Output slew time
Figure 3-2 demonstrates the effect of output slew time on overall settling. Total time after
changing the source value before accurate measurements can be taken includes both the
slew time and the measure circuit settling time.
NOTE When not performing a sweep, the output slew time is not part of the auto source
delay. Therefore, for best accuracy when turning the output on or changing the
voltage source value, allow a delay of 3.07ms/V of output change before trigger-
ing a reading. This delay can be programmed by setting the trigger delay
[Section 10, “Trigger model (front panel operation)”]. Also, while the output is
slewing, the compliance status bit for the channel will be set (Section 14,
“Status Structure”). You can poll the compliance bit to determine when the pro-
grammed source value is reached and an accurate reading can be taken.

Manual delay
Manual delay for each channel can be set from 0000.00000 to 9999.99800 seconds. Man-
ually setting the delay disables auto delay.
