PC oscilloscope software

There are several options if you are looking for PC oscilloscope software. If gone through a few below and l given short reviews. If you just want to know what the best  one I found it's Scope v1.46.

Winscope

Winscope is an oscilloscope program for windows using a soundcard input, so works perfectly for the oscilloscope buffer hardware. It was originally written for Windows 95 but I can verify that it works on Windows 10. The last version I have been able to find is V.2.51. It’s also free.

It is a dual trace oscilloscope with spectrum analyser, if you use both channels on your sound card. With a bandwidth of 20 Hz to 20 kHz once installed its fairly easy to use. The buttons on the top are used to set the scope.

The first button selects play, which starts the live waveform display. The second pauses it, the next two buttons select single and dual trace. After that is the XY select button.

Although basic the Winscope can do Lissajous patterns in XY mode, point-and-click waveform and spectrum meter functions. Plus cross-correlation coefficient measurement and storage tube emulation. I’m not sure how many of the later functions you would actually do on a scope of this specification but if you want to play around with these functions they’re there for you to use.

One of the limitations I found was that you can only select two scan rates, 50ms and 5ms but overall it does work, it’s free and enables you to use your PC or laptop as a basic oscilloscope. You can down load the software for Winscope v.2.51 here.

Scope

Scope is a more sophisticated soundcard oscilloscope program. Its available to use free for private and non-commercial use but is not freeware. Scope V1.46 is the latest version and can be downloaded from the authors site Christian Zeitnitz here.

Scope will also run on Windows 10. It’s also very easy to operate, this time there are simulated buttons and control knobs, it looks like a traditional oscilloscope. Again the bandwidth is obviously limited because of the soundcard but will be fine for most audio use, going from about 20 Hz to about 20 KHz. It has run and stop push buttons and the scan rate is fully variable unlike Winscope. It will also run on full screen, something else Winscope can’t do.

You can use two channels if your soundcard supports it. They have a clear green and red colour to avoid any confusion. The Scope software has quite sophisticated triggering options as well as XY graph and frequency functions if you want to look at something a little more complex.

It also features a dual signal generator that can produce different wave forms and fully vary the frequency from 10 Hz to 10 KHZ. This can also be swept and you can detach it and show it in another window if you’re making adjustments, so you don’t have to keep swapping between modes.

Zelscope

Another oscilloscope program for Windows. With this software you get a fourteen day trial period then you have to buy it if you want to continue using it. It’s pretty cheap though at $9.95. Unfortunately, although the program installed on Windows 10, when I tried to run it I got the message “For security purposes, this program will not run while system debuggers are active. Please remove or disable the system debugger before trying to run this program again.”

Without any obvious ways to run or progress I uninstalled the program. That’s as far as I got unfortunately.

Best PC oscilloscope software

There are a few other programs for turning your PC or laptop into an oscilloscope such as Cobracom oscilloscope and xoscillo that I haven’t fully had time to take a look at but to be honest there’s only so much that a soundcard oscilloscope will be able to do because of the limitations of the audio card. It means your only ever going to get a limited bandwidth and given how good the Scope V1.46 software is I’m happy to use that. It does everything I could really expect free PC oscilloscope software to do and a bit more besides.
