RF Network Analyzers
System Operation
The 8719ET/ES, 8720ET/ES, and 8722ET/ES microwave network analyzers integrate a
synthesized source, signal separation devices, a three or four channel receiver for
measurement of test device characteristics, and a large-screen display. Figure 12-1 is a
simplified block diagram of the network analyzer system.

The built-in synthesized source of the analyzer generates a swept or continuous wave (CW)
signal in the following ranges:
The source output power is leveled by an internal ALC (automatic leveling control) circuit.
The output maximum power levels at the front panel are listed in Table 12-1 on page 12-4.
A portion of the source signal is routed to the R sampler receiver, and fed back to the
source for phase lock.
