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, My company wants to buy an oscilloscope. The scope that meets our needs is around $7,000. I am sure we can save much money if we buy a PC-based unit, like Picoscope. Do you have experience with PC based scopes? Do you recommend them for serious work? Thanks

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...

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 ...

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...


oscilloscope without wire ground

Hi, I have been playing with USB using Ztex's USB module. I plan to make an oscilloscope and function generator. Therefore I would need an AD and DA chip with 12 bit resolution. And quite fast ones also. Plus I can't really handle the surface mounted ones yet, so DIP would be good or a break out board with DIP pins. Could someone please point me in the right direction. Then other s...

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.

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...

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...

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...

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.

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...
