In the Transmit tab of the Setup form there is an AM carrier level setting.
I haven't tried it yet, but I suspect it will allow you to do DSB with
minimal carrier.

Hi Joe.
Welcome to the club. No questions are dumb except for the ones about
having the software generate more sunspots :-)
As far as your first question, the FLEX-5000 PA has the ability be
variably biased for class A operation. The software controls to do that
have not been added to PowerSDR to do it. I have no idea where that
enhancement is on the "to do" list. I know the engineering team has been
VERY busy with the FLEX-3000 and the other new products that will be
coming out later this year.
As for question #2, I do not believe you can do what you are asking with
the current software. I have not seen any control for reducing the
carrier in AM, but the software gurus will have to answer that one.

Hi gang. First I'm a newbie to the Flex 5000 so be gentle for my dumb
questions.
I checked the KB and it came back with nothing on my two questions.
1. I see the 5000 PA can operate class A. How does one do this? Is it
controlled with the PowerSDR or is this a hardware mod?
2. Can one insert a low level carrier when operating DSB with PowerSDR?
Sort of like AM with a greatly reduced carrier.
