WARNING
To prevent electric shock, take all necessary safety precautions when
working on equipment where hazardous live voltages may be present.
WARNING
To avoid equipment damage and possible injury, do not operate
the instrument or an accessory outside its rated supply voltages or
environmental range.
CAUTION
Exceeding the overvoltage protection range on any connector can cause
permanent damage to the instrument and other connected equipment.
To prevent permanent damage, do not apply an input voltage to the trigger
or reference output of the VNA.
2.3 Grounding
WARNING
The instrument’s or SOLT-AUTO E-Cal module’s ground connection
through the USB cable is for functional purposes only. The instrument and
accessories do not have protective safety grounds.
To prevent injury or death, or permanent damage to the instrument, never
connect the ground of an input or output (chassis) to any electrical power
source. To prevent personal injury or death, use a voltmeter to check that
there is no significant AC or DC voltage between the instrument’s ground
and the point to which you intend to connect it.
CAUTION
To prevent signal degradation caused by poor grounding, always use the
high-quality USB cable supplied with the instrument.
2.4 External connections
WARNING
To prevent injury or death, use only the power adaptor supplied with the
instrument. This is approved for the voltage and plug configuration in your
country.
