I would like to continuously save traces after each trigger for a period of minutes or more. I have seen suggestions to use the the tekscope utility, but this does not seem to support the required scope time resolution over longer periods (~1 ms sweep time).<br> <br> Does anyone know the limitations (bandwidth) of saving over a USB vs to a connected disk? Are there any resources available for&#160; this type of measurement (existing code or applications)?<br> <br> Thanks for any help<br> Michael

Hi Michael,<br> <br> I do not see the limitation you are talking, <a href="https://forum.tek.com/viewtopic.php?t=140451">TekScope Utility</a> was able to data log waveforms over 1 ms at 50 GS/s, although slowly due to slow connection speeds.<br> <br> If the connection speeds are a limitation for you, then saving to &quot;disk&quot; (the instrument's SSD) will be significantly faster than transferring through USB. If you would like to save to a networked SSD then that's also possible and still significantly faster than USB transfers.<br> <br> In terms of resources for remote control programming, your best friend will be the <a href="https://www.tek.com/en/sitewide-content/manuals/4/5/6/4-5-6-series-mso-programmer-manual">programmer's manual.</a>

Hi Alfonso,<br> <br> Thanks for the reply. I am working with another student, so I may have misunderstood their problem with Tekscope. What exactly did you mean by 'slowly' in this context. Is it that it can log a single trace, but needs a longer time to transfer data between traces?<br> <br> I was hoping to not have to start from scratch on the program, since this seems like a common task, however, it does look like everything is there in the programming manual.<br> <br> Regards,<br> Michael

<div class="linenums prettyprint">Hi Michael,</div> <p><br> Just to be clear, <a href="https://www.tek.com/en/products/software/tekscope-pc-analysis-software">TekScope</a> and <a href="https://forum.tek.com/viewtopic.php?t=140451">TekScope Utility</a> are two completely different softwares.<br> <br> Yes, TekScope Utility was slow because at 50 GS/s for a 1 ms long acquisition, results in 50 Mpts, which is a pretty long waveform to transfer. If you require less points than that then you will see a significant speedup.<br> <br> I have included an example of downloading waveform data with Python3 from an MSO2/4/5/6.</p>

Hi,<br> <br> Thanks for the clarification. I was referring to Tekscope Utility.<br> <br> I had a look at the example; do you happen to have another that saves to disk instead of using 'curve?' for file transfer? Otherwise this is a helpful starting point.<br> <br> &#160;

<p>Hi Michael,</p> <p></p> <p>I do not have a specific example, but I believe you would use the <code>save</code>&#160; and <code>saveon</code> group of commands, listed on page 2-92 and 2-93.&#160;</p>
