OT USB Scope Question
Locked
 
|
A bit off-thread, but sort of related - wondering if folks on this reflector have any experience with USB oscilloscopes. I'm considering adding an o'scope to my test bench, and came across an Australian company called Bitscope.com. They have several models and appear quite affordable. The nice thing is they work on Windows, Linux, Mac OSX, and Raspberry Pi.
I'm a bit limited not only on funds, but room for additional equipment, so one of those big analog models is out of the question. Anyone using a Bitscope unit or any other USB scope here on this reflector?

Hi Jim,
I have one 200 - 800X usb scope, use it every day to inspect for proper connections, board issues, and the like. It is made in china, the manual isn't. But it runs under windows 7 - 10 and is pretty straight forward. Now that I have one.. not likely to work without one. Have a great day, --... ...-- Dale - WC7S in Wy > From: [hidden email] > Date: Tue, 29 Sep 2015 14:31:20 -0700 > To: [hidden email] > Subject: [Elecraft] OT USB Scope Question > > A bit off-thread, but sort of related - wondering if folks on this reflector have any experience with USB oscilloscopes.

HI Phil,
The PC based scopes rely in the sound card.. and from its limitations, I have gotten only as far as using Spectragram by Visualization Software.. While quite nice for what it does.. a nice Tek 2235 can't be replaced. Have a great day, --... ...-- Dale - WC7S in Wy Subject: Re: [Elecraft] OT USB Scope Question To: [hidden email] From: [hidden email] Date: Tue, 29 Sep 2015 16:39:38 -0700 Dale, Seems like yours is a microscope. I think Jim was asking about some sort of usb oscilloscope (which I've never heard of!). 73, Phil W7OX On 9/29/15 4:25 PM, Dale Putnam wrote: Hi Jim, I have one 200 - 800X usb scope, use it every day to inspect for proper connections, board issues, and the like.

Hey Jim,
One thing to remember with any digital scope is that you need to watch out for digital sampling artifacts such as aliasing of signals in question. There was a ham I knew that kept complaining that his AD9850 DDS module was operating on two different frequencies, sometimes at one frequency and sometimes at the other. I could not convince him that this was a result of aliasing WITHIN THE SCOPE itself. He bought additional DDS modules, surprise! They did exactly the same thing. Then, he bought an old analog scope and no longer saw these problems. I do have and use a USB scope "in the field", but I am careful to understand what that scope is telling me. I also have a couple of analog scopes, one on the bench, and one portable. I can verify questionable results with them. 73, Terry, N4TLF -----Original Message----- From: James Bennett Sent: Tuesday, September 29, 2015 5:31 PM To: Elecraft Reflector Reflector Subject: [Elecraft] OT USB Scope Question A bit off-thread, but sort of related - wondering if folks on this reflector have any experience with USB oscilloscopes.

Hi Jim,
For a number of years I used a Fluke 97B 50 mhz scope. Picked it up for $50 bucks on Ebay and used it for a number of years then sold it for $50 bucks. :-] There are some youtube reviews of PC type scopes you might check out. Best!

I'm assembling a Softrock Ensemble RXTX rig, most likely for use as a 24x7 WSPR beacon; there are several construction steps where optional testing beyond the basic voltage, resistance, and current measurements can be done with a scope.

Although I don't own one, these devices seem to be improving all the time
and I wouldn't hesitate to buy one over no scope, or in addition to a "real scope" -- budget permitting. I'd do a little online hunting for features and reviews that would best fit my use cases. Just a quick glance at the range of devices available in the PicoScope range shows everything up to 12GHz bandwidth, 16bit sample sizes and many inputs. Many also have signal generators built in, which could make testing filters/traps/etc. a snap. I'll share one interesting thing I was told by a representative of one of the manufacturers at a show. I was talking about the performance of the devices they were exhibiting and the possibility of getting the raw digitized data into my own code. While that was suggested to be possible, when I said I was considering trying it as the front end to an SDR he pointed out a significant problem. He pointed out that the A/D in the USB scope box ran too fast for USB, so the computer doesn't get all the data, just bursts of signal. That works perfectly for a scope which by it's nature doesn't display everything but would be useless for SDR. Hope that is helpful, - Brendon / KK6AYI On Tue, Sep 29, 2015 at 7:16 PM James Bennett <[hidden email]> wrote: > I'm assembling a Softrock Ensemble RXTX rig, most likely for use as a 24x7 > WSPR beacon; there are several construction steps where optional testing > beyond the basic voltage, resistance, and current measurements can be done > with a scope. > > Jim Bennett / W6JHB > Folsom, CA > > > On Sep 29, 2015, at 2:41 PM, Nr4c <[hidden email]> wrote: > > > > Do you want scope for audio or RF?
