RECOMMENDED SEPARATION DISTANCES
Table 13. Recommended Separation Distances between Portable and Mobile RF Communications
Equipment and the BladderScan BVI 3000 System
The BladderScan BVI 3000 system is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the BladderScan BVI 3000 system can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the BladderScan BVI 3000 system as recommended below,
according to the maximum output power of the communications equipment.
RATED MAXIMUM OUTPUT
POWER OF TRANSMITTER
(W)
SEPARATION DISTANCE ACCORDING TO FREQUENCY OF TRANSMITTER (m)
150 kHz to 80 MHz
d=1.2 √P
80 MHz to 800 MHz
d=1.2 √P
800 MHz to 2.5 GHz
d=2.3 √P
0.01 0.12 0.12 0.23
0.1 0.38 0.38 0.73
1 1.2 1.2 2.3
10 3.8 3.8 7.3
100 12 12 23
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in
meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
Note: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reection from structures, objects and people.
ACCESSORY CONFORMANCE TO STANDARDS
To maintain electromagnetic interference (EMI) within certied limits, the system must be used with the cables,
components, and accessories specied or supplied by Verathon
®
. For additional information, see the System
Components & Accessories and Component Specications sections. The use of accessories or cables other
than those specied or supplied may result in increased emissions or decreased immunity of the system.
