You might ask the maker what limitation requires you to stop moving the antenna. It may be that, while fast enough to read a wide range of frequencies quickly, once, it cannot make NEW scans fast enough to catch each height as it occurs. It might miss as much as a SA would, but where a SA misses some frequencies while scanning heights, the DMM would miss complete ranges. At least, that is the thought that comes to mind. You might slow down the speed with which antenna height is changed to combatthe problem, too.
This does not make it useless for tests where antenna height may be kept constant; I note the online information has it CISPR compliant. QUOTE The unit offers full compliance with the latest edition of CISPR 16-1-1 standard, including RMS-AVG detector and APD function. All CISPR and MIL-STD-461E RBW filters are available..
