5.1.2 TEST PROCEDURE
EIRP emission test method as below
1. The EUT shall operate on receive mode. And Interface cables, loads, and devices should
be connected to at least one of each type of the interface ports of the EUT and, where
practical, each cable shall be terminated in a device typical for its actual use. EUT shall
be placed at the 1.5m support on the turntable.

be placed at the 1.5m support on the turntable.
2. The test antenna at a horizontal distance of 3 m .It shall be raised and lowered from 1m
to 4m until a maximum signal level is detected by the measuring receiver. Then the
turntable should be rotated through 360° in the horizontal plane, until the maximum
signal level is detected by the measuring receiver. in both the vertical and the horizontal
polarization. Record the reading level, antenna position, polarization and turntable
position.

signal level is detected by the measuring receiver. in both the vertical and the horizontal
polarization. Record the reading level, antenna position, polarization and turntable
position.
3. Remove the EUT and replace it with a substitution antenna (the antenna should be
half-wavelength for each frequency involved). The center of the substitution antenna
should be approximately at the same location as the center of the transmitter. For
frequencies of 80 MHz and above, the dipoles should have their arm lengths set for
resonance at the frequency of test. Below 80 MHz, shortened arm lengths are
recommended. For measurements above 1 000 MHz, a waveguide horn is
recommended. The centre of this antenna should coincide with either the phase centre or
volume centre.

volume centre.
4. Feed the substitution antenna at the EUT end with a signal generator connected to the
antenna by a cable. With the antennas at both ends vertically polarized, and with the
signal generator tuned to a particular test frequency, raise and lower the test antenna to
obtain a maximum reading at the spectrum analyzer. Adjust the level of the signal
generator output until the previously recorded maximum reading for this set of
conditions is obtained. This should be done carefully repeating the adjustment of the test
antenna and generator output.

EIRP(dBm) = Pg(dBm) – cable loss (dB) + antenna gain (dBd)
where:
Pg is the generator output power into the substitution antenna.
Pre-test the 3 modulation to find 8DPSK is worse case, so only record 8DPSK test data.
