Precautions in Use
1.
Before starting the measurement
When turning on the power, don't connect DUT.
Before starting the measurement, check to see the output power level.
After the power has been turned off, wait at least 30 seconds before turning it back on again.
2.
Removing of case
Do not open the case to one except service man of our company.
3.
When abnormality occurs
If smoke or any unusual smells or sounds come from the analyzer, turn off the power to the PC, remove
the power cable, and contact Advantest.
4.
Electromagnetic interference
Electromagnetic interference may be caused to the television or the radio.
The analyzer or PC may be the cause of electromagnetic interference if the electromagnetic interference
is reduced when the power is turned off.
Reduce electromagnetic interference using the following methods
•
Change the direction of antenna of the television or the radio.
•
Place a PC with the R3755x/R3760 installed away from any electrical devices such as TVs or
radios.
•
Use a separate power supply to the power supply with electrical devices such as TVs or radios
attached.
5.
Prevention of Electrostatic Buildup
To prevent damages to semiconductor parts from electrostatic discharge (ESD), the precautions shown be-
low should be taken. We recommend that two or more measures be combined to provide adequate protec-
tion from ESD. (Static electricity can easily be built up when a person moves or an insulator is rubbed.)
