Repeatability

To verify the overall repeatability of the measurement, the test was repeated
20 times, using the same DUT. For each test cycle, the Power Reference Level
Test and the Power Reference Level Adjust tests, were carried out; at no point
during these tests was the 1mW on the DUT adjusted. The thermistor was
disconnected and reconnected between each test with the sensor position
rotated each time. The results for this evaluation are shown in
