ankle strap. Anti-static effect will be better when two measures are used at the same time. If used
independently, only the former can make sure the safety. In order to ensure the user safety, the ground
isolation resistance of anti-static components must be 1MΩ at least.
The follow anti-static measures should be taken to reduce static damage:
 All instruments must be properly grounded to prevent static electricity.
 The internal and external conductor of the cable should respectively contact with the ground temporarily
before the coaxial cable and instrument are connected.
 Workers must wear the anti-static wrist strap or take other anti-static measures before contact with the
connector or wire or any assembly.
Warning
Voltage range
The above anti-static measures are not suitable for the places with the voltage higher than 500V.
3.1.1.3 Power on/off
1) Precautions before powering-on
Check the following items before powering on the instrument.
a) Confirm the power supply parameters.
The 4051 Series Signal/Spectrum Analyzer is internally equipped with 220V AC power module (using 220V
AC power supply) or 110V/220V self-adaptive AC power module (option, using 110V or 220V AC power
supply working in self adaptive way, which means to automatically switch operating mode based on external
AC power supply voltage). Therefore, please carefully read power requirements on the rear panel before using
the instrument. Table 3.4 lists the requirements of the external power supply for normal operation of the Series
Signal Analyzer.

Prompt
Prevent mutual interference of various power supplies.
In order to prevent mutual interference of power supplies of various devices, especially the instrument
hardware damage caused by peak pulse interference of high-power equipment, it is recommended to use the
220 V or 110 VAC voltage-regulated power supply to power on the Series Signal Analyzer.
b) Confirm and connect the power line.
The 4051 Series Signal/Spectrum Analyzer adopts three-core power line interface and conforms to national
safety standards. Before the Series Signal Analyzer is energized, it should be ensured that the ground wire in
its power line is reliably grounded. Floating or improper grounding may result in damage to the instrument
and even operator injuries. Do not use the power line with no protective ground wire. When the appropriate
