the generator for an output frequency of 881MHz
(1960MHz) for cellular (PCS) band operation. Set
the power level to -25dBm.

appears on the spectrum analyzer should have a
magnitude of about -11dBm in high-gain and FM
modes. In low-gain modes, the magnitude should
be about -27dBm. Be sure to account for cable
losses (between 0.5dB and 2dB) and circuit board
losses (approximately 0.5dB) when computing gain
and noise figure.
by using a network analyzer. This has the advan-
tage of displaying gain over a swept frequency
band, in addition to displaying input and output
return loss. Refer to the network analyzer manufac-
turer’s user manual for setup details.
