Rigol had released the V1.15 at 12/02/2015 but removed them reasoned by some new problems - error message: "431 - intermediate frequency out of range" at the finish of the init of the dsa and just before the device is ready.
The noise-level seems to get more bad - about 30dB. I opend a ticket and they are quick in germany. They allways answer mostly the same day. 
Some other issues are in the remote operation. My device (HW 0.4) got a currious behavior around the hardcopy and SCPI command response time. As longer i work with the dsa, as less i able to reproduce them again - that thrills me.
Just keep in touch with it.

There is a "new kid on the block" contender coming out in "spectrum analyzer land".
This time from Siglent! Will be interesting to compare it against Rigol DSA815-TG :)

Jerry,
I just picked one of those BEAST (8568B) couple weeks ago and it also acts the same when the RBW is 10Hz and Freq counter on. With the RBW at 30Hz its not really noticeable unless I look for it. Guess I will see what my 8591E does when I turn on the counter.
On a cheery note, my brother who is very active with meteor scatter and EME (moonbounce) came down for a visit and we were messing around with my SA`s. He looked at the specs of the 815 and said we might be able to see some signals being reflected off the moon if theirs any "big guns" transmitting. To our surprise we were able to see couple signals on 2 meters !!!

Has ANYBODY heard back from Rigol yet ?

N8,funny you should mention EME.  I have a 22 element beam cut for 432Mhz SSB.  I belonged to a net years ago. I live on a sloping hill and noticed that as the moon rises this time of year the beam is pointing right at it and now that you mention it, I am going to hook it to my analyzer and see if there is anything there.  I recently added the 85685 RF preselector which has tracking filters and a 20dB preamp so this will be an interesting test.

DSA815 Update 00.01.15.01.00 dated 2016-01-22 is available at http://int.rigol.com/Support/SoftDownload/3
Under 'Product Series' select 'Spectrum Analyzer', then 'DSA815 Firmware_00.01.15.01.00'.
It is not yet available on the Rigol North American web site.

I don't know yet what it is proposed to fix, but we have been waiting a long time now for Rigol to fix the issues with the Tracking Generator.  Hopefully this release will help. . .

Well one issue with this release is that it saves .jpg screen captures "upside-down".  :palm:

Hi xrunner:
When you said: saves .jpg screen captures "upside -down", did you mean -> Prints them upside-down to a PictBridge printer?  I understand that the DSA815 can only save its screen to a USB thumb drive as a BMP file.  Have you discovered a way to save (not print) a .jpg file directly from the DSA815?

No, I mean it saves a .jpg upside-down to a USB thumb drive. That doesn't happen when you use .png or .bmp, just .jpg. I have confirmed this bug with another person I know who had a DSA815.

No, it can save it in three different type - .jpg, .bmp, and .png. Go to System, 3rd page, screenshots.

Thanks so much.  I don't know how I missed this capability.  I learned something from you and I'm grateful.  And it turns out that this capability was added in this new firmware 00.01.15.01.00.  Ted

Edit: Added ref. to this being new in 00.01.15.01.00 Firmware

Just curious. Why would you want to save the image as .jpg?
.png filesize is just as small (even smaller probably) and .png is lossless, at least I think the Rigol .png is.
.png Looks much better than the somewhat fuzzy compressed .jpg's

Yes, I also prefer the PNG file format and it is around half the size of the JPG.  The BMP and PNG files are not flipped over like the JPG is.  BUT, it does take the DSA815 a lot longer to save a .png file to USB.
Comparison of DSA815 File Size and Time to Save (Size/Time):  BMP ~1,125KB/~10sec.  JPG ~110KB/~5 sec.  PNG ~55KB/~23sec.

That long huh? 23 sec is crazy, and I can see no good reason for it to take that long. Well I know saving to USB takes a long time, so I always use a PC for screenshots. Using Ultra Sigma it only takes a few seconds for a screenshot and that ends up directly on the target PC anyway. (Ultra Sigma is next to useless for anything else though, the only other time I used it was for entering the magic codes  :))

Regarding the upside-down .jpg issue, I submitted a report to Rigol and got this back -

Quote

My name is Jason Chonko and I am an Applications Engineer at Rigol Technologies USA. Thank you for writing in.

