Details
This option is only used when digitize signal coupling is set to AC.
When the signal coupling is set to AC, there may still be some DC signal content that comes in with
the AC signal. To allow this signal to settle out, you can set AC coupling filter to slow. When the filter
is set to slow, the instrument adds an 800 ms delay before making measurements.
When the AC coupling filter is set to fast, the instrument adds an 80 ms delay before making
measurements. Set the AC filter to fast for faster settling when measuring rapidly changing inputs.
For most digitize voltage measurements, the 80 ms delay is enough time for the range to settle.
