hpe5250a_biasChanCard
hpe5250a_biasChanCard
This function will enable or disable bias on all the output ports of the specified card.
Syntax ViStatus _VI_FUNC hpe5250a_biasChanCard(ViSession vi,
ViInt16 disable_enable, ViInt16 bias_cardno);
Parameters vi Instrument handle returned from hpe5250a_init( ).
disable_enable Bias status. 0 (sets bias enabled card) or 1 (sets bias disabled
card).
bias_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.
hpe5250a_biasChanList
This function will enable or disable bias on all the output ports specified by the
biaschan_list.
The parameter ’biaschan_list’ is an array of integers with each integer representing
one channel. The last number of the ’biaschan_list’ should be “0”(numeric zero) to
identify the end of the list. The maximum number of channels that can be specified
by the list is 100.
Syntax ViStatus _VI_FUNC hpe5250a_biasChanList(ViSession vi,
ViInt16 biaschan_disen, ViInt32 _VI_FAR biaschan_list[ ]);
Parameters vi Instrument handle returned from hpe5250a_init( ).
biaschan_disen Bias status. 0 (sets bias enabled port) or 1 (sets bias disabled
port).
biaschan_list[ ] Channel numbers. 5 digits integer. ABCDE. where A: card
number, BC: input port number, DE: output port number.
Top zero(s) can be ignored. For example, if A=0, BC=01, and
DE=01, channel number should be 101 instead of 00101.
hpe5250a_biasChanList_Q
This function will query the instrument for the bias status for the channels given in
the list.
