agb220xa_biasChanList_Q

This function will query the instrument for the status, bias enabled or bias disabled, for the channels given in the 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.

The “bias_status” parameter is an array of integers containing the return values of the query. The “bias_status” array returned will correspond one to one with “biaschan_list” parameter.

Syntax	ViStatus _VI_FUNC agb220xa_biasChanList_Q(ViSession vi, ViInt16 bias_disen,
	ViInt32_VI_FAR biaschan_list[ ], ViInt32_VI_FAR bias_status[ ] );
Parameters	vi	Instrument handle returned from agb220xa_init( ).
	bias_disen	Query type.
		0 : checks if the port is the bias enabled.
		1 : checks if the port is the bias disabled.
	biaschan_list[ ]	Channel numbers to check the status. 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.
	bias_status[ ]	Status of the channels given in the biaschan_list. Returned

value depends on the setting of bias_disen as shown below: when bias_disen=0, 0 means bias disabled, 1 means enabled. when bias_disen=1, 0 means bias enabled, 1 means disabled.
