I believe you know that +/- 35V is no voltage range for a standard OP. So you have essentially these options: - use an expensive high voltage OP - design a discrete buffer amplifier - use a passive voltage divider, similar to an oscilloscope input
Hello, I was wondering what the explanation for the following observation is: When looking with an oscilloscope at the clock signal that I generate with a microcontroller I do _not_ see an expected amplitude range of 0V to 5V but a large overshoot blow 0V and above 5V. See attached image. Are these amplitude real or just some sort of artefact
I need an attenuator to scale down input voltage +-220V to 0-5V for my oscilloscope project. What would be the best way to do it? I have thought of using an opamp in inverting mode. But will LM324 accept 220V input?

I need the sch of input stage of an oscilloscope?(20 or 50MHZ oscope) Is there any sch for tektronix oscopes?(input section)
When troubleshooting GAIN , what is the best way to know the input voltage VS the output voltages? For preamp amplifers for a 6 stage or 8 stage preamp sections, how do i know the GAIN is correct? PROBLEM example#1 The preamp has 8 stages, its suppost to have 6 divisions on the oscilloscope set at (...)
What kind of noise? Try using your oscilloscope to identify the type of noise and to locate its source. Maybe the wires to the potentiometer are too long, causing crosstalk or feedback. Maybe your amplifier's input stage is unstable, causing it to oscillate over some range of input resistances (potentiometer (...)
Hi, i need schematics / docu and tutorials for good input stages for oscilloscopes in the range up from sevreal 10 MHz to 200 - 300 MHz. Please help me ! best jk
