The standby toggle switch is located in the bottom left corner of the front panel.
The key serves two main purposes:
●
Toggle between standby and ready state; see Chapter 3.8, "Standby and ready
state", on page 18.
●
Shut down the instrument; see Chapter 3.7, "Switching the instrument on and off",
on page 17.
4.1.4 Front panel connectors
The test ports and three USB connectors are located on the front panel of the
R&S ZNA.
4.1.4.1 Test ports
Numbered connectors:
●
3.5 mm male for R&S ZNA26
●
2.92 mm (K) or 2.4 mm male for R&S ZNA43
●
2.4 mm male for R&S ZNA50
●
1.85 mm male for R&S ZNA67
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 6.2,
"Reflection S-parameter measurement", on page 69.
●
With more than one test port, it is possible to perform full two-port, 3-port, ... , or n-
port measurements; see Chapter 6.1, "Transmission S-parameter measurement",
on page 62.
●
Use a torque wrench when screwing RF cables on the test port connectors.
●
See also Chapter 3.5, "Considerations for test setup", on page 15.
Connector usage
Two LEDs above each test port indicate the connector usage:
●
Tx on: connector is used as a source port
●
Rx on: connector is used as a receive port
●
both LEDs on: connector is used as a bidirectional (source and receive) port
