Hi,<br> <br> I was wondering if there has been a fix to read out the measurement for the channel power?&nbsp; I am attempting to record channel power remotely using SCPI, but I am receiving incorrect measurements reported back.<br> <br> - I am measuring the power of Channel 8 using Spectrum View on Measurement 1<br> - The badge is present on the screen, showing ~ -100dBm<br> - Command sent: &lt;code&gt; MEASU:MEAS1:RESU:CURR:MAX? &lt;\code&gt;<br> - Response to Query: "9.91E+37"<br> <br> Any help would be appreciated!

Afonso,

The FW rev update was the issue.  As soon as I updated the firmware, the option to change between "Chx Analog" and "Chx SV_Normal" was available.  Thank you so much for your help!

After reading more documentation, I see a note that states, "If the menu shows tabs other than Standard, then optional measurement types have been installed on the instrument.  Select a tab to show the measurements for that option." 

Could this be the issue?  Are there add-ons that I would need to download in order to be able to view Analog, SV_Normal, Normal, Max Hold, and so on from the Measurements Source List?

Thanks again for the help.  I'm just not seeing a "Source" menu / hard button / soft button / etc. Sorry for the confusion.  I'm sure if it was a snake it would bite me...

Thanks so much for the response, Afonso!  When you say "change the source to Ch_1_SV_Normal", are you referring to changing the source in the measurement window?  Or somewhere else?  The only options I can see when I open the measurement window is Ch1-Ch8.  Thanks again.

I am attempting to measure the amplitude at a specific frequency in Spectrum View on an MSO58.  Specifically I would like to record this information via SCPI commands, so the on-screen banners alongside the markers and/or cursors which display values is not of help to me (unless those values can be retrieved via SCPI commands).  This seems like it should be very easy to add, but I cannot figure it out.  If I choose to add a new measurement, the spectrum view is not an option, and so the amplitude that is reported on the measurement window is referencing the time domain signal.  I have attempted multiple different methods to gather this information including the Spectrum View Marker, Cursors set to the desired frequency, Math functions, etc., but none have worked.

I have attached an image of the signal for reference.  The frequency of interest is 25kHz.  Any help would be greatly appreciated!
