Power-off
When the instrument is in normal working status, it can only be powered off through operation of the
front panel power button.
Do not operate the power switch of the rear panel or disconnect the
power supply directly,
otherwise the analyzer cannot go into the power-off status, which may damage
the analyzer or cause the current status/measurement data being lost.
Please shut down the analyzer
properly.
If the operating system or application is abnormal and the
machine can’t be powered off
normally, press down
[Power On/Standby]
key for at least 4 s to turn off the analyzer.
2.1.3.3 Power off
In abnormal conditions, the analyzer shall be powered off to avoid causing personal injuries. At this
time, just disconnect the power cord (from the AC power outlet or rear panel power outlet of the
instrument). Therefore, a sufficient operating space should be reserved during instrument operation so
that the power supply can be disconnected directly when necessary.
2.1.4
Correct Use of Connectors
The connector will be often used in case of the tests of the network analyzer. Even though
connectors of the calibrators, test cables, and analyzers measurement ports are designed and
manufactured according to the highest standards, their service life is limited. As wear will be inevitable
during normal use and it will lead to reduction of the performance index of the connector and even make
it can’t satisfy the measurement requirements, the correct maintenance and measurement of the
connector can obtain accurate and repeatable measurement results, extend the service life of the
connector, and reduce the measurement cost. During actual use, please pay attention to the following
aspects:
2.1.4.1 Check of connectors
It is necessary to wear an anti-static wrist strap when checking the connectors. It is recommended
to use a magnifier to check:
1) the electroplated surface for wear and deep scratches;
2) the thread for deformation;
3) the thread and joint surface for metallic particles;
4) the inner conductor for bending and breakage;
5) the screw for improper rotation.
Check the connectors so as not to damage the instrument ports
Any damaged connector may damage the good connector connected to it even for the first time of
measuring connection, and to protect the ports of the network analyzer, the connector to be used shall
be checked before connection.
2.1.4.2 Connection
The connectors should be checked and cleaned before measurement and connection to ensure that
they are clean and undamaged. It is necessary to wear an anti-static wrist strap during connection. The
correct connection methods and procedures are as follows:
Step 1.
As shown in Fig. 2.4, align the axes of the two interconnecting devices to ensure that the
pins of the male connector has slipped concentrically into the socket of the female connector.
