Scan Advanced Polarity

Short name: Scan Advanced Polarity

This attribute sets the driving level for the Scan Advanced Output signal sent from the switch module through either the external (PXI) or front connector (SCXI) lines.

When the Scan Advanced Output signal is sent to one of the TTL lines, the driven level is always low and this property is ignored. Between each Scan Advanced Output signal, the line is not driven and is in a high-impedance state.

NISWITCH_VAL_RISING_EDGE	The line is driven up when the Scan Advanced Output signal is sent.
NISWITCH_VAL_FALLING_EDGE	The line is driven down when the Scan Advanced Output signal is sent.
