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
It's not the oscilloscope input stage but maybe the probe, typically the ground clip. It may be real as well, depending on the circuit. A CMOS IC, e.g. a ?C will usually clamp the voltage 0.7 V below/above the supply rails. Seeing no clipping at all suggests that it's a measurement artefact. Overshoots can damage sensitive components, (...)
Hoping not to be offensive, reading your question I think you are not familiar with electronics. An LM324 cannot accept 230Vac between its + and - input terminals. If galvanic isolation is not of importance, a resistive voltage divider is used in most cases. However a general-purpose resistor cannot handle 220V safely. This means you need spe

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
