2.3.2.1
Networks with DHCP
The R&S
ZN-Z84 is preconfigured to use the dynamic host configuration protocol
(DHCP). In such networks, the R&S
ZN-Z84 is automatically assigned a free IP
address.
2.3.2.2
Static IP Configuration
With static IP configuration, the static IP configuration data are usually provided
by the network administrator. They can be activated on the R&S
ZN-Z84 using
remote control.
2.3.2.3
Point-to-Point Connections
Establishing a simple network – a LAN connection between an R&S
ZN-Z84 and
a computer without integration into a larger network – requires assignment of an
IP address for the R&S
ZN-Z84 and the computer. The 192.168.xxx.yyy IP
addresses are available for this. The values for xxx and yyy range from 1 to 254;
the subnet mask length is 24 or higher. The IP address for the gateway must also
be specified, but it is not of significance in this case.
2.3.3
Direct Control
The Direct Control interface allows to establish a direct connection between the
measurement bus of a VNA of the R&S
ZNx family and the FPGA controlling the
routes of a switch matrix R&S
ZN-Z8x. As Direct Control bypasses the matrice's
microcontroller it significantly reduces the switching times compared to manage-
ment via USB or LAN.
The R&S
ZNB/ZNBT must be equipped with the Device Control option
"B12".
The FPGA is put on the measurement bus by connecting the matrice's "Direct
Control IN" interface to the analyzer's "DIRECT CTRL" interface; cascading of
Direct Control connections is possible via "Direct Control OUT" (see
A suitable connection cable is provided with option R&S
ZN-B121 (order no.
1323.9290.00).
