RE102 Purpose

Radiated emissions, electric field.

This requirement is applicable for radiated emissions from equipment and subsystem enclosures, and all interconnecting cables. For equipment with permanently mounted antennas this requirement does not apply at the transmitter fundamental frequencies and the necessary occupied bandwidth of the signal.

This test procedure is used to verify that electric field emissions from the EUT and its associated cabling do not exceed specified requirements.

RE102 Limits

Electric field emissions shall not be radiated in excess of those shown on Figures RE102-1 through RE102-4. Above 30 MHz, the limits shall be met for both horizontally and vertically polarized fields.

Test Equipment

The test equipment shall be as follows:

a. Measurement receivers.

b. Data recording device.

c. Antennas:

(1) 10 kHz to 30 MHz, 104 cm rod with impedance matching network. The signal output connector shall be bonded to the antenna matching network case.

(a) When the impedance matching network includes a preamplifier (active rod), observe the overload precautions in 4.3.7.3.

(b) Use a square counterpoise measuring at least 60 cm on a side.

(2) 30 MHz to 200 MHz, Biconical, 137 cm tip to tip.

(3) 200 MHz to 1 GHz, Double ridge horn, 69.0 by 94.5 cm opening.

(4) 1 GHz to 18 GHz, Double ridge horn, 24.2 by 13.6 cm opening.

d. Signal generators.

e. Stub radiator.

f. Capacitor, 10 pF.

g. LISNs
