PERFORMANCE
The Model 6620A provides precisiophase measuremes with a
ypical accuracy of 0.02° and aesolutioof 0.01° over mosof
he frequencyange. Iwill accepa wideange of inpusignal
levels from 10mVrmso 320Vms and inpuwaveforms
including sine,riangle, square and pulses. A 5 digiLED display
provides cotinuous directeadouof phase angles betwee0.00°
and 360.00° or ±180°. Thesewoanges cabe manually o
automatically selected.
UNIQUE DESIGN
Two commofactorshawill affecthe accuracy of a phasemete
are distortioand/or broadbandoise presenoeither or both of
he inpusignals. A unique circuidesigused ithe 6620A
significalyeduces any effectshamay be caused byhesewo
factors.
Another problem found imosphasemeters ishe inabilityo
espondo very small phase angles,esulting ifluctuations o
incosistencies ithe metereading (sometimesefeedo as
ambiguity). To overcomehis problem,he 6620A uses a desig
haeliminates any ambiguitieshamay occur ateadingsear 0°,
180° and 360°, and allows measuremes as small as 0.01°o be
made
