Putting into Operation
R&S FSH
1145.5973.12 1.4
E-14
Switching on the Spectrum Analyzer
The R&S FSH can be powered using either the included power supply unit or internal battery. When
fully charged, the built-in nickel metal hydride battery provides an operating time of about four hours. On
delivery, the battery in the R&S FSH may be flat. Therefore, it must be charged before the R&S FSH
can be used. If the instrument is switched off, the charging time is four hours.
When the adapter is used, the R&S FSH’s battery is charged simultaneously.
Insert the jack plug of the power supply unit into the POWER ADAPTER connector on the right-hand
side of the carrying handle so that it locks into position. Then connect the power supply unit to an AC
outlet. The voltage range of the power supply unit is 100 V to 240 V.
Caution!
Only the supplied power supply unit – the R&S FSH-Z33 – may be used to power the
R&S FSH or charge the battery from the AC supply.
Prior to use, make sure that the AC supply voltage is compatible with the voltage
specified on the power supply unit. Before inserting the power supply unit into the AC
power outlet, attach the appropriate adapter.
In vehicles, the battery can be charged from the cigarette lighter socket using the R&S FSH-Z21 cable.
Caution!
It is strictly forbidden to operate the R&S FSH via the cigarette lighter socket while the
vehicle is in motion or the engine is running. In these cases, the R&S FSH must be off.
While the battery of the R&S FSH is being charged via the R&S FSH-Z21 adapter with
the stock number 1145.5873.02, the adapter must not be connected to the vehicle’s
ground (for example, via the RF connector). This does not apply to the new
R&S FSH-Z21 adapter with the stock number 1300.7579.02.
To switch on the R&S FSH, press the yellow button
at the bottom left of the front panel.
To indicate that it is connected to the AC supply, the
R&S FSH displays a connector symbol in the middle of
the display above the softkey labels.
When the R&S FSH is switched on, it recalls the settings that it was using when it was last switched off.
Note:
If the internal battery is completely flat, the R&S FSH cannot be switched on even though it
is connected to the AC supply via the power supply unit. In this case, the internal battery
must be charged for a while with the instrument switched off. Only then can the instrument
be switched on.
