Recommended separation distances between portable and mobile RF communications
equipment and the Auto Vector Fluid Immersion Simulator
The AutoVector Fluid Immersion Simulator is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the AutoVector Fluid Immersion Simulator can
help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the AutoVector Fluid Immersion Simulator as recommended below,
according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in
metres (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 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reection from structures, objects, and people.
