1145.5980.12 1.3 E-12
Setting up the Instrument
The Handheld Spectrum Analyzer R&S FSH has been designed for operation in labs as well as for on-
site use for service and maintenance applications.
For any application, the R&S FSH can be set up to optimize ease of operation and the viewing angle of
the display.
When used as a desktop instrument, the R&S FSH can
either be laid flat or it can be propped up using the
fold-out support at the back.
The R&S FSH can be laid flat for operation from
above. Because the grip is slightly raised at the back,
the R&S FSH is tilted forward to give the optimum
viewing angle for the display.
For use as a desktop, fold out the support at the rear
so that the instrument can easily be operated from the
front and the display can be read easily (see Fig.).
For on-site installation and service measurements, it is
best to hold the instrument with both hands. All the
controls are easy to reach (e.g. with your thumbs). Use
the R&S FSH-Z25 carrying bag so that you have both
hands free to adjust the DUT. The R&S FSH can be
placed in the hanger provided on the open bag for this
purpose.
To secure the instrument in place, affix its carrying handle to the front of the carrying bag with the
Velcro tape.
The carrying handle at the top of the R&S FSH can also be used to hang it from cabinet doors, for
example. The shape of the grip ensures that the instrument does not fall off.

Putting into Operation R&S FSH
1145.5980.12 1.4 E-12
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 isswitched off, the charging time isseven hours.
When the AC power supply 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 Car Adapter
R&S FSH-Z21.
Caution! Operation of the R&S FSH via the cigarette lighter socket while driving or while the
engine is on is prohibited. During this time, the R&S FSH must be off.
While the battery of the R&S FSH is being charged via the 12 V Car Adapter
R&S FSH-Z21 with the stock number 1145.5873.02, the car adapter must not be
connected to the vehicle's ground (for example, via the RF connector) under any
circumstances. 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.

1145.5980.12 1.5 E-12
Spectrum Analyzer Connectors
The R&S FSH has the following connectors:
RF input
Connect the RF input via a cable with an N connector to the DUT. Make sure that it is not overloaded.
The maximum permissible continuous power at the RF input is 20 dBm (100 mW). It can be loaded with
up to 30 dBm (1 W) for a maximum of three minutes. If the instrument is loaded with 1 W for longer, it
heats up to such an extent that it may be destroyed.
Caution! The RF input is AC-coupled. However, the DC input voltage must never exceed the value
specified on the housing; otherwise the coupling capacitor at the input may be destroyed
and, thus, the input attenuator or mixer as well. The RF input is protected from static
discharges and voltage pulses by a combination of limiting circuits and high-voltage
arresters.
Input for external trigger or external reference (EXT TRIG/EXT REF)
Via the EXT TRIG/EXT REF BNC connector, either an external trigger signal is applied to start a
measurement, or a 10 MHz reference signal is applied for frequency synchronization. The trigger thres-
old is similar to that of TTL signals. The level for the reference signal must be greater than 10 dBm.
Switchover between external trigger input and reference input is via the SETUP key.
DC connector for external power supply (on the right-hand side of the carrying handle).
The DC connector is used to supply the R&S FSH with power from the AC/DC adapter and to charge
the R&S FSH internal battery. The input voltage for the instrument must be between 15 V and 20 V.
Power consumption is approx. 7 W.
The battery can also be charged from a cigarette lighter socket in a vehicle. The adapter is available as
an R&S FSH accessory (R&S FSH-Z21, order no. 1145.5873.02).
Caution! While the battery of the R&S FSH is being charged via the 12 V Car Adapter
R&S FSH-Z21, the car adapter must not be connected to the vehicle's ground (for
example, via the R&S FSH's RF connector or the power sensor) under any
circumstances.
Headphones connector (on the left-hand side of the carrying handle).
A3.5 mm jack is provided for headphones. The internal impedance of the connector is approx. 10 E.
RS-232-C optical interface
(on the right-hand side of the R&S FSH, can be accessed by folding out the stand).
The RS-232-C optical interface is for connecting a printer or PC. The USB Optical Cable R&S FSH-Z37
(supplied with the R&S FSH) or the RS-232-C Optical Cable R&S FSH-Z34 available as accessory are
used to make the connection. The optical connection prevents measurements as a result of interference
from these devices. If you use the R&S FSH-Z37 USB optical cable, you need to install a software
driver on your PC. The CD-ROM, which is supplied with the R&S FSH, includes both the driver and the
installation instruction.
Use the Serial/Parallel Converter R&S FSH-Z22 for printers with a parallel interface.
Connector for power sensor
The connector has been especially configured for Rohde & Schwarz power sensors. The connector is
used to power the sensor and to transfer data via the power sensor’s interface. If the R&S FSH-Z2
(VSWR bridge up to 3 GHz) or R&S FSH-Z3 (VSWR bridge up to 6 GHz) is used, it is controlled by this
connector.

