Measurement is made using a broadband power meter capable of making peak and average measurements while the EUT is operating at its maximum duty cycle (>98%), at maximum power, and at the appropriate frequencies. 5.1.3 Test Procedure Used KDB 558074 D01 DTS Meas Guidance v04 – Section 9.2.3 5.1.4 Test Settings The maximum average conducted output power may be measured using a broadband average RF power meter. The power meter shall have a video bandwidth that is greater than or equal to the DTS bandwidth and shall utilize a fast-responding diode detector. a) As an alternative to spectrum analyzer or EMI receiver measurements, measurements may be performed using a wideband RF power meter with a thermocouple detector or equivalent if all of the conditions listed below are satisfied. 1) The EUT is configured to transmit continuously, or to transmit with a constant duty factor. 2) At all times when the EUT is transmitting, it shall be transmitting at its maximum power control level. 3) The integration period of the power meter exceeds the repetition period of the transmitted signal by at least a factor of five. b) If the transmitter does not transmit continuously, measure the duty cycle (x) of the transmitter output signal as described in Section 6.0. c) Measure the average power of the transmitter. This measurement is an average over both the on and off periods of the transmitter. d) Adjust the measurement in dBm by adding 10log (1/x), where x is the duty cycle to the measurement result. 5.1.5 Test Setup The EUT and measurement equipment were set up as shown in the diagram below.

The S = PG / (4πR²) Where S = power density in mW/cm² P = transmit power in mW G = numeric gain of transmit antenna R = distance (cm) The calculations in the table below use the highest gain of antenna for client EUT. These calculations represent worst case in terms of the exposure levels.
