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...


oscilloscope without wire ground

Is there any risk to use oscilloscope without wire ground? Because with wire ground there is a short circuit when I use GND on the line.

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.

At least interesting to me. On the advice from members of this newsgroup I bought a 465B TEK oscilloscope. It comes in handy now and then. Yesterday I had to replace a power supply in one of my CNC machines. The only one available in a reasonable length of time was a used one of unknown quality. I spoke to a friend of mine and he said to 'scope the thing and look for any ripple on the DC out...

To All, Several years ago I was looking here for advice about buying an oscilloscope. The unit that got the most votes for my price range and experience was the Tek 465B. So I bought one and then later someone who used to post here sent me the meter kit that Tek used to sell and I installed it on the 'scope. The 'scope is way more than I need and so it has never let me down. Now I think I co...

Greetings Everybody, My son brought by today an old oscilloscope. The Brand is Lambda and the model is MM-2. On the back are three pairs of terminals. One is marked with G & V, one G & H, and the last pair R & S. So the first two pairs are pretty obvious, horizontal and vertical, but I don't have any idea what the last pair is for. The screen is about 2 inches in diameter, and is marked with...

I'm trying out the SPI module on a PIC32MX150, and I've encountered something I wasn't expecting. The pin selection / module enabling stuff is done, and I get i/o, but the Slave Select pin only goes 0-1.2v, rather than 0-3.3v like the clock and data pins. I tried a 10k pullup resistor, it stayed at 0-1.2. Nothing is attached to the pins except the oscilloscope. I've hooked up two...

My main question is about PC USB-based oscilloscopes. The rest of this is specific to my problem(s) and may be overlooked. I'm using cordless drills to power electric bicycles. I have one built. It works but is underpowered. I am building a better one using a DeWalt DCD995. Some nice electronics included in that drill, a stout (very tight turning) brushless motor with a controller. ...

Hello I worked in a place that gave me access to budget, non memory 20MHz CRT scopes - I no longer work there. They were perfect for my needs. Six years on and I find I need an oscilloscope, the market seems to have changed. Are those cheap digital models any good? I need reasonable Y sensitivity (5mV/div), up to 5MHz, storage would be nice, it's not for radio work. I found things l...

I have a 4500 watt generator that is for emergency use. When it was new I checked the output with an oscilloscope just to see how pure the sine wave was and how close to 60 Hz it was. Well, the main sine wave looked good and the frequency was very close to 60 Hz. It floated around a little as the load changed but then would stabilize very close to 60Hz. However, there were lots of other small...
