Error in Using Multiple Unrelated Frequencies in One Simulation

Art254
Hello, In short, I have two frequency sources in my simulation deck and they are not related to each other. And in pss simulation, error encountered is: ERROR (CMI-2207): I179.V2: The fundamental frequency 'fund' 77GHz does not divide evenly into the stimulus frequency 'period' 200kHz. To fix the problem, adjust the fundamental frequency so that an integer multiple of 'fund' equals 'period'. The 77GHz is used for my RF block and the 200kHz is the frequency for a chopper amp. The chopper amp has period=1/fclk and my fclk=200kHz. What should I do to make spectre not think that the two freqs are related? Thanks a lot! Art p.s. btw, do you know how to type a message here so that when it is shown eventually my sentences are not all connected together as one big paragraph?
