4.9.2 Measure Delay and Settling Time
In the Pulse source mode and the Sweep source mode, the 6243/44 waits for the source value and DUT to
settle before measurement.
The following explain the 6243/44’s settling time and the required Measure Delay.
(1) Voltage source
The 6243/44’s settling time (Ts) is calculated from the voltage source change value (Vs) and source
limiter set value DIL (digits) according to the following formula. Set the Measure Delay (Td) higher
than Ts.

• When the current limiter range is 320 A to 2 A: Ts = 0.3 + (0.8 + 5000/DIL)  Vs/100 [ms]
• When the current limiter range is 32 A: Ts = 0.3 + (0.8 + 13000/DIL)  Vs/100 [ms]
