Open Serial Oscilloscope Download

I've installed Proteus 8 and began to work with it. I've built a primitive circuit with oscilloscope. At first time visualization window (with graph of signal) was being got. I closed this window and stopped the simulation. But in the next time this window didn't open.

I try to solve this problem with the help of Google and found the answer: "You must to click right button of mouse at oscilloscope and find "Digital Oscilloscope" and problem will be solved". But it actually works in another versions of Proteus. I didn't find this in Proteus 8.

In order to show again the closed oscilloscope window start the simulation, then click pause and open the debug menu. From there click the oscilloscope option and the oscilloscope window will appear.

You can then resume or stop and restart the simulation and the window will be visible. The same stands for any other closed debug window.

Using the Reset Debug Popup Windows option in the debug menu (enabled only when the simulation is stopped) has a similar effect but the difference is that it will show all closed windows while with the way I describe you can show the selected windows only.

ThunderScope is the first oscilloscope designed for Thunderbolt, allowing real time sample data to be streamed to your computer at speeds exceeding 1 GB/s. By leveraging the powerful processing capabilities of modern devices this design removes all the limitations of traditional oscilloscopes.

ThunderScope is also open source, so you have complete control of the data from the moment it is sampled. You can easily add your own custom features and benefit from new features built by the community.

The Tektronix OpenChoice Desktop software may be able to open the .isf and .wfm file depending on the model of oscilloscope that it was captured from. Check the release notes of the latest version of OpenChoice Desktop to see if your model scope is supported.

If you are not able to open the .wfm file with TekScope or OpenChoice Desktop, you may try to use a waveform converter utility program. See this FAQ for details on different waveform conversion utilities.

Go in the elevator. Flip the switch to UP. Exit the elevator to the tower. The tower has similar setup like other rooms. Find the power generator and adjust the connectors so the generator can start working. Turn the power switch to power up the observatory. Follow the electrical wire to the device on a tripod. Flip four switches and press the diamond button in the middle. The oscilloscope is broken. Pick up a screwdriver next to the oscilloscope.

Exit study room. Go back to the library. Use the elevator to go back to the tower. Open the panel on oscilloscope. Insert electrical component. Adjust the frequency so the green waves align with the black waves. The device on tripod will start working. You will be taken to the observatory.

The sigrok project aims at creating a portable, cross-platform, Free/Libre/Open-Source signal analysis software suite that supports various device types (e.g. logic analyzers, oscilloscopes, and many more).

Another thing that has yet to be integrated is an extended timebase that would allow you to capture longer sweeps. The first prototype is limited to sweeps of 10 ns, and while this is probably OK for many uses of a 6 GHz sampling oscilloscope, longer sweeps are sometimes very useful.

A word of caution: don't get too excited about this project until you know the difference between a sampling oscilloscope and a real-time oscilloscope: they're vastly different beasts, suited to different purposes, and behave in different ways. The ubiquity of cheap, real-time, (but low-bandwidth) digitizing scopes has created expectations that sampling scopes, or even analog scopes, can't meet. For an introduction, you can check out this article on ElectronicDesign.

It will be open-sourced, but I'm not posting the design files for the first prototype, because it's lacking too many things to be practical. If someone really wants to get a crack at the design files, ping me. The schematic and and board layout are in PDFs in the files section of the project for reference.

An oscilloscope is for looking at waveforms, so I started digging around for some stuff to look at. I found the 74AUC gated ring oscillator I had discussed on another project, and fired it up. 74AUC logic outputs have interesting steps in their transitions because of their unique 3-stage output driver structure optimized for 50-65 Ohm transmission lines.

For reference, here's the waveform as I captured it on a slow 1 GHz oscilloscope back in December. With a 1 GHz scope, the finer details of the transitions are blurred, and you can't see evidence of the 3-stage output drivers at all.

I have been told that at a certain oscilloscope manufacturer the first measurement with a new scope design is sometimes called "green on screen," like "first light" for telescopes and "first ping" for routers. This is the first waveform captured with the first prototype sampler:

The basic idea is to capture a single comparison result at each trigger. So, at the first trigger, you ask if the waveform at the trigger time is above or below a specific voltage. By trying a number of voltages, and recording the greater/less-than answers from the comparator, you can eventually deduce the voltage at that time. If you've ever explored successive-approximation analog-to-digital converters, you'll recognize a similar process. Unfortunately, the binary search used in most SAR ADCs is sensitive to noise, and is not always suitable for a sampling oscilloscope. There are a number of alternative approaches, and a small body of literature on research in this area. The simplest (and perhaps slowest) method is just to try all possible voltages. It's dumb, but it works, and is resilient in the presence of noise.

Another key component is the Si53360 clock distribution buffer. This CMOS part handles the clock and trigger timing while adding very little jitter (120 fs RMS). The two inputs to the clock fanout part allow the sampler to be triggered from an external source, or to generate its own sampling clock. This functionality directly parallels the Tektronix 11801 sampling oscilloscope. It works pretty well.

Great project.

I enjoy him a lot.

I'm thinking of trying these comparators.

You gave the scheme and the board.

I have a question, with what software can this oscilloscope be observed?

What product board did you design it for?

Thanks in advance.

The Earth People Technology DSO 100M development system is a fully functional USB Digital Storage Oscilloscope. It was designed to be open, flexible and easy to modify. This Open Source Development System allows the user to understand the basics of the typical DSO. All source code along with compiled projects are made available. The user can modify the Verilog code in the FPGA as well as the C# project known as the UnoProlyzer.

The DSO 100M utilizes the UnoProLyzer application to control and display the oscilloscope results on a Windows PC. The UnoProLyzer is a C# Windows application. This means it is an event driven application. Any event such as a button press or timer expiring will initiate a function in the application. The application communicates with the FPGA Code via EndTerms. It sets up the buttons, timers and display in the Window. The applications waits in idle for the user to initiate an event, or an automatic event initiation.

The DSO is easily programmed from the Quartus Lite Software. Just plug a Micro B USB cable from an open Port on the PC to the Connector on the DSO 100M and load the drivers. A proprietary *.dll from EPT allows the DSO 100M Configuration Flash to be programmed directly from Quartus.

Loading a waveform or screenshot into WaveStudio can be performed in one of two ways, either offline or connected to the oscilloscope. When offline, simply open a trace file from a USB stick or e-mail attachment from the oscilloscope's save waveform function.

WaveStudio makes it easy to document your work, whether the oscilloscope is next to you or is many miles away. Save LabNotebook traces for future analysis, or save the screenshot as a .bmp, .jpg, .png, or .tif. Traces can be saved in binary or text formats.

Once the Scope instrument opens, the window contains the data plot (1.) showing captured data, the configuration panel (2.) to right of the plot, and the control toolbar (3.) at the top of the window.

Note: When using BNC Probes, make sure to take note of the probes' bandwidth. When probes are used with an oscilloscope, the achievable bandwidth is limited by both the probes and by the scope. For example, using 1 MHz probes will limit the bandwidth to 1 MHz, even if that is below the Test and Measurement device's specified maximum.

Connect a BNC oscilloscope probe to the Analog Discovery Pro's Oscilloscope Channel 1 connector and a set of BNC minigrabbers to its Wavegen Out Channel 1 connector. Connect these together, as pictured, to form a loopback circuit. Check the input probe's attenuation factor, as it will be used later to set up the software. 17dc91bb1f
