| Rigol DG2052 making a screenshot and possible firmware hack |

Hello, i messed up my old Rigol DG1022 function generator by trying to update the device. Anyway, today arrived a brand new Rigol DG2052 function generator. I like the possibility to make screenshots an a device. Thats working great on the DG2052 in default function generator mode with a touch button in the lower right corner. But when switching to "(Frequency) Counter" mode , the "Print" touch button to take screenshots disapears. There is no option to take screenshots in frequency counter mode. When pressing the "Home" button with active "Counter" button, the display switches from "Counter" mode to default mode and the frequency is shown in a single line on the bottom and one can make a screenshot in this default mode using the "Print" touch button. I updated to the latest firmware 00.02.06.00.01. Still the same. The DG2052 has a LXI interface. I never used this before on any device. I found out, that i can capture screenshots from my laptop remote using the LXI interface and this command: echo ":DISPLAY:DATA? ON,OFF,PNG" | nc -w1 192.168.10.54 5555 | dd bs=1 skip=11 of=image.png With this command, i can capture a screenshot in "Counter" mode. But after taking the screenshot, the display on the device switches from "Counter" mode to default Mode and the display is locked. I have to manually unlock it using the hardware button. 1. Is there a trick to do a screenshot using one ore more hardware buttons (like on my Keithley DMM6500, i have to press Home+Enter to take a screenshot) in "Counter" mode? 2. Is there a SCPI command i can add to prevent the screen lock when using LXI/SCPI? 3. Can i unlock the device to full DG2102 mode (like on my DS1054Z or other DG series)? I attached some screenshots i took with the SCPI command. |

I added some pictures from inside the DG2052. Looks solid to me. |

Compare this to the DG800 / 900 PCB -- Different but still the same... Jim -- may I ask you to identify U603, the QFN24 next to the PLL? It's got to be some DAC but since on mine it's lasered blank, I haven't been able to figure out what it is exactly (audio codec??). Yours appears to have all the inscriptions still intact, so this shouldn't be too difficut. In your photos, I cannot identify the inscription. It's just something to satisfy my curiosity... ;) Btw, great photos and thanks for posting them -- this proves what we already suspected. |

Has anyone here tried a full memory dump via jtag from DG800/900/2000 series?? Do i only need the bdsl file for Spartan 6? |
