Upcoming Rigol DSG815/830

<< < (10/18) > >>

Its interesting to know that there might be mileage in enhancing the DSG815  :clap:

Despite it being released back in 2015 - its still a decent bit of Kit - especially when compared to the more recent Siglent offering of their SSG3000X range.

There is another thread - specifically for the review of the SSG3021X - but during the 'testing' - it had been constantly compared to the DSG815 - so for those following this thread - please hop over to here (last post as of today)

https://www.eevblog.com/forum/testgear/siglent-ssg3021x-testing-feedback-and-comments/msg3161586/#msg3161586

and review the findings on the DSG815 - quite a few tests have been made - the latest is a full FM stereo & RDS modulation on 108MHz (via EXT Modulation Input) - to test, tune or align any FM / RDS capable FM radio.

It has 4 Options (last 2 of them require additional HW).

PUM
PUG
IQ
OCXO

The licenses to enable them are similar to what rigup creates. The FW contains default ECC public and XXTEA keys but allows the use of specific ones.

If anyone can make a memdump, we can have a dry run.   :popcorn:

What's the procedure for a memdump? I may give it a try.

From my understanding - easiest way is to use a Jtag cable - to your PC and access the console
Dave's teardown video clearly shows the Jtag connector - its on the CPU board.

I think once the memdump is available then we can investigate  :popcorn:

Here's how to enter FACTORY and MANAGER/REPAIR modes:

Prepare a USB stick:
1. Format as FAT32
3. Write the following string to disc sector 3 of the USB stick (I used HxD):
35O8O228OLO8LNMN9690217963MN2O9ON46O9P05975K0047

Plug USB stick into the RF generator

Now the following SCPI commands will work:
:PRIV:SOFT:MODE 0,FACTORYMODEENTRANCE
:PRIV:SOFT:MODE 0,REPAIRMODEENTRANCE
:PRIV:SOFT:MODE 0,MANAGERMODEENTRANCE

The first parameter (0) seems to be ignored.
MANAGER and REPAIR seem to be identical, but entering REPAIR doesn't require the USB stick.

The current mode can be verified with:
:PRIV:SOFT:MODE?

To return to USER mode, power cycle the device or use
:PRIV:SOFT:MODE 0,USERMODEENTRANCE
or
:PRIV:SOFT:MODE 0,EXITCURRENTMODE

Additional menus show up when in FACTORY/REPAIR/MANAGER mode:
Syst > Service
Syst > Service > Calibration
Syst > Service > RF DataSyn
Syst > License > Delete

I haven't dared to mess with settings in factory mode yet (like changing the model to DSG830). Don't blame me if you break your RF generator  :-BROKE

And a little mystery: When triggering the check of the disk sector, an empty file with the name "LqepdclquJ.txt" is created on the USB stick.
