You don't say how old the SA was before it was given to you.
Siglent probably expect you to buy a TG license.
The SSA3021X was delivered 10 days ago (and ordered 2 weeks ago with marked "FREE TG LICENSE").
If seller did not already give "authorized" code you need contact this Siglent seller/distributor where did you buy it!
If still not, then contact Siglent for get it.
After then you get TG Licence
here, this is automatic system for get licence codes for options. Only now is suprice that seller did not deliver this authorization code to you. This is seller error!:
For automatic licence key generation using authorization code and SSA serial number:
http://service.siglenteu.com/easyweb/If this all fails you sure get license code also from Siglent. You need your serial number and copy from purchase receipt. Are you sure seller did not include authorization code for get license, example printed in receipt or package list etc.
There in activation side you can also get instructions sheet (pdf) and there you find contacts: I think it is best you use Headquarter contact emal.
Just write subject: SSA3000X missing TG option license code
And then tell your serial number and tell that you did not get license for TG as Siglent offer is.
So there is hope that it go to right people for hadle it.
