Hi ytass
Probably, your labview program continues after a timout or a bad interpretation on done command.
I am using an HP8566B and for long sweeps ( 5 s and up), after the TS command, I poll the analyzer every 1 s, and check the status word. In mine, bit 12 is true if operation has been completed. Now, is time to read traces, display and continue.
Hope it helps.