Tracking generator output (models 1145.5850.13, 1145.5850.23 and 1145.5850.26 only)
Connect the tracking generator output to the DUT via an N connector. The nominal output level is
-20 dBm (100 GW). With the R&S FSH3 model 1145.5850.23, the level can be switched between
-20 dBm and 0 dBm (1 mW). Up to 3 GHz, the R&S FSH6 model 1145.5850.26 supplies an output level
of -10 dBm; above 3 GHz, the level is -20 dBm.
The output is AC-coupled and a voltage that does not exceed the voltage specified on the
housing can be fed into the output; if this voltage is exceeded, the output may be
destroyed.

R&S FSH Charging the Battery
1145.5980.12 1.11 E-12
Charging the Battery
The R&S FSH is fitted with a nickel metal hydride battery. Under the following conditions, the battery
operating time is approx. four hours: fully charged battery, room temperature, tracking generator
switched off.
Note: The battery in the R&S FSH is not charged when it leaves the factory. It must therefore be
charged after delivery.
When stored over an extended period, self-discharging reduces the battery charge. The battery should
therefore be charged before use if it is going to be the sole power source for a long period of operation.
The charging status of the battery is displayed by a
symbol that looks like a battery in the middle of the
screen above the row of softkey labels. If the battery is
fully charged, the entire battery symbol is white. As the
battery discharges, the white coloring disappears in
five steps until just the battery outline indicates that the
battery is flat.
Battery charge-level symbol
The battery is charged via the included power supply unit, which is connected to the jack on the right-
hand side of the carrying handle.
If required, equip the power supply unit
with the country-specific plug. Remove
the plug from the power supply unit
toward the front and firmly connect the
appropriate plug to the power supply
unit.
AC supply plug
Power supply
DC power jack
For rapid charging, be sure to switch off the R&S FSH during charging. The charging time is approx.
seven hours.
If the R&S FSH is switched on, the charging current for the battery is reduced by the current drain of the
R&S FSH, which means the battery might not be charged.
To prevent the battery from discharging unnecessarily, the R&S FSH has an automatic cut-off or auto
power down mode that is activated if no entry is made for a definable period of time (5 minutes or
30 minutes).
The auto power down mode is deactivated in the default setting.

Charging the Battery R&S FSH

R&S FSH Selecting the Instrument Default Setup
1145.5980.12 1.13 E-12
Selecting the Instrument Default Setup
The PRESET key sets the R&S FSH to the default setup. This allows a new configuration based on
defined measurement parameters to be entered, without parameters from a previous setting
unintentionally still being active.
Press the PRESET key.
The R&S FSH is set to the default setup. The span depends on the model. With the R&S FSH3, it is
3GHz; with the R&S FSH6, 6 GHz, and up to 18 GHz with the R&S FSH18.
If certain parameters are always to deviate from the default setup for a specific application, it is also
possible to select a user-defined default setup, which is then automatically set with the PRESET key.
This is useful, for example, if the measurement is always made with a 75 matching pad. When the
PRESET key is pressed, the R&S FSH always selects 75 as the input impedance for the user-
specific default setup. The user-defined default setup is generated by manually entering the desired
parameters and saving the setting as a data set. This data set can subsequently be declared the preset
settings with the aid of the R&S FSH View software.
The data set designated as the preset settings becomes the default setup of the R&S FSH as follows:
Press the SETUP key.
Press the GENERAL softkey.
Select PRESET SETTINGS from the menu using
the cursor keys or the rotary knob.
Confirm your choice with the ENTER key or the
GENERAL softkey.
The submenu for selecting the default setup opens. Either DEFAULT or CUSTOM can be selected.
Select CUSTOM from the menu using the cursor
keys or the rotary knob.
Confirm your choice with the ENTER key or the
GENERAL softkey.
The parameters defined in the data set for the default setup are now used as the preset settings.
If no user-specific default setup is defined, CUSTOM is inactive and cannot be selected.
The data set defined as the user default setup can be viewed using the R&S FSH's recall function.
Press the SAVE/PRINT key.
Press the RECALL softkey.
All stored data sets are displayed.
The status of the data set is indicated in the status
field:
