The length of the delay (0 to 10 ks)

Details

This command sets a delay for the selected source function. This delay is in addition to normal

settling times.

After the programmed source is turned on, this delay allows the source level to settle before a

measurement is made.

If you set a specific source delay (smu.source.delay), source autodelay is turned off.

When source autodelay is turned on, the manual source delay setting is overwritten with the

autodelay setting.

When either a source delay or autodelay is set, the delay is applied to the first source output and then

only when the magnitude of the source changes.

Example

smu.source.func = smu.FUNC_DC_VOLTAGE

smu.source.delay = 3

Set the function to voltage. Set a 3 s delay

after the source is turned on before a

measurement is taken.
