Edit: It's a startup script so you should reboot.

Second update, this method did not work on firmware 1.28. Assuming "do the same procedure" means scroll and push select on the .dbg file the same way licenses are installed, selecting the .dbg file does nothing as far as I can tell: there are no UI notifications or changes and SSH does not get enabled, before or after rebooting the scope. Keeping the USB key in the scope during reboot also seems to have no effect.

I just wanted to share the results of my testing.

Model: GDS-1054B
FW: v1.28
Purchase date: October 2020

Search trigger - Works!
Segmented Acquire - Works!
100 MHz Bandwidth - DOES NOT WORK

After installing BW100, on the "System Information" page it says "Bandwidth upgraded to 100MHz by DS1KB-BW100", however when I measure the actual bandwidth, it didn't change before or after applying the license (I tested with a signal of ~10mV and again at ~1V). I then tried ti apply BW200 and BW300. It says that they are installed correctly, but once I restart, it still says 100 MHz in Sys Info.


nctnico:
That is correct. The bandwidth is limited to below 100MHz in the hardware. You are not the first to run into this.

I’ve tried this hack and it say error loading license check license version my version is 2.3 I’ve tried the 2.3 or newer Clearcode line starting with 0x19495CFF what am I doing wrong?

Hi,

Could you install the SA license ? I have the GDS-1054B with 1.28 firmware and installed all licenses with this clear code


--- Code: ---uint[] ClearCode = { 0x19495CFF, 0x257130A3, 0x3D1B58BA, 0x74B0DC51 };
--- End code ---

all licesnces were installed except the Spectrum Analyzer which gave me the license error.

is there any trick to that one?
