For example SDG1000X:

Before
--------
<?xml version="1.0" encoding="UTF-8"?>
<nsp_system_info_root>
  <device>
    <system_information>
      <serial_number>
        <chip>SDG1YOURSERIAL</chip>
      </serial_number>
    <license><bandwidth_update_license>YOURLICENSEKEY11</bandwidth_update_license></license></system_information>
  </device>
</nsp_system_info_root>


After
------
<?xml version="1.0" encoding="UTF-8"?>
<nsp_system_info_root>
  <device>
    <system_information>
      <serial_number>
        <chip>SDG1YOURSERIAL</chip>
      </serial_number>
    </system_information>
  </device>
</nsp_system_info_root>

For SDG2042X should not be different.

I followed some method on here back in May/June that still worked. I like this thing, and the buttons make sense, easy to use

Hello,

I've attempted to enable my new SDG2042X to 120MHz and encountering some issues. First off I'm not a computer/sofware/network guru, so highly likely I've missed something simple. I've followed john95 routine and encountered some problems listed below.

I'm use a MAC running MAC OS High Sierra 10.13.6, and downloaded telnet as part of Home-brew without any issues.

4) SDG2042X: hook Ethernet cable, turn on SDG2042X, utility->interface->LAN Setup->DHCP on (Could not get DHCP to turn ON), write down IP address, for example: 192.168.1.20 (Used manual Configure in MAC for IP address and Subnet Mask from SDG2042X, no place for Gateway). (Now MAC indicates Ethernet Connected, but if I use DHCP on MAC Ethernet is not connected)
5) SDG2042X: Insert USB Stick into front panel USB socket, put SDG2042X to utility->/System/Firmware Upgrade->USB0->find file: telnet_SDG2000X.ADS->Recall, updating starts and fails after a while. Yes, it fails. So your version is never changed. (Yes this is what happens)
6) SDG2042X: LEAVE POWER ON SDG
7) computer console: access to SDG2042X file. type: telnet <SDG IP address> <SPACE> 10101 <RETURN>, for example: telnet 192.168.1.20 10101 (Get "telnet: Unable to connect to remote host" message, I tried loading SDG2042X IP and Subset Mask from DCHP enabled on MAC and Ethernet doesn't connect and get same telnet message).

Any help is greatly appreciated.

Best,

Mike

Since you're not a guru, and also using a Mac, you should be using a router/switch to connect your PC with the SDG. Doing it directly is prone to misconfigs.  To test connectivity use 'ping' command. If you don't have IP connectivity, no need to advance to telnet...

Also, the telnet .ADS should hang. It's a feature.

I plugged the ethernet cable from the SDG2042X into the WiFi router and was able to change the DHCP to "On" in the setup. A few minutes later the SDG2042X IP, Subnet and Gateway all changed and I was able to telnet into the SDG2042X as described by john95 procedure.

After carefully following the guidelines by john95 I was able to edit the file and save it. Did have to deviate some from this procedure and use "Esc, then :w, then return" to get the file saved. Then ":q! then return" to exit editor vi.

Unplugged USB and shut power down then repowered SDG2042X and sure enough have 120MHz capability now :)

Hopefully this will help anyone with a MAC.

Thanks for the help :-+

Next is enabling the SSA3021X Plus :)

Best,

Mike

On the telnet console, I get:

/ # cp /usr/bin/siglent/firmdata0/NSP_system_info.xml /usr/bin/siglent/firmdata0/NSP_system_info.x
ml.orig     
cp: cannot create '/usr/bin/siglent/firmdata0/NSP_system_info.xml.orig': Read-only file system


Any thoughts on why I don't have write access?

Thanks!

Did you enter the mount command properly and did it succeed?

Code: [Select]
mount -o remount,rw ubi2_0 /usr/bin/siglent/firmdata0

Wow, you're my hero!

The first time I did it, I got the busybox dialog; but I assumed that it properly mounted, since I was able to navigate to that location via 'cd'.

Thanks again!
