hpe5250a_biasChanList_Q
hpe5250a_biasChanList_Q
This function will query the instrument for the bias status 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 hpe5250a_biasChanList_Q(ViSession vi, ViInt16 bias_disen,
ViInt32 _VI_FAR biaschan_list[ ], ViInt32 _VI_FAR bias_status[ ] );
Parameters
vi
Instrument handle returned from hpe5250a_init( ).
bias_disen
Bias status for the query.
0 : confirms if the port is the bias enabled.
1 : confirms if the port is the bias disabled.
biaschan_list[ ]
Channel numbers to know the bias 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[ ]
Bias 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.
