System Spec with the same models in parallel
N =Number of Slave + 1,
P=Power rating of Master,
I=Current rating of Master,
R=Resistance rating of Master,
S=Slew time of Master should be less than the slew time of Slave
Psystem=P x N
Isysetm=I x N
Rsysetm=R/N
Ssystem-min=S x N if Master slew-time=Slave slew-time
Accuracy and Offset = Master Specification x N
Slew Time = Master Specification x N
1) With the sa me models, this configura tion ca n be working a s one single unit with increa sed power a nd current ra ting.
2) To further improve current a ccura cy in Ma ster+Sla ve configura tion. Use r ca n perform current ca libra tion even in
Ma ster+Sla ve mode.
3) It still ha s a ll the step, tra nsient or pulse fea tures. Sla ve slew time must be set to ½ of Ma ster’s slew time.
4) The CC-Low, CC-Mid, CP-Low, CP-Mid, CR-Mid, CR-High\won't be used Ma ster-Sla ve configura tion.
5) It could have sta bility issue a t CV mode with very low current leve l; this a lso depends upon the wiring a nd DUT. It
would be better a dding equiva lent RC filter a t the input termina l for this ca se.
