Would such thing exist in the market?
Been looking for an affordable one that could do 0-24 V for both DC and AC output at about 120 VA from 110-240 Vac input, not having much luck so far.
The DC component of the supply is easy, but cannot figure out the AC part?

Excellent find! 
Yes this meet the requirement.
I will try for a few more places, if I cannot find any then looks like this would be a buy.

Hi !   another possible solution ( I have used in the past ) is the  use of an Kepco operational
power supply like BOP-XXX   and excite the device with a function generator.
You can set DC ( +/-) voltages, and AC , coupled directly or across an AC trafo.

Hi

I have purchase CPS3205 from chines source available from Aliexpress, Ebay ,BengGood etc....
Cost is in the range of 50~60 USD include shipping (very low cost in compare to linear one)
this PSU provide 0-30V 0-5A switching power supply they work well but somewhat difficult to operate - have only one handle for current and voltage display is not very bright and they very lite weight (less then 1 KG) in compare to linear one I have, who weight above 10KG.
I can't be sure whether they fully isolated
