<p>Hi Luis,</p> <p></p> <p>I am no expert on Windows (I'm much more familiar with the UNIX/Linux user system), but I don't believe it's possible to &quot;raise a user to administrator&quot;. Instead what's going on when you &quot;run as administrator&quot; is that both your regular user account and your admin account are logged in at the same time. My suggestion is to log off all users and then login only to the admin account and attempting to run it from there.</p> <p></p> <p>NI VISA and TekVISA have been known to not work well together in the past, so I would suggest uninstalling them both and installing TekVISA again.</p>

Hi Vincent,<br> <br> I apologize, the TDS7054 does indeed save SPC to disk, not NVRAM.<br> This suggests that it's somehow not able to write to disk? I would try saving files to disk and see if that works.<br> <br> I am not quite sure what you mean by &quot;data I have to write by console port&quot;, could you clarify that?

Hi Luis,<br> <br> TekVISA is only meant to have one instance running at a time. I wonder if when you try to run it as admin there's already a non-admin instance running, so it doesn't allow you to open a new instance as admin? You could try logging out of your non-admin account and logging only into the admin account to see if that solves it.<br> <br> Another possibility is that the admin install isn't working properly. I would suggest uninstalling TekVISA entirely and installing it only in the admin account.

Hi Carrie,<br> <br> In Basic mode, change it from Continuous to Burst and set the number of cycles to 1.

Hi Howard,<br> <br> The &quot;Run&quot; button is a physical push button in the &quot;Advanced Mode&quot; cluster on the front panel.<br> <br> For Basic mode (non sequential mode), there's no Run/Stop command, the waveform is always playing (Sweep and Burst are an exception, those require an internal or external sweep to start).

Hi Howard,<br> <br> I think the problem here is how you're enabling the output.<br> Whenever the instrument is in &quot;Run&quot; mode, the waveform is playing and the clock is advancing. Enabling/disabling channel 1 or 2 does not stop or start the waveform, it simply disconnects the ADC from the output (you can hear the relay clicking).<br> <br> So the solution is to press Run when you want to start or stop the waveform.<br> In SCPI commands this is <code><span class=markedContent id=page220R_mcid0><span dir=ltr role=presentation style="font-family:sans-serif;">SEQControl:<span class="highlight appended">RUN</span></span></span></code> and <code><span class=markedContent id=page220R_mcid16><span dir=ltr role=presentation style="font-family:sans-serif;">SEQControl:STOP.</span></span></code>

Hi Barry,<br> <br> The digital signal upgrade package is &quot;SUP2-MSO&quot;, it includes the software license and a P6316 digital probe.<br> <br> You can contact our sales team by emailing buy@tektronix.com.<br> <br> <br> &#160;

<p>Hi Vincent,</p> <p></p> <p>The battery for the NVRAM is inside a DIP32 package (DS1245Y), are you saying you replaced this?</p> <p>There will also be a normal coin cell type battery on the mainboard, usually for the real time clock, but that is another system and not related to the NVRAM where SPC data might be stored.</p>

Hi Marianne,<br> <br> The RSA API gives you direct access to the samples from the RSA ADC, it requires significant post-processing work to then transform that into a dBm measurement.<br> Additionally, the RSA API is unsupported and only meant for very specific cases where it's needed (Linux platforms or high transfer rate applications).<br> <br> Instead I would suggest you use the SignalVu-PC programming interface: <a href="https://www.tek.com/en/manual/spectrum-analyzer/signalvu-pc-vector-signal-analysis-software-programmer-manual-rsa306">https://www.tek.com/en/manual/spectrum-analyzer/signalvu-pc-vector-signal-analysis-software-programmer-manual-rsa306</a><br> This interface allows you to get the spectrum trace with just one SCPI command, with all the processing being handled by the SignalVu-PC application.<br> &#160;

Hi Vincent,<br> <br> I can't quite confirm that the SPC data is saved in NVRAM, but that's what it sounds like from your symptoms.<br> The TDS7000 (and several other models) use an NVRAM chip with an internal battery which can go bad after many years. In the case of the TDS7000, this chip is <tt>DS1245Y</tt>.<br> <br> Replacement and even some repairs/modifications of these chips are not unheard of.
