The instrument automatically performs a system check, boots the Windows

ating system and then starts the vector network analyzer (VNA) application. If it
was terminated regularly, the VNA application restores all recall sets and instru-
ment settings of the previous analyzer session.

sets, to close the VNA application, to shut down Windows

sion.

Standby and ready state
Thestandby toggle key is located in the bottom-left corner of the front panel.
In standby state, the LED on the standby toggle key is orange, in ready state it is
green. The standby power only supplies the power switch circuits and the optional high
precision quartz (R&S
ZNA-B4, "Precision Oven Quartz Frequency Reference"). In this
state, it is safe to switch the AC power off and disconnect the instrument from the
power supply. In ready state, all modules are power-supplied. When switched to ready
state, the analyzer initiates its startup procedure.
