Compensation Short Connection
Use to enable or disable short connection compensation. Refer to PMU connection compensation (on
page 5-30) for detail on setting up and using connection compensation.
Load Line Effect Compensation
Use to enable or disable load-line effect compensation (LLEC). Refer to Load-line effect
compensation (LLEC) for the PMU (on page 5-34) for detail on setting up and using load-line effect
compensation.
DUT Resistance (R DUT)
The DUT resistance value. Refer to DUT resistance determines pulse voltage across DUT (on page
5-61) for detail on calculating DUT resistance.
Max Voltage Estimator
The Maximum Voltage Estimator is a tool that enables you to calculate the maximum voltage and
current based on the selected voltage range and the DUT resistance value you type in. The estimator
does not affect the pulse output.
For a more accurate maximum voltage estimate, add the interconnect resistance to the DUT
resistance value. The typical resistance of a white SMA cable is 0.75 Ω and the typical prober pin-to-
pad resistance is 1 Ω to 3 Ω. Poor pin-to-pad contacts could be in the range of 10 Ω to 15 Ω.
The V Max and I Max values are valid with LLEC enabled or disabled. It is the maximum output of the
PMU. The LLEC does not change the maximum output voltage or current of the PMU.
Threshold Current
The current threshold allows you to set a threshold. If the threshold is reached or exceeded, the
present sweep is stopped. Testing continues with any subsequent sweeps.
This threshold is a comparison of the measurement after the pulse has been applied to the DUT (the
threshold value will be exceeded, at least slightly). The degree to which the signal exceeds the
threshold before the threshold is triggered is a function of the DUT response and test configuration.
Generally, smaller voltage step sizes will reduce the amount that the signal exceeds the threshold.
You can specify more than one threshold for each channel.
