Function Details
Compliance
To Set Compliance
The following points must be noted when setting the compliance.
• If the current compliance value is too low, the SMU will take a long settling
time.
• The SMU will reach voltage compliance if the SMU cannot force the specified
current for the following reasons:
• Over current for test device.
• Another channel has reached compliance.
• Current measurement data of another channel has reached the limit for the
present measurement range.
• If you set the manual mode for compliance polarity of the DI command, set the
voltage compliance value as shown below. See Figure 6-6.
• If the output current is a positive value or zero (Iset ≥ 0):
Set the compliance value to more than Vref.
• If the output current is a negative value (Iset < 0):
Set the compliance value to less than Vref.
In Figure 6-6, ΔI is 2.5 % to 12 % of the range value in the current output range.
Figure 6-6 Allowable Voltage Compliance (DI, Manual Mode)
NOTE If you set the manual mode for compliance polarity of the DI command, and if you
do not set the allowable compliance value, the SMU may force Irev, not Iset. Refer
to “Operation of SMU in Current Output” on page 6-14.
