CSV Resoltuion

<p>Using a MSO64 I'm trying&#160;<span style="font-size:11pt;"><span style="font-family:Calibri,sans-serif;">to accurately measure all periods of a 1s waveform. I’ve set the horizontal resolution to 4ns for accuracy and I can measure 1s of the waveform no problem with 250Mpts.</span></span><br> <span style="font-size:11.0pt;"><span style="font-family:&quot;Calibri&quot;,sans-serif;">I can generate a time trend of the data and this shows all measured periods of the wave form, see attached.</span></span></p> <span style="font-size:11pt;"><span style="font-family:Calibri,sans-serif;">This is exactly the data I want. However when I export this to CSV I get 59 entries as expected but the vertical resolution is too low. All samples show 0.0166667 seconds even through the display on the MSO is much higher resolution.</span></span><br> <span style="font-size:11.0pt;"><span style="font-family:&quot;Calibri&quot;,sans-serif;">Start of the CSV is shown below:</span></span><br> <span style="font-size:11pt;"><span style="font-family:Calibri,sans-serif;"><span style="color:#002060;">X: (s),Y: (s)</span></span></span><br> <span style="font-size:11pt;"><span style="font-family:Calibri,sans-serif;"><span style="color:#002060;">-0.490668,0.0166667</span></span></span><br> <span style="font-size:11pt;"><span style="font-family:Calibri,sans-serif;"><span style="color:#002060;">-0.474002,0.0166667</span></span></span><br> <span style="font-size:11pt;"><span style="font-family:Calibri,sans-serif;"><span style="color:#002060;">-0.457335,0.0166667</span></span></span><br> <span style="font-size:11pt;"><span style="font-family:Calibri,sans-serif;"><span style="color:#002060;">-0.440668,0.0166667</span></span></span><br> <span style="font-size:11pt;"><span style="font-family:Calibri,sans-serif;"><span style="color:#002060;">-0.424002,0.0166667</span></span></span><br> <span style="font-size:11pt;"><span style="font-family:Calibri,sans-serif;"><span style="color:#002060;">-0.407335,0.0166667</span></span></span><br> <span style="font-size:11pt;"><span style="font-family:Calibri,sans-serif;"><span style="color:#002060;">-0.390668,0.0166667</span></span></span><br> <span style="font-size:11pt;"><span style="font-family:Calibri,sans-serif;"><span style="color:#002060;">-0.374001,0.0166667</span></span></span><br> <span style="font-size:11pt;"><span style="font-family:Calibri,sans-serif;"><span style="color:#002060;">-0.357335,0.0166667</span></span></span><br> <span style="font-size:11pt;"><span style="font-family:Calibri,sans-serif;"><span style="color:#002060;">-0.340668,0.0166667</span></span></span><br> <br> <span style="font-size:11pt;"><span style="font-family:Calibri,sans-serif;">How can I increase the resolution of the CSV file to be useful? I can’t find any settings in the device to support changing this.<br> Ideally I wound like 14 significant digits, not 6.&#160;</span></span><br> <br> &#160;

<p>Hi Erik,<br> <br> By default Excel does not show all the digits for very long numbers, you have to manually increase the displayed digits. I've attached a picture of the toolbar button where this is usually done.</p> <p></p> <p>If that doesn't solve it then I would ask if you could attach the .csv file here so I could examine it more closely.</p>

This is not the problem, The text I posted is the raw csv output, not processes in excel.<br> CSV file is attached.&#160;<br> <br> &#160;

I managed to get the python script running with some modification using fast frame.<br> It's a little disappointing that I need to hack into a very expensive device to get the data out that I need. It should support the correct resolutions and outputs natively without spending hours install tools and learning the VISA interface.<br> Also disappointing that using Tektronix support ticket system yielded no reply after two weeks.<br> &#160;
