Hi,

is there a (freeware) program available for computer, which would allow viewing waveforms recorded by InfiniiVision series oscilloscopes? I have hundreds of waveforms and I would like to quickly browse through them. The data is recorded in binary format and each .bin file contains several segments. There is an option of first converting .bin files to .csv files and then plot the data (see thread How to convert binary (.bin file) to ascii file?). However, this takes quite some time and space on a hard drive. I would prefer to first see all the waveforms and then select only few for further analysis.

Thanks for the help,

Matjaz

Hi Matjaz,

With the program that saves .bin to ascii, instead of saving to ascii, you can plot, say, 500 evenly-spaced samples from each waveform to a SVG file using Matplotlib. Then, viewing extra large icons in the Windows 10 File Explorer you can browse the SVG waveform plots. It's still going to take some time, but the SVG plot files should be pretty small, like 30KB each.

Best Regards,
Pat

  Hi Pat,
  
  that's good idea. Do you have script for converting .bin to .svg?

      Thanks Pat, it works great. I have two more requests. Could you write a script with an option of plotting only data from one of the channels? I want to browse only through waveforms from channel 2. Also, could you make a script, which would convert all .bin files in the directory instead of specifying each file individually.
      Thanks,
      Matjaz

        Hi Matjaz,
        
        Attached is a script with the two additional modifications. The --labels option lets you list the waveform labels you want to process, for example, --labels 2 D0-D7.

        Thanks Pat for the new script. I have one more requests. I would like to compare all graphs on the same y-scale. Is it possible to add an option in the command line or set values in the script so all graphs would be plotted for the same y values (e.g. from -20 V to +150 V)?

Hi Matjaz,

I don't have InfiniiVision oscilloscope, but do you have some samples of .bin file. I will check if it's possible to do something with that. What is the model number of your oscilloscope?

  Hi Yves,
  
  in the attachment is an example of the .bin file (2020-01-09_11.bin). All four channels contain signal and the file has 20 segments (i.e., there are 20 sequential waveforms recorded for each channel).

    Hi, I know you already have a solution for reading files, but just out of curiosity, can you tell me if the data on the 2 images make sense. These are the data extracted from the bin file that you provided to me.

      Hi Yves,
      yes, the plotted data is correct. I really like the second representation with all the segments (pulses) in one graph (4CHallSEG.PNG) since the data is represented on the same y-scale. How did you convert the .bin file data? Can you please share the code? I also prefer .png format over .svg format.
      Thanks,
      Matjaz

        Hi Matjaz, to extract DATA, I used information on user manual page 385 to 391. It's not very complicated, but there are many formats and parameters. I will send you the program (vb.net 2019) and code maybe this week-end.
        
        Few pictures below,
        picture 1: 2 channel (voltage and current on same Y scale from -20 to 150), one segment
        picture 2: all segments
        Picture 3: all overlapped segments. With persistence button activated, it's possible to overlap many file
        Picture 4: all overlapped segments with white background
        
        But before finishing this program, which is specific to your requests, I have a few questions:
        You mentioned that you wanted a scale from -20 to 150, is this correct as a first try, or does it have to be adjustable?
        I display on 10 vertical divisions, would you prefer on 8 divisions?
        Here I display channel 1 and 2, ie the voltage and the current on the same vertical scale, is the channel to be displayed only CH1 or CH1 and CH2?
        If CH1 and CH2 must be displayed, the current display order is CH2 in the foreground (background) and CH1 in overprint, is this correct for you?
        Need to display other data or is it correct as is?
        
        If you had a few more files, it would be nice to be able to test the program.
        
        Regards
        Yves

        Hi Yves,
        thanks for your effort. I prefer presentation on picture 2 since it shows all segments in sequence (black background is better). Problem with the picture 3 and 4 is that I cannot distinguish between the individual segments. Such presentation would be good if you can create separate .png files for each segment or plot them in a single .png file with different colors for each segment (and include the label).
        Regarding the scale, I would need it to be adjustable (-20 to 150 was just an example).
        Number of vertical divisions is not very important, both 8 or 10 are fine.
        I mainly need to visualize data from Ch2. Ch1 could be also useful but then its y-scale should be on the other side of the graph (e.g., left scale for Ch1 should go from +50 V to -600 V, while the right scale for Ch2 should go from -20 to 150). Both y-scales should be adjustable. The Ch2 should be in the foreground and Ch1 in the background.
        Channels 3 and 4 are not important and you don't need to plot them (plus they have very different y-scales so it is difficult to put them on the same graph).
        I would like to convert hundreds of .bin files to .png so it would be great if the script could go through all the files in the directory.
        I am attaching three more .bin files.
        Thank you,
        Matjaz

        Hi Matjazz,
        
        A- open File
        B- Save picture (will be saved in same directory that file loaded, automatic name example : DSOX3034T_2020-02-16_21_37
        C- Range for each channel, yellow (CH2 current) on left and blue (CH1 voltage on right). When all segments view is selected, alterned yellow and green trace to show individual segment.
        D- Display alla segments on the screen
        E- One segment at time, use arrow to see individual segment
        F- Create automatically a png file for each segment of all files in selected directory: with openFile button, select any file (allows to select the folder) and push CreatePNGfiles button. All *.bin valid file will be processed. I've done a test with the 4 files you provided me: 40 png files were created in 2.2sec, around 95k per file. The speed of execution depends on the performance of the PC and the disk drive. Example of name of file: 2020-01-09_11_seg_18.png (name of bin file + _seg_X.png, X is segment number)
        G- vertical coordinates (with mouse move)
        H- time evaluation to process a file or to create all png files in selected directory
        I- With one segment view, you have horizontal coordinates (with mouse move). Two horizontal coordinates: one for relative in the segment, and the second for elapsed time from first trig. In this example below, elapsed time was 0.06 sec between first Trig and trig of segment #7. Trig position for each segment is available in bin file.
        
        Just to test this software customized for you and please send me feedback. I tested on 1280x1024, 1920x1080 and 2560x1440 monitors

        Wow, amazing! Thank you Yves! This is exactly what I need. It works great.
        There are only few issues.
        B – On my PC there is some problem with SavePIC option. DSOX3034T.application crashes (and Windows Explorer if I ignore the error) when I try to save the allSegmens data. See the error message in the attached file. I'd be great if I could save the allSegmens.png file.
        E - Would it be possible, in the per_segment view, to use keyboard arrows to move up and down the segments?
        When I resize the window of the program, data does not scale up or down, it just cuts it. If there is no easy fix, I can live with it.
        Thank you very much for the program. It really makes my work much easier :-)

        Hi Matjazz,
        
        For point B: I tested on 2 PCs and 3 different size screens, but the 2 PCs were under Windows 10, I just tried with my laptop under Windows 8.1 and the display is slightly incorrect at the top, I will correct this problem.
        
        To make sure I understand correctly, does the backup of oneSegments files work correctly? If yes, you want this allSegment image to be included in this list automatically too?
        
        In addition I cannot reproduce your backup problem for the AllSegment case, can you give me some information, such as the resolution of your screen, under which version of Windows is your PC. I will try to understand the error file that you provided me, because I am a beginner in programming, this is not my job, I am RF & Analog Designer sr., I do a little programming for control of my Instruments.
        
        For point E, I had thought about it, lack of time yesterday. I'm going to assign the arrow keys, it's quite simple to do.
        
        Normally, there is no resize on this form, I am surprised that you could do it, the window is normally maximized. So the behavior you noticed is normal in this case. But do you really need this function, because there is so much detail about capturing the data, that closing the window will make the data hard to see I imagine. For traces it is quite simple because each data point occupies a pixel, while a character is linked to several pixels, it is more difficult (height and width and reference point). I already did this in another program, I'll take a look.
        
        Glad to see it could help you. I should probably be able to give you an answer today.

        Hi, I've done modifications for display, include ALLsegments picture in PNG batch files, Windows sizeable, add control via 4 arrow KEY. I've tested on different PC and Display monitor, under Windows 7,8.1 and 10 and didn't found any problem with save png files...I will try again tomorrow.
        
        LEFTarrow: count -1 segment
        RIGHT arrow count +1 segment
        UP arrow, go to ALL segment screen

        Yves, thank you very much. Your program does everything I hoped for. As far as I'm concerned, you are an expert programmer :-). The arrows and resizing works perfectly. There is still an issue with the SavePIC function but it doesn't really matter as program now exports .png file for allSeg view.
        Thank you again, you really helped me a lot. I hope some day I can return the favor.
        
        All the best,

        Hi Yves, I found one important issue when exporting .png files. If there are more .bin files in the directory then the program exports .png(s) only for the open file while for other .bin files the export doesn't work. The program overwrites the .png(s) of other files with the png(s) of the first file (though the naming of these files is different). See attached png files for three bin files from previous post. I guess the program just runs over the open .bin file and exports the same png(s) files for all other bin files in the directory. The same problem is for allSeg plot.

        Hi Yves,
        I am very satisfied with your program but I realized there are few things that I would like to modify. How difficult it is to implement in the program the following options:
        thickness and color of waveform lines
        number of divisions in x- and y-direction
        color and size of fonts for y-axis
        dimensions of the window
        color of the background (I prefer black color but I might need to change to white)
        These are not essential things but I would be very grateful if you could implement them (as options) or give me the source code and tell me where to make the necessary changes.
        Thank you,
        Matjaz

        Hi,
        
        Some requests would be easy to make, but others are more complex since it was not intended to make them variable. For the graph, I did not use the chart object, it is simply a bmp drawing translated into png, I have programmed my graticule and the number of division as well as the surface of the graph...
        When you say "dimensions of the window", what do you mean, because right now, the window is resizeable.

        Ok, I understand, you make conversion from bmp to png. The dimensions of the window are not very important because I can manually resize the window (and then export such view to png file) but it would be nice to have the other options if possible
        thickness and color of waveform lines
        number of divisions in x- and y-direction
        color and size of fonts for y-axis or maybe have an option to turn it off (or make the same color as background)
        color of the background
        As you know, I can convert data to csv files and then plot individual graphs for CH1 and CH2 for each segment. However, this takes a while that's why I really like your program, which allows me to plot things very fast.

        Hi Matjazz,
        
        Finally I found the problem with the last version of software. I added the functions you wanted and also the dimension of the form which is saved when the program is closed as well as all the configurable variables.
        
        Axis labels are rounded up to 3 fractional digits max, based on the volt / div scale.
        scale 1.334 v/div => max 3 fractionnal digits
        scale 11.334 v/div => max 2 fractionnal digits
        scale 111.334 v/div => max 1 fractionnal digits
        scale 1111.334 v/div => no fractionnal digits
