A network analyzer supplies a sweep signal to a DUT, measures its
transmission and reflection, and displays the results as ratios against the
input signal from the signal source. The E5071C network analyzer consists
of the circuit modules shown in the following figure.

Synthesized Source
The synthesized source generates an RF sweep signal in the specified
frequency range.
The signal source is phase-locked to a highly reliable quartz crystal
oscillator to maintain a high level of accuracy in its frequency as well as to
achieve precise phase measurements. The level of RF output power is
controlled within the range of -15 to +10 dBm by the internal ALC
(automatic leveling control) circuit.
