The amplifier is installed in a 19 inch rack which receives power from a +27 Vdc power source. Description of EUT exercising: During testing where a single carrier was used, the input level was adjusted to obtain 190 Watts out on a single channel. During testing where more than one channel is used, the power of each carrier must be reduced so the total power output is no greater than 190 Watts. CW, GSM and W-CDMA signal were used during the testing and are indicated in each section of this report as appropriate.
