Electrostatic protection (ESD)
Static electricity is highly destructive to electronic components and equipment, so this instrument must be powered
up on the anti-static table. Attention should be paid to electrostatic protection when using the device. If condition
permits, the following electrostatic protection measures may be taken:
a) Make sure all the instruments are correctly grounded to prevent static generation.
b) The staff must wear anti-static wrist straps before contact with connectors or core wires or any assembly.
c) The center conductor must be grounded before the cable is connected to the instrument in the test. This can be
realized through the following steps: Connect a short-circuiter to one end of the cable to realize short circuit
between the central conductor and outer conductor of the cable. When wearing a anti-static wrist band, hold
on to the casing of the cable connector and connect the casing to the other end of the cable before removing
the short-circuiter.

Input/output port protection
The standard impedance of the RF port of S3302 series spectrum analyzer is 50Ω. Therefore, the appropriate load
impedance for the test signal or port should be applied in strict accordance with the port requirements during
operation, so as to prevent subsequent circuits from damage.

Cleaning of display of front panel
If required after operation of certain time, the display panel of the instrument can be cleaned according to the
following steps.
a) Shut down the instrument and disconnect the power line.
b) Wipe display panel with clean and soft cotton cloth with detergent.
c) Dry display panel with clean and soft cotton cloth.
d) Do not connect power line until detergent dries out.
The RF input end of the spectrum analyzer has the requirements for maximum allowable input level. The applied signal must not exceed the limits; otherwise,
this instrument may be damaged.
