I don't have access to the RF service monitor I used for the sine wave. Today I hooked up my FPGA and looked at the output of a 2.5V digital signal and it looks like the rise time is averaging 3.3ns and Vamp was 1.99V. I'm now wondering if the service monitor I used was working correctly, I don't have another scope to compare.
The frequency shows correctly but I'd expect that even with 50MHz bandwidth. When testing BW the service monitor I started with a 1V p-p signal at 10MHz and increased the frequency until the voltage was at 0.7V p-p which happened at 65MHz. It could very well be a signal generator issue and not a problem with the scope.
Yep. My new DS1052E just arrived from China:serial: DS1ET1519nnnnnfirmware: 00.04.01 ( 00.04.01.00.02)dsp: 00.01fpga: 03.07hardware version: 58It would certainly be very much appreciated if Gizmo could cook up a modified 00.04.01.00.02 firmware!I had a hunt around for the stock firmware on the interwebs but couldn't see it anywhere.
Well, I tried and it doesn't work. Scope sees the USB stick, I can see the file in file manager, but when it's plugged in the scope ignores the file.Must be because the upgrade file is seen as a downgrade by the scope?
Have you check the md5 hash after transferring to pen drive?
Have you format your sd card in fat32?
Remember that you need to put the .rgl file in the main root of your sd card
Yep. That's where it is.Hmmm. The file shows .RGL in CAPS. Changed the extension to lower case, no change.File shows up in Rigol file manager as:F:\DS1000EUpdate.rglscope still ignores it. A shame there isn't a log file accessible that shows the scope accessing the file and deciding it's the wrong version to allow an upgrade.Rigol should bring out a Linux version of the DS1052E, I say!
Right I tried with an older USB stick that was FAT16. Rigol sees the drive, tells me it know it's FAT16, but doesn't upgrade.Bummer.Thanks for the suggestions. Stuck in 25MHz waiting for Gizmo to come to the rescue with a 00.04.01 update.
Just got my DS1052E (same serial and versions as Drewbie) and was hoping to upgrade but nothing happens when I insert the USB drive. Also tried the 2.02 file without any luck.

Yes, it's exactly the same as Drewbie's:Quoteserial: DS1ET1519nnnnnfirmware: 00.04.01.00.02dsp: 00.01fpga: 03.07hardware version: 58
25Mhz? DS1052E is 50Mhz Oscilloscope!

Can still be to use old downgrade method on 00.04.01.00.02 firmware ?thxQuote from: internetlab on July 25, 2013, 09:29:04 pmQuote from: apis on July 25, 2013, 08:44:40 pmYes, it's exactly the same as Drewbie's:Quoteserial: DS1ET1519nnnnnfirmware: 00.04.01.00.02dsp: 00.01fpga: 03.07hardware version: 58Maybe my firmware version was 00.04.01.00.01, it was for sure 00.04.01 and no problem for downgrade.The one solution is the rigol support
Set the max sample rate (or more aptly the usable bandwidth) to 100MHz.
May not actually have a flat response to 100MHz due to input stage filters.
The screen may flicker but can be fixed with factory settings reload.
I must never do a user mode auto recalibration (or at least do it 30mins after powerup but before reflash).
The model number doesn't change (unlike the original hack).
