Controlling the Test Set and Making Measurements
Calibrating the Test System
Measuring Transmission
Refer to Figure 2-4. With the 8753D/E set to measure forward
transmission (S ), the analyzer's RF source is being output through
21
the analyzer's PORT 1, and PORT 2 is set to receive the RF signal.
By using the following commands, you will connect PORT 3 of the test
set to the REFLECTION port, and you will connect PORT 8 of the test
set to the TRANSMISSION port. You will thus be measuring forward
transmission through the device under test when measuring S . This
21
will provide you with gain or insertion loss information.

Measuring Reflection
By leaving the DUT connected as in Figure 2-4 and setting the network
analyzer to measure S , you can measure reflection or return loss.
