We have used a math channel formula for phase difference calculation but how to initialize it using API function in C language or #C through visual studio??

Is it possible to initialize the math channel through commands or through API function? because i have not found any API function for the math channel? and shall we capture or store the math channel data into excel file through API commands because it is not mentioned in yours programming guide?

we have used a math channel for the phase difference measurement of two channel that is given into your forum i.e. ((((atan(1/tan(pi*(B/10000)))/pi)+(B/10000))*-((atan(1/tan(pi*(C/10000)))/pi)+(C/10000)))+0.25)/0.002777777 * (((atan(1/tan(pi*T))/pi)+T)*2) and we are using DC average from the measure...
