Driver Function Reference
hpe5250a_biasState
bias_port Input port number to be set to the bias port. 1 to 10 (input port 1
to input port 10).
hpe5250a_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.
Syntax
ViStatus _VI_FUNC hpe5250a_biasState(ViSession vi, ViInt16 biasstate_cardno,
ViInt16 state);
Parameters
vi Instrument handle returned from hpe5250a_init( ).
biasstate_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
automatic configuration mode). For the configuration mode, see
hpe5250a_func.
state Bias mode. 0 (off) or 1 (on).
hpe5250a_close
This function terminates the software connection to the instrument and deallocates
system resources. It is generally a good programming habit to close the instrument
handle when the program is done using the instrument.
Syntax
ViStatus _VI_FUNC hpe5250a_close(ViSession vi);
Parameters
vi Instrument handle returned from hpe5250a_init( ).
hpe5250a_closeCard_Q
This function will query the card for the channels closed of the specified card.
The parameter ’closechan_list’ contains the channel numbers returned by the
instrument. This will be an array of integers terminated by ’zero’ to identify the end
of the list. Array of enough length should be passed to the function.
Syntax
ViStatus _VI_FUNC hpe5250a_closeCard_Q(ViSession vi, ViInt16 close_card,
ViInt32 _VI_FAR closechan_list[ ]);
