General Principles of Operation
System Description
System Description
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 E5070B/E5071B network analyzer consists of the circuit modules shown in Figure
E-1.

Synthesized Source
The synthesized source generates an RF sweep signal in the following frequency range.
E5070B: 300 kHz ~ 3 GHz
E5071B: 300 kHz ~ 8.5 GHz
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 dBm ~ +10 dBm by the
internal ALC (automatic leveling control) circuit. The E5070B/E5071B with option 214,
314, or 414 comes with a source-stepping attenuator which allows the user to set the power
level in the range of 50 dBm ~ +10 dBm.
