how to send square dc signal to keysight 6642A dc power supply via GPIB USB-HS interface

[jaiswalm4]

I am using labview as function generator to provide dc signal to keysight 6642A(agilent technology product) using GPIB USB-HS(IEEE 488.2). I have been succeeded in generating signal in labview using simulate signal function but i don' know how to transfer signal to keysight 6642A. I have tried with GPIB write and VISA write but it dosen't work. Please help.
