Finally got an old 256MB usb stick digest by instrument.
Prepared disk with sector 3 etc.etc.
Wanna laugh?
Sending Factory mode command (without asking the response a NAG Screen appears on DSG telling:
"Command is protected"
Running the command without the key:
"USB disk not present"
A step forward but now..
 |O |O |O |O |O |O |O


OK got it.
the USB was recognized but size was 0.00
Reformatting it to FAT32 again, nag screen disappeared.  ^-^

So did you manage entering factory mode?

I wondered whether they changed the passphrase with the new FW version. But I just upgraded my DSG815 to 01.07 and the magic USB key still works.

Attached the Python scripts I use to enter and exit factory mode. You will have to edit the IP address.

Thanks for the great work all.

Update, my initial sweeps show good leveled output up though 2.35GHz, but seems to loose some calibration from there up to 3.6GHz.  I suspect they dont bother with full calibrations beyond the models specified freq range.

I get the E: drive and a small USB icon with the USB stick plugged in. I use a cheap Chinese uSD card adapter with an ancient uSD card, but it also should work with regular USB sticks.

I used Python with the vxi11 library for my experimentation. Looking at the code, I have just used the write(":PRIV:SOFT:MODE 0,FACTORYMODEENTRANCE") to set user mode, without expecting/reading a response. Then ask(":PRIV:SOFT:MODE?") to verify if it worked.

Dooh!  :(

Its not that the entire unit needs calibration, its just the OCXO will need to be calibrated once its in the unit, otherwise it will be very stably off frequency.

Hmm, I guess the 6.5V observed on the VCC pin will then be adjusted by the DSG to tune the OCXO.

From the datasheet of the OCXO used on the option for the DSG3000:
https://www.dptel.com/Products/ProductLevel4/2899

(highlighted 5 is the option based on part-number O22B-G445)

Not sure how to interpret that table. +/- 2.5V from nominal 5V supply voltage?
