Issue Details

I'm seeing a very high rise time (5 microseconds) in my USB-6211 even though the slew rate indicates to me that it should be able to rise 5 volts over 1 microsecond. Why is it taking so long to rise?

Solution

The settling time for the USB-6211 over a full-scale step is 32 microseconds, so 5 microseconds to settle at a new value is within expected behavior for this device.
