Specification test limits are given in Table Table Peak output power limits Assigned frequency Maximum antenna Peak output power* Equivalent field strength range, MHz gain, dbi W dbm 3m, db( V/m)** *- The limit is provided in terms of conducted RF power at the antenna connector. If transmitting antennas of directional gain greater than 6 dbi are used, the peak output power limit shall be reduced below the stated value as follows: by 1 db for every 3 db that the directional gain of antenna exceeds 6 dbi for fixed point-to-point transmitters operate in MHz band; without any corresponding reduction for fixed point-to-point transmitters operate in MHz band; by the amount in db that the directional gain of antenna exceeds 6 dbi for the rest of transmitters. **- Equivalent field strength limit was calculated from the peak output power as follows: E=sqrt(30 P G)/r, where P is peak output power in Watts, r is antenna to EUT distance in meters and G is transmitter antenna gain in dbi Test procedure The EUT was set up as shown in Figure 7.2.1, energized and its proper operation was checked The EUT was adjusted to produce maximum available to end user RF output power The resolution bandwidth of spectrum analyzer was set wider than 6 db bandwidth of the EUT and the field strength of the EUT carrier frequency was measured with antenna connected to spectrum analyzer/ EMI receiver. To find maximum radiation the turntable was rotated and the measuring antenna height was swept in both vertical and horizontal polarizations The maximum field strength of the EUT carrier frequency was measured as provided in Table and associated plots The maximum peak output power was calculated from the field strength of carrier as follows: P = (E d) 2 / (30 G), where P is the peak output power in W, E is the field strength in V/m, d is the test distance and G is the transmitter numeric antenna gain over an isotropic radiator.
