age1439_input_offset

Sets the dc offset DAC setting for the current range. This description also includes the query:

	age1439_input_offset_get
	VXIplug&play Syntax
	#include "age1439".h
	ViStatus age1439_input_offset(ViSession id, ViInt16 coarseDac, ViInt16 fineDac);
	ViStatus age1439_input_offset_get(ViSession id, ViPInt16 coarseDacPtr, ViPInt16
	fineDacPtr);
	Description
	These values are normally set by age1439_input_autozero so you generally would use this
	command only for special situations. The resultant values can be saved to non-volatile RAM with
	age1439_input_offset_save.
	Each ac coupling range has a unique DAC setting. All dc coupling ranges use the same DAC
	setting as the highest range setting for ac coupling. The scaling between the coarse and fine DACs
	is approximately 100 to 1.
	AGE1439_OFFS_DAC_MIN sets the minimum dc offset DAC setting.
	AGE1439_OFFS_DAC_MAX sets the maximum dc offset DAC setting.
	Parameters
id	is the VXI instrument session pointer returned by the age1439_init function.
coarseDac	sets values of 0 to 255.
fineDac	sets values of 0 to 255.
coarseDacPtr	returns a pointer to the current value of coarseDac
fineDacPtr	returns a pointer to the current value of fineDac
	Return Value
	AGE1439_SUCCESS indicates that a function was successful.
	Values other than AGE1439_SUCCESS indicate an error condition or other important status
	condition. To determine the error message, pass the return value to “age1439_error_message” on
	page 102.
