Theory of Operation
Theory of Operation
The following is a description of the operation of the U3025AE10. Reference the
U3025AE10 block diagrams shown in
Figure 37 on page
40. This section assumes the user
has a general understanding of couplers, switches, and network analyzers.
RF Switch Components
All RF switches are mechanical. The switches select the RF paths from the PNA Source
and Receiver through interconnect cables to Test Set port paths 3 through 12.
Source to Odd Ports (1-11)
The Port 1 Source Output from the PNA is routed into a matrix of switches in the Test Set.
This matrix routes the Source to one of the 6 odd ports and terminates the other odd ports.
Source to Even Ports (2-12)
The Port 2 Source Output from the PNA is routed into a matrix of switches in the Test Set.
This matrix routes the Source to one of the 6 even ports and terminates the other even
ports.
Receiver to Odd Ports (1-11)
The Port 1 Receiver Input from the PNA is routed into a matrix of switches in the Test Set.
This matrix routes one of the signals from the 6 odd ports to the PNA "A Receiver" and
terminates the other odd ports.
Receiver to Even Ports (2-12)
The Port 2 Receiver Input from the PNA is routed into a matrix of switches in the Test Set.
This matrix routes one of the signals from the 6 even ports to the PNA "B Receiver" and
terminates the other even ports.
RF Coupler Components
Test Set ports (3 - 12) provide the signal separation of the source and receiver paths. The
Test Set ports can either stimulate or receive a signal to the DUT.
