PC based oscilloscope for basic use--worth it?

I'd like to grow up to the next level of electronic design--time to buy an oscilloscope.

This PC version for $60 seems too good to be true.

Any knowledge of these?


Thanks in advance.


Buy a real scope.
Look at Rigol


google sound card scope.
if you are looking for basic information, it could help

You really need to think about what you need a 20 mhz scope is not much good on a 16 mhz uC
you need a 40 mhz.
I would go for a good 8 channel logic tool way more useful.
And a sound card scope is fun to play with and look at sound but it’s too slow to be of much good.
There are good usb scopes but I would go for one that’s faster and one that’s for logic with 8 channels.

The long discussion in this Thread may be useful.

I bought a SainSmart DSO203 because it was affordable and small. I don't have much storage space and I don't use it very often. I am very happy with it but YMMV.

In some circumstances a stand-alone device can be very much more convenient than a PC-based device.


I am looking at the problems I have:

  1. Serial programming port pull up on the DUE, that is at 9600 currently, max 115000 (I think).

  2. i2c temp sensors running on long lines on an UNO.

What do I need for that?

What about something like the Raspberry Pi version?:

Something like this http://www.mcmelectronics.com/product/SEEED-STUDIO-109990065-/72-12890

Have a look at the Bitscope Micro. With the logic analyser software it includes decoding of SPI, I2C, and CAN bus. As an oscilloscope it lacks a lot of the facilities of a Rigol or Siglent but is a good start at a reasonable price.


Check this one out
The engineering students at Rensselaer Polytechnic Institute (RPI) have to buy one for their engineering lab classes. College student price was $99 last year, maybe less than shown due to RPI buying in bulk. Still, $159 not bad if you know a college e-mail address.

When I was in first year at Batersea CAT we had to put up with these! Later we progressed to the Telequipment D43. :slight_smile:
Students have it easy now?
