ORDERING INFORMATION
•
Build your confi guration using the ordering example below.
1
Model tower height is defi ned as the distance from
the base of the offset slide to the center of the roll axis.
The height of the model tower assembly will impact
pickup mode in lower positioners containing an
elevation axis. Defi ne elevation measurement angles
and verify lower positioner specifi cations when
confi guring this product.
2
The lower positioner may require electrical wiring
and/or an RF path to support the model tower.
Options are available for the lower positioner,
including EX002, SR, and RJ. Lower positioner
is purchased separately.
3
All accuracy data is based on no-load conditions.
Contact ORBIT/FR for accuracy under load conditions.
4
Roll axis is equipped with adjustable limit switches
capable of approx 20° up to 900° total travel. When
rotary joint options are specifi ed, limit switches remain
but are electrically disabled. Roll axis is factory-set at
400° (± 200°).
5
Rotary joint options may alter the original physical
profi le of the roll axis stage. Consult ORBIT/FR.
6
Verify model tower’s total swing radius (G - clearance
to absorber) when specifying this product for use
inside an anechoic chamber.
7
Dimensions may vary depending on fi nal confi guration.
8
Standard offset slide travel is 24 inches. Other lengths
are available in one foot increments, up to 8 feet.
9
For special requirements with space limitations,
the linear offset slide can be provided upside-down
in order to move the mast without moving the slide.
10
An optional alignment fi xture can be installed between
the roll axis positioner and mast, with or without a
base riser.
