4.1.4.2 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.
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.

The direct generator/receiver access can be used to insert external components (exter-
nal signal separating devices, power amplifiers, extension units etc.) into the signal
path. This feature enables custom measurements, e.g. to test high-power devices or to
extend the dynamic range.
If no external components are connected, each Out/In loop must be closed using a
jumper.
See also Chapter 3.5, "Considerations for test setup", on page 15.
4.1.4.3 USB connectors
The front panel offers three USB connectors of type A (master USB).
The USB ports can be used to connect external devices, e.g.:
●
external PC accessories such as mouse or other pointing devices, a keyboard,
printer or external storage device (USB stick, CD-ROM drive etc.)
●
external measurement equipment such as calibration units, power meters, fre-
quency converters, extension units, signal generators, or switch matrices
