2.1.2 Power Supply
3656 Series Vector Network Analyzer uses 220V or 110V alternating currents. The requirements
of analyzer on external power supply are listed in the following table:
Table 2-1 Requirements of Power Supply
Power Supply Parameters Applicable Range
Output Voltage AC220V AC110V
Output Power >150W >150W
Operating Frequency 50Hz 50/60Hz
To prevent or reduce damage to hardware of Analyzer due to mutual disturbance generated by
different equipment through power supply, especially potential destruction of Analyzer hardware
caused by peak pulse disturbance generated by high-power equipment, 220V or 110V AC
stabilized voltage supply is preferred to supply power for Analyzer.
To prevent damage to instruments and personal injury:

Do not use power cord without protection;

Properly ground the protection cord of power supply socket. Do not float or keep improper
grounding.
2.1.3 ESD Protection
Pay attention to ESD protection when using instruments. The following ESD protection measures
shall be taken if possible:
1. Ground yourself before cleaning and checking test port of instrument or connecting. You may
realize it via grabbing metal case of grounded instrument or shell of test cable connector.
2. Ground central conductor of cable first before connecting cable to instrument and performing
testing: connect short circuit on one end of cable and make central conductor and external
conductor short-circuit. When wearing antistatic wrist strap, you shall grab the shell of cable
connector and connect the other end of cable and remove short-circuit.
