a. When the input signal level is lower than –40 dBm, the analyzer’s preamp should be turned on and the
attenuator set to 0 dB.
b. Example, using 1 ppm as frequency reference accuracy of the analyzer, at frequency of 2.402 GHz,
frequency accuracy would be in the range of ±(2.402 GHz
× 1 ppm) Hz ± 100 Hz = ±2402 Hz ± 100 Hz
= ±2502 Hz.
c. tfa = transmitter frequency × frequency reference accuracy.
