Hi all, I have finally decided to break down and buy a oscilloscope. But I found I don't know what to get. As this will be by first oscilloscope I don't need any thing fancy. I don't have a lot of money so a used one would be fine, if it had a manual or I could get one. I would be willing to spend maybe 60.00 usd for the oscilloscope. I did find http://www.omega.com/pptst/HHSM310.html but I ...

Hello, I've been trying to learn how to use my new Protek 800 series hand held Digital Oscilloscope. So, I connected the single oscilloscope probe to the output of a used function generator that I bought on EBay. On oscilloscope auto, what I see is a waveform that I can only describe as a repeating sinc function. When I increase the frequency of the sine wave on the generator, I see more...

As I get more advanced at creating circuits, I can see the benefit to owning an Oscilloscope. I'm on a fairly tight budget, and was hoping to get a recommendation on a cheap oscilloscope that is "good enough" for hobby work. I've used one at school years ago, which probably had more bells and whistles than I would ever need. What features are essential for a hobbiest? What can I do with...

Hello all, I have been fooling (emphasis on fool) with an old Heathkit 10 MHz two channel oscilloscope, which I believe was built in 1976 (it was given to me several years ago). I have been able to calibrate the voltage on one channel, but not the other. Sometimes, after I have spent some time probing old pinball machine circuit boards using the one good channel, the voltage flakes ...

I recently built the JYE Tech DSO-150 Shell oscilloscope kit (#15001K) that I got from Banggood for $24 plus a power supply. These are single-channel, low-frequency scopes, but would be useful for things one might do with an Arduino or similar microcontroller, such as stepper motors and servos, plus of course general audio stuff. The bandwidth spec is 200 kHz, but I suspect the display...

Hi, is there any PC Oscilloscope for which there exist Linux software under BSD or GPL or similar license? Naturally if the hardware (FPGA) is documented at circuit level - even better - witch I doubt. I am even open for self construction kits if they are well documented and working. They should use Xilinx FPGA though, for which there are free entry level tools. Then I must say tha...

Hello there! I have an Instek GDS-2202 digital storage oscilloscope. I am trying to figure out how to setup my scope to minimize the pick up of stray 60Hz mains signal. If I change my scope's vertical sensitivity to 20mV/div, then I can see the 60Hz signal. The signal's amplitude increases even more when I turn on my DC power supply. I can pick this signal up without even connecting the pr...

I've heard 'no never do that' and 'it'l blow your fuse / you will die' etc... just trying to understand. As long as you are careful to connect your probe ground to neutral and the probe signal to hot, it should be ok right? Assuming the scope can handle ~350V peak. No i'm not going to try it. I have a little AC walwart to use as isolation.
