Measurement Units and Functions
Compliance
Power Compliance
In addition to V compliance or I compliance, you can set power compliance for the
VAR1, VAR2, and VAR1' channels of sweep measurement. However, if the pulse
output function is used for VAR1 or VAR1' channels, you cannot set power
compliance for the VAR1 or VAR1' channel that is set to pulse output.
The power compliance setting range for each SMU is as follows:
HRSMU 1 to 2 W
MPSMU 1 to 2 W
HPSMU 1 to 20 W
If you specify I compliance and power compliance for a V sweep source, the
4155C/4156C changes the I compliance at every voltage step. The I compliance is
set to the smaller value of I compliance and Attempt value below. See Figure 7-10
(a).
Icomp = power compliance / step voltage
If you specify V compliance and power compliance for an I sweep source, the
4155C/4156C changes the V compliance at every current step. The V compliance is
set to the smaller value of V compliance and Vcomp value below. See Figure 7-10
(b).
Vcomp = power compliance / step current
