Digital filtering, enabled by default, prevents the switch module from being triggered by pulses that are less than 150 ns on PXI trigger lines 0–7. Some devices used with a switch may only be able to send triggers that are less than 150 ns. For the switch module to recognize these pulse widths, digital filtering must be disabled.
|Caution When digital filtering is disabled, it is possible for the switch module to be triggered by noise on the PXI trigger lines. If the device triggering the switch is capable of sending pulses greater than 150 ns, you should not disable digital filtering.|
