content: Hello.I'm currently trying and failing to capture a BPSK waveform so I can decode it manually.I'm using the DS1054Z (Software upgraded all options ect)I used the record mode and captured the waveform. I would like to export this waveform to the PC so I can view the entire waveform and scroll through it.I'm unable to do this, it's really frustratingcan someone tell me how to do this? many thanks in advance.I attached the a screenshot of the waveform (208 parts) I would like to export.(I'm also unable to set the horizontal time scale to a custom value so I can view 1 symbol on every screen, but I believe this is not possible. else decoding on the scope itself would be possible)

content: And I wrote a little tool that imports the waveform to LTspice (and WFM viewer)Haven't used it last couple years though.The link is below in my signature.

content: Hi Peter,I downloaded the program and changed the USB driver. The program works perfectly. I like it much better than the rigol software (ultrascope).still I can only export a single wave from the recoring each time, is it also posible to export the whole recording to a single file?

content: Haven't decided yet, I will try the following things.using gnu octave to plot the whole signal (combined csv files).Or maybe I will use the program in combination with Auto Hot Key to create a single image of the waveform and scroll trough it easilly.Maybe gnu radio for automatic BPSK decoding (but I haven't used it before) and I'm not sure if the signal is properly modulated and can be decoded this way, I found some inconsistencies in the signal.The decoder is working fine with the old hardware and won't be modified, so I have to recreate the signal to make it work.The signal is captured from a legacy product, no documentation so reverse engineering the thing. I've created new hardware and firmware for this product, but the PSK signal I generate does not match with the legacy product and thus the receiver can't decode it. So I needed a way of comparing the waveforms easily. Now with the waveforms on my PC I can continue

I used python "RigolWFM" to plat the wfm file. same result;I also loaded the wfm on the scope itself. same result.Does anybody know how to export the complete recording to a wfm file? or is it not possible?On my DS1054Z scope I create a recording (61 of the 5000 slots filled with the data), next I go to the storage menu and store the wfm file to the USB.but this wfm file does not contain the recorded data.

content: Quote from: littleboot on November 18, 2020, 11:09:35 amyour wfm contains exactly what is shown in your screenshot and on my screen as well, only some noises but no sine signal (i also checked the file in hex editor) iirc we dont have problem saving wfm of all captured data. not sure why your DSO only saved partial data. maybe because its the "recording" function? (i never tried that feature) the black horizontal bar with green text just above the signal display. can you disable that and do normal triggering and save to wfm again?

content: Quote from: Mechatrommer on November 18, 2020, 05:10:16 pmvisaDSO works as expected. The recording mode was causing the issue, when using this mode and exporting the wfm file. The waveform frame on the screen is actually not saved to the file.
