Settling time

b. The time until the measured value settles to within ± 0.6 % of the final result value after the out-

put voltage is changed from the initial value (0 V). Minimum rise/fall time of 70 ns is recom-

mended for minimizing overshoot.

1. Measurement conditions: The DUT is a resistive load chosen to adjust the flowing current to the

specified current in the table above. The capacitance of the cable between the RSU and the DUT

is 20 pF. Voltage is applied to the DUT by a channel of WGFMU/RSU in Fast IV mode and in

the 10 mA range, and current measurement is performed by another channel at 0 V in Fast IV

mode.
