AIN#(0:13)_SETTLING_US
- Starting Address: 42000
Settling time for command-response and AIN-EF readings.
  • Data type: FLOAT32  (type index = 3)
  • Readable and writable
  • Default value: 0
  • T8:
    • Ignored. This register has no meaning on the T8.
  • T7:
    • 0 = Auto. Max is 50000 (microseconds).
    • Minimum firmware version: 0.9328
  • T4:
    • 0 = Auto. Max is 10000 (microseconds).

AIN_ALL_SETTLING_US
- Address: 43904
Settling time for command-response and AIN-EF readings. A write to this global parameter affects all AIN. A read will return the correct setting if all channels are set the same, but otherwise will return -9999. Max is 50,000 us.

STREAM_SETTLING_US
- Address: 4008
Time in microseconds to allow signals to settle after switching the mux. Does not apply to the 1st channel in the scan list, as that settling is controlled by scan rate (the time from the last channel until the start of the next scan). Default=0. When set to less than 1, automatic settling will be used. The automatic settling behavior varies by device.
  • Data type: FLOAT32  (type index = 3)
  • Readable and writable
  • Default value: 0
  • T8:
    • Ignored. The T8's analog input chain does not rely on settling time.
  • T7:
    • The T7 will select the settling time based on resolution and gain settings. When the sample rate is above 60 kHz, settling time will be set to ~5 us. Max is 4400.
  • T4:
    • The T4 will default to 10 us. When the scan rate is above 20 kHz, settling time will be set to 5 us.
