agb220xa_biasPort
This function will select which input port is the bias port on the specified card. For
each card, you can specify the same or different bias port.
Syntax ViStatus _VI_FUNC agb220xa_biasPort(ViSession vi, ViInt16 bport_cardno,
ViInt16 bias_port);
Parameters vi Instrument handle returned from agb220xa_init( ).
bport_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.
bias_port Input port number to be set to the bias port. 1 to 14 (input port 1
to input port 14).
If the bias input port and a couple port have been assigned to the same input port, the
bias mode and the couple mode cannot be used in parallel.
agb220xa_biasState
This function controls the bias mode for the specified card. When bias mode is ON,
the input bias port is connected to all bias enabled output ports that are not
connected to any other input ports. Bias disabled output ports are never connected to
the input bias port when bias mode is ON.
The bias mode cannot be set to ON when the ground mode is ON.
Syntax ViStatus _VI_FUNC agb220xa_biasState(ViSession vi, ViInt16 bstate_cardno,
ViInt16 state);
Parameters vi Instrument handle returned from agb220xa_init( ).
bstate_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 Bias mode. 0 (OFF) or 1 (ON).