Yes. You are correct.

I will submit a bug to our R&D department.

When they have fixed the issue, we will send you an email with the new firmware revision.

Thank you for choosing Rigol.

Sincerely,
Jason

Good news for those of us with the original DSA815 hardware versions:   DSA815 Firmware Update 00.01.15.01.00 dated 2016-01-22 (available at -> http://int.rigol.com/Support/SoftDownload/3w (Under 'Product Series' select 'Spectrum Analyzer', then 'DSA815 Firmware_00.01.15.01.00') has corrected the issue I reported here ->  https://www.eevblog.com/forum/testgear/rigol-dsa815-tg-10-mhz-issue/msg749136/#msg749136  And yes all of the options are still in place, and so far I haven't found any other issues.

Note: Edited above (in bold type) to add the full path to the new Firmware. From https://www.eevblog.com/forum/testgear/rigol-dsa815-tg-10-mhz-issue/msg851904/#msg851904

I'm happy, but how about those of you with the newer DSA815 hardware that 'Giorgio' (https://www.eevblog.com/forum/testgear/rigol-dsa815-tg-10-mhz-issue/msg723692/#msg723692) originally discovered and started this thread for.  Has this been fixed?

Thanks. Your link doesn't work for me, but it gets you into the system and then a few clicks will find the dsa815 firmware.

Agree, on the older hardware (which is what I have), the frequency shift is now gone when turning on the TG. So, that's good news for some of us. Just need to hear from folk with the newer hardware.

cheers,
george.

What???  My System menu only has 2 pages and I'm on FW 1.14.  What am I missing here?  I spent an embarrassing amount of time over the weekend trying to figure out how to save screen shots to JPG.   :-BROKE   :-//

Then please install the new version firmware to see if it shows up.  I also didn't know where to find it until I was pointed to it, so maybe it was just added in this new Firmware 1.15 (?).  Please let me know if you now find it.  Thank you.

Thanks!  You're right -- it is v1.15 only.  This is terrific!

I get the upside-down JPG with a white border too, but at least there is JPG finally!  PNG is very slow as stated above, but works perfectly and has better compression than JPG.

Weird results aren't just a Rigol problem:

We encountered a strange one with an IFR unit a couple of years ago.

The DUT had a PLL which would "let go" & revert to a default frequency about 30MHz higher than required.
This happened quite fast,& the IFR displayed it as a bunch of carriers,leading us to chase non-existent spurious oscillations.

We bought an "El Cheapo" SA,(which was an analog type) to constantly monitor 4 Transmitters (in an ISM application),& free up the IFR for other work.

The analog SA showed the PLL frequency change clearly.

Once the IFR's "bug" was known,we could work around it.

    Features of DSA815 Firmware Version 00.01.15.01.00, 12/25/2015:
1. Match performance/operation for newer hardware revision 05 / 07.
2. Add JPEG and PNG formats to picture save options.
3. Add CSV Correction file loading function.
4. Solved the problem of invalid data loading command.
5. Solved the problem of power average math result error.
6. Solved the problem of LAN communication connection errors.
7. Solved the problem of the amplitude of the output from the TG jumping at 10MHz.
8. Solved the problem with the peak frequency position changing after activating the TG.
9. Solved the problem with the EMI filter changing after calibration.
10. LAN library update, supports multi interface communication.
11. Solve the issue with garbled file names after opening 4 traces.

Edit:  Revised item 1. from '1.05' to '07 and 05'.

Very quick check on a "newer" unit suggests the 10MHz bug is gone. The trials appear to remain in place, but this is with the smarter version that resets the counter on power up via I2C, not the short. I'll leave that to some other brave soul to test.

I haven't tried anything else.

Great, this is good news!   Did you try the Power Sweep mode to see if they fixed it in your DSA815 with the new hardware?
