Hello Ted, can you tell us what exactly you did to improve the RL of the bridge in post 871 ?
tnx N8AUM
Applicable models and component versions:
------ Embedded software version number: 00.01.09 and later
------ BOOT version number: 00.01.04 and later
------ Digital FPGA version number: 00.05 and later
------ RF FPGA version number: 00.05 and later
------ Main board version number: 00.05 and later

I recently got a used DSA815-TG and would like to update the firmware on it. I have some questions, maybe someone here can help me out.
The unit seems to be quite old and has the following versions:
Main Board: 00.04
RF Board: 00.05
Digital Board: 00.04
Firmware: 00.01.08
Boot: 00.01.02
Now i downloaded the V00.01.18 update from the Rigol site, but in the installation instructions in the archive say:QuoteApplicable models and component versions:

Does that mean, that i can't update my unit with this update? Are there other updates available for older units? The problem with the current firmware is, that the remote-commands seem to be not fully implemented, so the automation software i would like to use does not work.
Another question - The device has options enabled (keygen) - Will these options be lost, should the update be possible?
thanks,
Sebastian
I was looking at that but way out of my price range. I just purchased the SIGLENT SSA 3032X, already found a bug LOL
Hi,
Got a strange problem with the DSA815 and would like to see if anyone else is observing it.
Bought it recently about 6 months ago.
When using the DSA815-TG to get a spectrum output from a HF transmitter, seen a strange spurious signal in the area of 14.3 MHz.
Specifically, when a signal is fed to the instrument, in the area around 14.3 MHz eg 14.25 MHz or 14.35 MHz, appart from the original signal there is also displayed another signal (mixing product?), for that see attached images 501/2/3/5/6/7. When feeding the instrument with a signal at exactly 14.3 MHz, then the observed phase noise gets beyond the instrument's advertized limits, for that see the attached image 504.png
To verify the problem, I replaced the HF transmitter with a lab signal generator, the DG1022Z.
Seen the exact problem again.
The screenshots attached are from that setup, DG1022Z transmitting into DSA815-TG and the problem is still there so it was not the HF transmitter.
Has anyone else seen this or is it just my unit?.
Version of Main Board:00.09
Version of Radio Frequency Board FPGA:00.05
Version of Digital Board FPGA:00.05
Version of Firmware:00.01.18
Version of Boot:00.01.04
And btw, how can I submit a ticket to Rigol?
Thanks,
Christos
Don't worry, mine is doing exactly the same ....
It is about 3 years old and the MB version is 00.04
Probably an issue with all DSA815 systems.
Yes, a am aware that the unit can save to a thumb drive, I even put a button to do that on the first form.
Thanks for the discouragement in the pursuit of knowledge and the sharing with others.
I followed the link you provided, I am not good at German, and Google failed to translate. Maybe I'll try again later.
There is now a new RSA5000 Series of High Performance Real Time Spectrum Analyzers shown on the Rigol Web Site.
DSA815, DSA832, DSA875 Adding FRAM Write Protect
This mod. is to permanently retain the factory supplied DSA800 Series Trial Options (fully functional) forever. Suggestion - do it at least several hours before they expire.
Note: When they are gone, they will be gone forever, with currently no other way to get them.
