5-3 Test Equipment Required For Test
Test equipment required to test the amplifier is listed in Table 5-2. Equivalent test equipment may
be substituted for any item, keeping in mind that a thermistor type power meter is required.
Note
All RF test equipment required must be calibrated to 0.05 dB resolutions. Any
deviation from the nominal attenuation must be accounted for and factored into all
output readings.
