Table 6-7. Electromagnetic Immunity (continued)
The Model 8930 Radio Frequency Generator is intended for use in the electromagnetic
environment specified below. The customer or the user of the generator should ensure that it is
used in such an environment.
Immunity Test
Portable and mobile RF communications equipment should be used no closer to any part of the
Model 8930, including cables, than the recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Conducted RF
EN 61000-4-6
Radiated RF
EN 61000-4-3
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,
should be less than the compliance level in each frequency range.
Interference may occur in the vicinity of equipment marked with the following symbol:
Notes:
At 80 MHz and 800 MHz, the higher frequency range applies.
■
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 Model 8930 is used exceeds the
applicable RF compliance level above, the Model 8930 should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocating the device.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
