3-point linearity protocol
The following notes must be taken into account if option F3 ("3 point linearity protocol") has
been selected in feature 550 ("Calibration").
The 3 points of the linearity protocol are defined as follows:
R
A
500 (19.7)
6000 (236)
1
3
2
A0023272
36 Points of the 3-point linearity protocol; Dimensions: mm (in)
A Distance from reference point R to first measuring point
R Reference point of the measurement
1 First measuring point
2 Second measuring point (centrally between first and third measuring point)
3 Third measuring point
Measuring point Position
1
st
measuring point • At the distance A from the reference point
• A = antenne length + antenna extension (if present) + 500 mm (19.7 in)
• Minimum distance: A
min
= 1 000 mm (39.4 in)
2
nd
measuring point centrally between 1
st
and 3
rd
measuring point
3
rd
measuring point 6 000 mm (236 in) below the reference point, R
The position of the measuring points may vary by ±1 cm (±0.04 in).
The linearity is checked under reference conditions.
