HART analog data frequency limits

My client plans on implementing HART at 1.2Khz on a line that measures quickly changing analog input values. If the analog values can also change hundreds and maybe thousands of times per second, what approach is taken to limit interference and let the digital and analog signals coexist? What are the fastest analog measurment speeds you have seen work?
