When trying to update my DG4026 FW, nothing happens - as per follows:
a. I use an old 16M USB stick (FAT formatted)
[ and when sticking it inside while instrument is normally running, the message "“USB
Device Recognized” does appear ]
b. The appropriate "DG4000Update.GEL" file is in its root.
c. I strictly follow the Rigol DG40xx FW update instructions, as follows:
- Press the power on button on the front panel of the instrument - Checked !
- All of the buttons on the front panel will flash once. Immediately following the first flash of all of the buttons, press the Help button once - Checked !
- The Mod and Utility buttons will light.= Checked !
- Insert the USB drive with the new firmware upgrade into the USB port
on the front panel of the instrument. ( this must older 4GB or smaller) - Checked !
- The Utility button will flash and turn solid - Checked !
- The Store button will then flash and turn solid - Checked !
- The individual buttons in the Waveform Menu of the front panel will
flash and then go solid one-at-a-time. (except one) - Nothing happens
- After all of the buttons in the Waveform Menu turn solid,
all of the front panel buttons will flash and the instrument will reboot.
This should take approximately 5 minutes to complete - Nothing, even after 30 minutes wait...
Note - No damage either, FW version remains unchanged.
Does anybody have a clue of what's happening, or on how to overcome this ?
TIA
