| ViReal64 | R/W | None |
Specifies a time duration, in seconds, for which the signal must be quiet before the device arms the trigger. The signal is quiet when it is below the trigger level if the trigger slope, specified by the NIRFSA_ATTR_IQ_POWER_EDGE_REF_TRIGGER_SLOPE attribute, is set to NIRFSA_VAL_RISING_SLOPE or when it is above the trigger level if the trigger slope is set to NIRFSA_VAL_FALLING_SLOPE.
By default, this value is set to 0, which means the device does not wait for a quiet time before arming the trigger. This attribute is useful to trigger the acquisition on signals containing repeated bursts, but for which each burst may have large changes in signal power within itself. By configuring the minimum quiet time to the time between bursts, you can ensure that the trigger occurs at the beginning of a burst rather than at the signal power change within a burst.
Default Value: 0

Specifies whether the digitizer OSP block delays Reference Triggers, along with the data samples, moving through the OSP block or if the Reference Triggers bypass the OSP block and are processed immediately.
Enabling this attribute requires the following equipment configurations:
- All digitizers being used must be the same model and hardware revision.
- All digitizers must use the same firmware.
- All digitizers must be configured with the same I/Q rate.
- All devices must use the same signal path.
PXIe-5663/5663E—Read the value of the NIRFSA_ATTR_IF_FILTER attribute to determine the IF filters used by the PXIe-5663/5663E.
PXIe-5665/5667/5668—Refer to the device-specific information in the NIRFSA_ATTR_DEVICE_INSTANTANEOUS_BANDWIDTH attribute to determine the IF filters used by the PXIe-5665/5667/5668. If you set the NIRFSA_ATTR_FFT_WIDTH attribute, refer to the device-specific information for this attribute and the NIRFSA_ATTR_DEVICE_INSTANTANEOUS_BANDWIDTH attribute to determine the IF filters used. For frequencies less than 3.6 GHz, set the NIRFSA_ATTR_RF_PREAMP_ENABLED to the same value for all devices.
PXIe-5665 14 GHz—Set the NIRFSA_ATTR_PRESELECTOR_ENABLED to the same value for all devices.
If the I/Q rate is set programmatically for I/Q acquisitions, the following attributes should be identical for the best device synchronization:
