1142 error-

I have the same issue as the user of the OLD FORUM:&#160;<br> <br> https://forum.tek.com/viewtopic.php?t=142847<br> &#160; <h3><a href="https://forum.tek.com/viewtopic.php?t=142847#p290225">Line frequency detection failure</a></h3> <ul> <li><a href="https://forum.tek.com/posting.php?mode=quote&amp;f=263&amp;p=290225" title="Reply with quote">Quote</a></li> </ul> <p><a href="https://forum.tek.com/viewtopic.php?p=290225#p290225" title=Post>Post</a>&#160;by&#160;<strong><a href="https://forum.tek.com/memberlist.php?mode=viewprofile&amp;u=523739">ksalamon@irb.hr</a></strong>&#160;»&#160;November 19th, 2021, 2:57 am</p> Hello,<br> I'm using the 2450 smu.<br> When the instrument is powered on, it posts Error message regarding line frequency: &quot;Error:1142, Line frequency detection failure.&quot;<br> TSP command 'localnode.linefreq' reads frequency=0.<br> Why is it so, and how can I fix it?<br> I wonder does this problem influences the measurement integration time? Here in lab I have 50 Hz, so if I set NPLC=1, does the measurement integration time is 20 ms?<br> <br> Thank you.<br> Kreso Salamon<br> <br> --<br> long time ago, but my was sold as NEW returned device form a ebay seller in Netherlands. But the sticker is from kroatia, same as the old thread name... ANYBODY here knows who it was -- I just returned the instrument to the seller....&#160;<br> <br> there was a sticker 48023 from the previous owner....&#160;<br> <br> &#160;

Hello,<br> <br> I apologize, but we are unable to verify the previous poster's unit and related information without the serial number of the unit associated with that post.<br> Additionally, Tektronix is unable to share purchase and identifying information related to other customers without their consent.<br> <br> If you believe you were sold a product in error by a third party (i.e. via ebay), you would need to return the product to that individual or discuss proper action to address your concerns with that individual.<br> <br> I understand that you have returned the instrument to the seller. If you purchase a used or new item via an independent seller, rather than direct through Tektronix or through a licenses distributor, we cannot guarantee the functionality or validity of such sales/product and can only recommend the instrument be evaluated by our Service Center to address any operational concerns/malfunction.<br> <br> I apologize that we cannot provide more assistance related to this issue.
