The DP832A version. Never calibrated, hesitant to do that myself.&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;Reminds me that my Keithley DMM is due for calibration. That one I want to bring to Welectron in Germany - always a good excuse for a daytrip.&amp;nbsp; When the curfew is over ...&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;&lt;em&gt;edit:&lt;/em&gt;&lt;/p&gt;&lt;blockquote class="jive-quote"&gt;&lt;span&gt;My previous experience with Rigol&amp;#39;s test equipment software and remote control was not good, they were unstable and not usable at all. I was surprised to find that now the TCP/IP link worked very well.&lt;/span&gt;&lt;/blockquote&gt;&lt;p&gt;&lt;span&gt;What issues do you have? Software incompatibility?&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span&gt; I&amp;#39;m using them with TCP/IP too (PSU, oscilloscope) and they behave OK.&lt;/span&gt;&lt;/p&gt;&lt;img src="https://community.element14.com/aggbug?PostID=9124&amp;AppID=255&amp;AppType=Weblog&amp;ContentType=0" width="1" height="1"&gt;</description></item></channel></rss>
