I try to write a program in Labview to control ADF4360-8 to output a 200MHz microwave signal. The ADF4360-8 is control by 3 24bit array latch through a parallel port to PC, how can I Write a program to send the 24bit arrray to the ADF4360-8. I have a sameple code, but I don't think i works perfect, since when I ask for 200MHz, it only gives me 191MHz.
