Figure 5-2 Diagram for testing of max. output power, max. input power and output power flatness
c) Testing steps for max. output power, max. input power and output power flatness:
Max. output power test: connect the instrument as shown in Figure 5-2, set the working frequency
1
range of the signal source to 32GHz - 40GHz with the stepping by 0.5GHz, set the output power of the
signal source connected to the input port of the amplifier to 0dBm or any other value that can make the
amplifier in the working state of saturated output, record the reading on the power meter at each test
frequency point, and calculate the sum of the max. output power degree and the attenuation value on the
attenuator, which is just the max. output power.
Max. input power test: observe the working state of the amplifier at the max. input power. It is
2
required that the amplifier should be able to work normally without damage at each test frequency point
and return to the original working state when it is lower than the max. input power.
Output power flatness test: place the internal amplitude stabilization key on the rear panel of the
3
instrument to the "Internal Amplitude Stabilization" working state, test and record the output power of the
1dB compression point at each test frequency point, and calculate the average value of the max. and min.
output powers. Neither the max. nor the min. output power should exceed the flatness requirement,
namely, it should be in the range of 3dB above the average value and 3dB below the average value.
