did you check the level accuracy of your DG4000 after the "liberation"? I found mine to be spot on up to 200MHz (DS4102 from Q4/2015). Maybe yours also doesn't need to be calibrated at all.

No. I haven't done anything more than view the output with my Scope.
IIRC; mine had some signal attenuation above the 60MHz limit; but, I haven't done anything specific to verify. Again; quick check using aglent scope.

If you haven't got a spectrum analyzer or a calibrated level meter, you may DIY a detector type level tester with a 50R terminator resistor (preferably 2*100R 1% 805 in parallel), a small signal, low capacitance schottky diode, a 10n smoothing capacitor and maybe a 10k load resistor, coupled to a multimeter. All this has to be assembled just a the back of a BNC connector to keep the impedance low. This "bodge" should give you a good idea of your generator's level accuracy.

I do have a Spectrum Analyzer (CMU200); but was a fleabay purchase so it's calibration isn't assured. The document I have:
"CalibrationProcedure.pdf"
doesn't appear to discuss calibration or measurement by Spectrum Analyzer.
Do you have a link to this "bodge" schematic and/or wiki?
EV:
I read this license.gen to my DG4162. It looks to work as earlier but the signal is about 1.4 dBm low at 200 MHz. Between 1 - 160 MHz signal is ok.
Is it possible to correct this by calibration?

Hi All,
I would like to update my Bootloader & Firmware, Attached is my current system
information for my DG4062.
I managed to find the necessary files to update it as the
current version is 00.01.07 and it says online that I need minimum
00.01.08 to run the current file but I can't find the instructions to Flash the bootloader or Firmware.
I'm not interested in Hacking my machine I just want to up date it to the latest version.
Could someone please send through some instruction on how to Flash the bootloader and Firmware.
I have also attached an image of my current system information.
Kind Regards
Stuart
