agb220xa_groundPort
This function will select which input port is the ground port on the specified card.
For each card, you can specify the same or different ground port.
Syntax ViStatus _VI_FUNC agb220xa_groundPort(ViSession vi, ViInt16 gport_cardno,
ViInt16 gnd_port);
Parameters vi Instrument handle returned from agb220xa_init( ).
gport_cardno Card number. 1 (card 1), 2 (card 2), 3 (card 3), 4 (card 4), or 5
(all card) in the normal configuration mode, or 0 (all card in the
auto configuration mode). For the configuration mode, see
agb220xa_func.
gnd_port Input port number to be set to the ground port. 1 to 14 (input
port 1 to input port 14).
The input ground port and a ground enabled input port cannot be assigned to the
same input port.
If the ground input port and a couple port have been assigned to the same input port,
the ground mode and the couple mode cannot be used in parallel.
agb220xa_groundState
This function controls the ground mode for the specified card. When ground mode is
ON, the input ground port is connected to all ground enabled input ports and output
ports that are not connected to any other input ports. Ground disabled output ports
are never connected to the input ground port when ground mode is ON.
The ground mode cannot be set to ON when the bias mode is ON.
Syntax ViStatus _VI_FUNC agb220xa_groundState(ViSession vi, ViInt16 gstate_cardno,
ViInt16 state);
Parameters vi Instrument handle returned from agb220xa_init( ).
gstate_cardno Card number. 1 (card 1), 2 (card 2), 3 (card 3), 4 (card 4), or 5
(all card) in the normal configuration mode, or 0 (all card in the
auto configuration mode). For the configuration mode, see
agb220xa_func.
state Ground mode. 0 (OFF) or 1 (ON).
