I guess now it's time to save an image of the FRAM contents. --- End quote --- Hi Thomas: What Boot version do you have in your DSA815? And how (procedure used) did you downgrade your Firmware? You are very fortunate, and I'm happy for you. I'm asking about your Boot version because if you have 00.01.02 or 00.01.03 then you should be able to downgrade to FW 00.01.07 and use the Riglol Keygen to install the Options. And then reinstall FW 00.01.17. Jedit X Keygen Mac Adobe. Here's a video review, and here's a written review. Rigol's DSA 8.

And here's a written review. This is not possible if you have Boot version 00.01.04. And I thought that the newer DSA815's had Boot version 00.01.04 and could not downgrade the Firmware at all. But if you have Boot version 00.01.04 it must be that you just can't downgrade to a version that uses the older Boot version, but still able to downgrade a couple of versions. Anyway if you need FW 00.01.07 I can help you. Cheers, Ted TurboTom: Ted - I've got bootloader version 00.01.04 and hardware 00.08. I downgraded the same way as I did the update -- in the storage menu with an USB stick containing only the firmware file. I experimented with this before and found it to work. Apparently Rigol hasn't blocked the 'reverse route' like they did in the DS1000Z series. Yet if I remember correctly, I cannot downgrade to firmware versions that came with the previous bootloader version (I guess that's basically why the machines with the 01.04 bootloader cannot be unlocked with the 'Riglol' keygen). So nothing won but also nothing lost;). It will only get frustrating if Rigol should add some real innovations in follow-up firmware versions in future (I doubt they will.:P ). But who knows, maybe someone will find a different way to 'free' the later DSAs without write-protecting the FRAM. Cheers, Thomas TurboTom: Thanks Ted, I think I've got the files you were referring to somewhere as well. As yet I'm a little reluctant to apply that patch yet, especially since I've also got the Siglent SSA3021X(+);) which makes the Rigol look rather limited. Probably I'm going to (try to) sell the rigol eventually, yet sometimes it's also quite beneficial to have two such units, especially when analyzing some 'peculiarities' of one of the SAs. Donald snow cases in international relations pdf notes. What I'm actully missing more than the (test) licenses on the rigol, is the 10Hz RBW. And that's the one feature I cannot get on my instrument, whatever kind of tweak I appy to the FRAM. This Siglent (with a little 'help.' ) goes down to 1Hz RBW, quite a difference to the Rigol in its current configuration. Cheers, Thomas ted572: Re. DSA815 Firmware upgrade 00.01.17.00.04: See post (Reply) #785. I have made edits to this with explanations of the issue with newer DSA815's with Boot loader 00.01.04 and a potential fix by EEVbloger Howardlong (with some info in Reply #790). Thanks to TurboTom we have been alerted to this, and he covers it very well. Thanks Thomas. TurboTom: I intend to 'poke around' in my DSA815 a little to experiment with the FRAM and once open, I couldn't resist to peek into the RF section as well (didn't open that so far) - guess I was surprised to find something considerably different from the design shown in Dave's teardown video and the associated photos. Actually, the RF input section and the 1st mixer had been modified excessively and some other sections as well. As far as I can tell, the VCOs were kept practically unchanged. But now there are many 'permanent adjustment points', as it seems mostly for impedance matching, all throughout the areas where frequencies >500MHz are processed. Input protection also seems to have been 'beefed up' a little. One very funny detail is that apparently some of the 1st LO signal is coupled to the 1st mixer output through a low pass filter. Maybe there's some feed-through in the mixer that's compensated that way??
