Instrument damage caused by cleaning agents
Cleaning agents contain substances such as solvents (thinners, acetone, etc.), acids,
bases, or other substances. Solvents can damage the front panel labeling, plastic
parts, or screens, for example.
Never use cleaning agents to clean the outside of the instrument. Use a soft, dry, lint-
free dust cloth instead.
3.2.1 Test Ports
Numbered test port connectors:
●
Type N female connectors for the R&S ZNBT8. Depending on the equipped port
options there are 4, 8, 12, 16, 20 or 24 test ports.
●
3.5 mm male connectors for the R&S ZNBT20. Depending on the equipped port
options there are 8, 12, 16, 20 or 24 test ports.
The test ports serve as outputs for the RF stimulus signal and as inputs for the mea-
sured RF signals from the DUT (response signals). With a single test port, it is possible
to generate a stimulus signal and measure the response signal in reflection. For a
measurement example, refer to Chapter 5.2, "Reflection S-Parameter Measurement",
on page 71. With more than one test port, it is possible to perform full two-port, 3-
port, ... , or n-port measurements; see Chapter 5.1, "Transmission S-Parameter Mea-
surement", on page 64.
