Oscillators_Datasheet_DST_20220302-1954959.pdf
I know it's easy with oscilloscope but would it be possible with frequency counter as it's...
Hi,
I have this Flying probe that has "AC200V IN" lable on it but input is 3 phase.
The machine has Japan sockets. I'm in Europe.
What voltage could it need?
edited stupid mistakes.
Hi
What is a service pin used for. In the datasheet it says:
I/O (Built-In Configurable Pull up) Service pin (active LOW). Alternates between input and output at a 76-Hz rate.
But I don't get what its used for and how.
Hi
Could someone give me some good resources where I could read more about how it works, what each component is for etc.
What I'm trying to understand is the schematic below.
Actually it a DC motor but I get it now. This way you can apply more power to the motor.
I have another question about the image below. Why are there the marked connections to power supply and ground?
Hi
I came across a H-Bridge FET Driver design where both high side outputs were set high (both high side inputs connect to the same microcontroller pin) when the motor was run in either side. The direction and speed was controlled by giving a PWM to low side input corresponding to the direction...
Yes, DC resistance. Measured with a multimeter.
But I don't get why I get different results (same component in the same place, different items):
fluxuating reading that steadies at 5kohm after a few seconds
fluxuating reading that steadies at 28kohm after a few seconds
infinite resistance...
I know that I can measure if the capacitor is damaged by measuring its resistance.
What I'd like to know is what effects the measured resistance of a capacitor because I've gotten different results from same capacitors.
Hi
I have had a problem with ceramic capacitors shorting out (voltage peak too much over rating). I found out that I can easily detect a it by measuring resistance and if its some ohm then its shorted.
But my question would be what effects the resistance reading of the capacitor? Sometimes I...
I have an at90usbkey board:

I'm thinking of using it to drive optocouplers from io pins. The question is where on the board should I connect the ground from the optocoupler. the board is quite small, where would be the best place?
