AUX IO Port Commands

Sets the polarity of the user external input strobe signal. This external input strobe signal must be at least 200 ns wide, and user must hold assert 16 input data bits stable 20 ns before the active edge of the user input strobe and hold the data stable for at least 100 ns after the active edge of the user input strobe.

These SCPI commands are only valid for PXBs equipped with a 36-pin AUX IO connector.

POSitive	This choice configures a rising edge of the external strobe signal to latch the data.
NEGative	This choice configures a falling edge to latch the data.

Sets the AUX I/O port input strobe. In Dedicated operating mode, the instrument will always be in Free Run mode. If Multiplexed mode is selected, either Free Run or User input strobe mode can be selected.

These SCPI commands are only valid for PXBs equipped with a 36-pin AUX IO connector.

FREE	This choice configures the new input data as latched based on an internal clock.
USER	This choice configures the a user supplied strobe signal so, it is used to latch the data..

Configures the AUX IO port as either Multiplexed or Dedicated. These SCPI commands are only valid for PXBs equipped with a 36-pin AUX IO connector.

Equivalent GUI settings: System > Global AUX IO Settings.

MULTiplexed	This choice configures the AUX I/O port operating mode to Multiplexed for real-time applications.
DEDicated	This choice configures the AUX I/O port operating mode to Dedicated for real-time applications.

Sets the polarity of the AUX output sample clock. This signal indicates that the 16 input data bits have been latched and will be output in both Free Run and external input strobe mode. The output pulse will be at least 200 ns wide.

These SCPI commands are only valid for PXBs equipped with a 36-pin AUX IO connector.

POSitive	This choice configures a a pulse with a rising edge will be asserted to indicate when the 16 input data bits have been latched.
NEGative	This choice configures a a pulse with a falling edge will be asserted to indicate when the 16 input data bits have been latched.
