1.4.1 RF Input
The RF input is located on the top of the R&S FSH.
Connect a cable or DUT to the RF input with an N connector. Use a cable to connect
the DUT to the R&S FSH, if necessary.
Make sure not to overload the R&S FSH when a DUT is connected.
The maximum power that is permissible at the RF input is 20 dBm (or 100 mW).
The R&S FSH may be loaded with up to 30 dBm (or 1 W) for up to three minutes. If
you apply 1 W for a longer period, the R&S FSH may be destroyed.
The RF input is protected from static discharges and voltage pulses by a limiting
circuit.
Risk of electrical shock
In order to avoid electrical shock, the DC input voltage must never exceed the value
specified on the housing.
Risk of instrument damage
To avoid damage to the coupling capacitor, input attenuator or the mixer, the DC input
voltage must never exceed the value specified in the data sheet.
