Caution Statements
The following equipment cautions appear in the text and are repeated here for
emphasis.
See page 9.
See page 9 and 113.
See page 18.
See page 18, 20 and 55.
See page 18 and 21.
CAUTION
Airflow is essential for proper unit operation. Do not obstruct the unit or soft
case exhaust ports!
CAUTION
+20 dBm (100 mW) max. RF input for the Spectrum Analyzer and +22 dBm
(160 mW) max. RF input for the Vector Network Analyzer.
Exceeding the maximum input will damage the SignalHawk. If unsure of power
levels, measure the test connection with a power sensor before using the
SignalHawk.
CAUTION
Vector Network Analyzer has a +22 dBm (160 mW) max. RF input. Exceeding
the maximum input will damage the SignalHawk. If unsure of power levels,
measure the test connection with a power sensor before using the
SignalHawk.
CAUTION
Do not turn on a DC bias if the thru cable is attached from the VNA In to the VNA
Out. This will damage the VNA input and destroy the unit.
CAUTION
Center conductor cabling should be discharged prior to connecting. See
“Discharging Static Electricity” on page 131 Any large electrostatic discharge or
high power RF applied directly to the RF input or output will cause internal
damage and void the warranty.
Power to any adjacent broadcast antennas should be shut down as well. If
adjacent antenna broadcasts cannot be terminated, then adding sufficient
external attenuation to the input of the instrument prior to connecting is
recommended. Failure to do so could result in irreparable damage to the
SignalHawk.
