265 Threads found on edaboard.com: What Oscilloscope
I am actually supposed to simulate the design attached below and observe the output characteristic on the oscilloscope for different values of base current on proteus. Anyway, what exactly I m looking for is this: . But I couldn't do it because there is no display mode or such on proteus' oscilloscope. I m not familiar w

If you connect an oscilloscope on the ACS712 output, what do you see?

I produce a rectified sine wave 1Vpp 100Hz using a PIC + DAC 12bits.
I would like to smooth the line by applying a filter.
what filter do you suggest?

I whould say, that it is almost impossible to figure out what it the problem without any measuring equipment like logic analyzer or at least oscilloscope. Your functions also not returning any error, you can't manage interface issues anyhow. It is just a lotery - will work or not.

Not sure if I can picture what you described, but I also accidentally burned equipment connected to the oscilloscope, on two occasions. In the first case, the oscilloscope was connected to the power socket without isolating transformer, and the ground of the probe shorted to earth of theelectric mains. In the second case, it was measuring 2 (...)

The waveform is what you can expect when measuring the oscillator output with a regular oscilloscope probe, most likely using a long ground clip cable.
It mainly shows the limitations of your measurement equipment, respectively your way to use it. Simply impossible to get trustworthy rise and fall time measurement this way.
To suggest better

I want to create a complicated signal (near guassian) as input in proteus.
I know that i should use FILE type of generator mode in proteus.
but when i give a file with 2 columns as volt vs. time and connect it to an oscilloscope it shows nothing. i put here my input file.
any help is appreciated

I really liked the discussion it is very informative. But my issue is some what different.
I have joined a project and in lab we have 4GHz OS and Network Analyzer and still they want o buy 4GHz SA.
From the discussion above I can make clear picture of OS and SA but it would be great for me if someone also includes Network Analyzer in the discus

I have found this little oscilloscope project (URL) that uses a single A/D converter connected directly to the LPT port. It uses one pin of the port as an EXT trigger, which is desirable in my application. The author notified me that it can display signals up to 30-40KHz or so.
1. I wonder, what is the thing that limits the display of signa

How simple can it be designed/done ? what would it take ?
A single channel, 100KHz bandwidth, no storage, VGA output for that spare old monitor sitting behind the spider webs...
Or has it been done and there is instructions on the net ? Or such does exist in kit form ? There is many cheap oscilloscope kits but for smaller LCD displays.

I tried to verify the values manually (by using oscilloscope and testing several address lines)
what exactly do you mean by manually ?
How did you make the manipulation of logic levels on pins ?

Hi, I'm trying to model a sinusoidally driven harmonic oscillator using RLC circuits using LTspice IV. I get a reasonable result for the series RLC circuit, but not for the parallel circuit. Can anyone catch what I'm missing?
Ideally they should both give me the same result.
Attached files show circuits and AC analysis results.

If you want to trigger the trace to capture a spike you ideally need a storage oscilloscope so it can show the spike itself and not just what happens afterwards.
The best you can do without storage is to set the trigger level to a point just higher than the highest normal voltage in the signal, this will unlock the trace so it free-runs and probab

If you ask me what piqued my interest in electronics, it was the Tek 545 scope.
A short story:
My father, an architect and avid stereophile, built a home for the owner of a local broadcast station.
That person brought home one day the station's scope, hooked it up to the stereo amplifier, and played some music.
To me, seeing the wavy line

We need more information.(HF RFID is wireless, not SPI)
what EEPROM device is it?
Does it contain a write protect feature? (Sw or hw)
Are there other devices on the SPI bus?

Are you taking into account the current flowing in to the volt meter itself?
It is unusual to configure a MOSFET circuit like that, the resistor is a 'pull down' and the switch connects the gate to ground to turn the MOSFET on. Is that what you intended?
There will be some leakage into the gate as well, it will be very small but 4M limits the po

With just a brief glance at your two links, it seems to be a hardware kit that you can re-configure via software and view the results on the computer acting as a oscilloscope (CRO). There is no indication of what signal sources(real or virtual). Or even whether the simulated circuits and related to the plug in board, I.E. if you put a DVM across

I have problems with MOSFET overheating, while switching resistive load (resistor and LEDs). For driving a MOSFET (I'd tried with two different ones - FDD8444 and NTD3055L104) I'm also using a driver MCP1416. I've made some images with oscilloscope. Can someone explain me what is going one? Why is there a curve on the top of the square signa

Sorry the first wave form is feedback pin ie giving close to 2.5V, second and third are gate pulses, you can see a narrow pulse coming in between, it was intended to switch at 100kHz but varying too far 20kHz range so i thought , this may be caused by current sense spike so 4,5,6 shows current sense waveform with best of my probing techniques..

what do you mean "the jitter needs to be lesser than the reference value." what's the reference value? Do you mean the 25MHz clock? There are devices called "jitter cleaners" that might be what you want-they are basically PLLs with very narrow filters. Look at TI, IDT, etc.
Is your proposal to use two synchronous clocks? If they're not (...)
