HP 89410A for servo loop analysis?
(1/1)
aeg:
Hi all,

First time poster here looking for information on the HP 89410A vector signal analyzer. Would this instrument be suitable for analyzing servo loops? My interest is in generating Bode and Nyquist plots. (I understand I may have to do my own post processing of amplitude & phase information to get the Nyquist plot.) It looks like the 89410A covers both the 100Hz to 1+MHz range you could use a low frequency capable VNA for, and the 1Hz-1kHz range you would normally need a DSA for. It includes a signal generator, although this seems to be de-emphasized in the documentation. But it's not clear to me whether this is an intended application for the 89410A or if I would be fighting with the instrument. Would I be better off with something that says "network" instead of "signal" on the faceplate?
