ade explorer set instance value

hi,

i create one simulation in ade assembler, several  test for simulation, for example, i place one analoglib “port” in schematic, but different test need to set different port source type, like dc and sine, how could i to switch cross different test in ade explorer?

for PAC simulation, i need to check display small signal params and set PAC level( iknow ican set variable for this level), how can i to control check box? 

if checkbox is not cheched, and i set PAC level by variable, is this variable take effect?

thanks
