The Low profi le pylon rotators are used for overall
small size and light weight DUT measurement.
The rotator’s drive and position feedback components
(i.e. synchro and encoder) are installed inside the tip
structure and only the “small” head protrudes from the
top.
The DUT is secured to the top of the rotator.
