8000A FFT Download

I have had no luck downloading FFT Function Traces to a PC. I have rarely had success however most of the time the trace is truncated at some point followed by what appears as sine wave data, guessing the scope is overwriting. One case is a simple CW, the other is a swept tone using the MAX function to trace the sweep. Signal is 60-80 MHZ, below is setup for sweep. The sweep takes about 2 minutes to cover the range and the MAX display is perfect. CVI Code then selects the source, reads preamble and downloads the waveform, BYTE mode, 500K of which 5K is in band. Assuming memory depth is time domain only. Any help appreciated, at wits end, IF Testing on a Digital Station....
