Front Panel Connectors
The test ports and three USB connectors are located on the front panel of the
R&S
ZNA.
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
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
"Reflection S-Parameter Measurement"
●
With more than one test port, it is possible to perform full two-port, 3-port, ... , or n-
port measurements; see
Maximum input levels
The maximum input levels at all test ports according to the front panel labeling or the
data sheet must not be exceeded.
In addition, the maximum input voltages of the other input connectors at the rear panel
must not be exceeded.
Use a torque wrench when screwing RF cables on the test port connectors.
Direct Generator and Receiver Access
Hardware options R&S
ZNA<frequency>-B16 "Direct Generator/Receiver Access",
provide 3 pairs of SMA connectors for each test port, where <frequency> corresponds
to the network analyzer type. For detailed ordering information, refer to the product
brochure.
See also the section on Converter Control.
These connectors give direct access to the RF input and output signal paths.
●
The Source Out signal comes from the internal RF signal source. The Source In
signal goes to the test port. A power amplifier can be inserted between Source Out
and Source In to boost the test port power.
●
The Ref Out signal comes from the coupler and provides the reference signal. The
Ref In signal goes to the receiver input for the reference signal.
●
The Meas Out signal comes from the coupler and provides the received signal (to
be measured). The Meas In signal goes to the receiver input for the measured sig-
nal.
