9. Technical Specification
Declaration – electromagnetic immunity – for ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING
Guidance and manufacturer's declaration – electromagnetic immunity
The MAT1260001 is intended for use in the electromagnetic environment specified below.
The customer or the user of the system should ensure that it is used in such an environment.
Immunity test
Conducted RF
IEC 61000- 4-6
Radiated RF
IEC 61000-4-3
NOTE 1
At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection
from structures, objects and people.
a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the
electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured
field strength in the location in which the Span system is used exceeds the applicable RF compliance level above, the system should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the system.
b. Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.

should be used no closer to any part of the CT515,
including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter
Recommended separation distance
d = 1.167√P
d = 1.167√P
d = 2.333√P
Where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
be less than the compliance level in each frequency
range.
