4.2.2 Allowed Variation Range of Supply Power Parameters
The spectrum analyzer is compatible with 100V~240V, 50Hz-60Hz
AC power, Table 4-1 lists the power requirement to run the
spectrum analyzer.
Table 4-1 Working Power Variation Range
Power Supply Parameter
Compatible Range
Voltage
100 - 240 VAC
Frequency
50 - 60 Hz ±10％
Power
28 W
To prevent or lower the risk of damage to the spectrum analyzer
from power interference between instruments, especially from
peak pulses produced by large power consumption instruments, a
220V/110V AC regulated power supply is recommended.
4.2.3 Power Cord Selection
The analyzer is equipped with a three-wire power cord in
accordance with international safety standards. This cable grounds
the analyzer cabinet when connected to an appropriate power line
outlet. The cable must be rated greater than 250Vac and 2A.

WARNING
Improper grounding may cause damage to the instrument,
or result in personal injury. Make sure the grounding
conductor of the spectrum analyzer is grounded before
turning on the instrument.
Always use a well-grounded power source. Do not use an
external power cable, power cord or an auto transformer
without grounded protection. If this product is to be powered
via an external auto transformer for voltage reduction,
ensure that its common terminal is connected to a neutral
(earthed pole) of the power supply.
