R&S FSH3-TV Putting into Operation
Setting up the Instrument
he handheld TV Analyzer R&S FSH3-TV has been designed for operation in labs as well as for on-site
T
use for service and maintenance applications.
For any application, the R&S FSH3-TV 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 FSH3-TV can either be laid flat or it can be
propped up using the fold-out support at the back.
The R&S FSH3-TV can be laid flat for operation from
above. Because the grip is slightly raised at the back,
the R&S FSH3-TV 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 FSH3-TV 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 FSH3-TV 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.
2111.7040.12-04.00
1.3
Putting into Operation R&S FSH3-TV
Switching on the TV Analyzer
he R&S FSH3-TV can be powered using either the included power supply unit or internal battery.
T
When fully charged, the built-in nickel metal hydride battery provides an operating time of three to four
hours. On delivery, the battery in the R&S FSH3-TV may be flat. Therefore, it must be charged before
the R&S FSH3-TV can be used. If the instrument is switched off, the charging time is about four hours.
When the adapter is used, the R&S FSH3-TV’s battery is charged simultaneously. However, charging
takes much longer if the R&S FSH3-TV is switched on. A battery that is almost flat should therefore be
charged when the R&S FSH3-TV is off.
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!
In vehicles, the battery can be charged from the cigarette lighter socket using the R&S FSH-Z21 cable.
Caution!
Only the supplied power supply unit – the R&S FSH-Z33 – may be used to power the
R&S FSH3-TV 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.
It is strictly forbidden to operate the R&S FSH3-TV via the cigarette lighter socket while
the vehicle is in motion or the engine is running. In these cases, the R&S FSH3-TV must
be off.
While the battery of the R&S FSH3-TV 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 RF connector) under any circumstances.
To switch on the R&S FSH3-TV, press the yellow button
To indicate that it is connected to the AC supply, the
R&S FSH3-TV displays a connector symbol in the
middle of the display above the softkey labels.
When the R&S FSH3-TV 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 FSH3-TV 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.

R&S FSH3-TV Putting into Operation
TV Analyzer Connectors
he R&S FSH3-TV has the following connectors:
T
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!
Multifunctional BNC connector (EXT TRIG/REF CCVS/TS-ASI OUT)
The multifunctional BNC connector (EXT TRIG/REF CCVS/TS-ASI OUT) is used as an input and output
connector for a number of R&S FSH3-TV functions. The connector is controlled via the SETUP –
HARDWARE SETUP key.
• Trigger signal input
Applies an external trigger signal to start a measurement. The trigger threshold is based on the
trigger threshold of TTL signals. The input impedance is approx. 1 kB.
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.
• Video trigger input
Applies an external video signal for triggering to a TV line. The video amplitude must be in the
range from 0.5 V to 2.0 V. A composite synchronous signal can also be applied for triggering. The
input impedance is approx. 1 kB.
• 10 MHz reference input
Applies a 10 MHz signal for external frequency synchronization. The level for the reference signal
must exceed 10 dBm. The input impedance is approx. 1 kB.
• Video signal output
Output for the demodulated video signal in the analog TV receiver mode. The output is suitable for
connecting a video analyzer (e.g. the R&S VSA) or a monitor. With standard-compliant modulation,
the output signal has a video amplitude of 1 V at 75 B. The black level is connected to the DC
voltage level of 0 V. The source impedance is 75 B.
• TS-ASI output
Output for the TS-ASI signal in the digital TV receiver mode. The output is suitable for connecting
an MPEG transport stream analyzer such as the R&S DVMD, R&S DVM 400, R&S DVM 100 or
R&S DVM 50. The output amplitude is 0.8 V at 75 B. The source impedance is 75 B.
2111.7040.12-04.00
1.5
Putting into Operation R&S FSH3-TV
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 FSH3-TV with power from the AC/DC adapter and to
charge the R&S FSH3-TV's internal battery. The input voltage for the instrument must be between 15 V
and 20 V. Power consumption is between 7 W and 10 W, depending on the operating mode.
The battery can also be charged from a cigarette lighter socket in a vehicle. The adapter is available as
an R&S FSH3-TV accessory (R&S FSH-Z21, order no. 1145.5873.02).
Caution!
Headphones connector (on the left-hand side of the carrying handle)
A 3.5 mm jack is provided for headphones. The connector is also used as an audio measurement
output in the analog TV receiver mode.
Optical interface
(on the right-hand side of the R&S FSH3-TV; can be accessed by folding out the stand)
The optical interface is for connecting a PC via a USB connector. The Spare USB Optical Cable
R&S FSH-Z37 that comes with the R&S FSH3-TV is used to make the connection. The CD-ROM, which
is supplied with the R&S FSH3-TV, includes both the driver and the installation instruction.
While the battery of the R&S FSH3-TV 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 FSH3-TV's RF connector or the power sensor) under any
circumstances.
The optical connection prevents spurious measurements as a result of interference from these devices.
Use the Serial/Parallel Converter R&S FSH-Z22 for printers with a parallel interface. Use the Spare
RS-232-C Optical Cable R&S FSH-Z34 for connecting a PC or for printers with an RS-232-C interface.
Connector for preselector, VSWR bridge, power divider and power sensor (CONTROL
INTERFACE)
The connector has been especially configured for the Preselector R&S FSH-TV-Z60 and the VSWR
Bridge and Power Divider R&S FSH-Z2 as well as for Rohde & Schwarz power sensors. The connector
is used to power and control these components and to transfer data.
Tracking generator output (gen output)
Connect the tracking generator output to the DUT via an N connector. The output level can be set
between -20 dBm and 0 dBm.
Caution!
The output is AC-coupled and a voltage that does not exceed the voltage stated on the
R&S FSH3-TV housing can be fed into the output; if this voltage is exceeded, the output
may be destroyed.

R&S FSH3-TV Charging the Battery
Charging the Battery
The R&S FSH3-TV is fitted with a nickel metal hydride battery. The operating time is three to four hours
at room temperature if the battery is fully charged.
Note: The battery in the R&S FSH3-TV 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.
The battery is charged via the included power supply unit, which is connected to the jack on the righthand 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.

For rapid charging, be sure to switch off the R&S FSH3-TV during charging. The charging time is
approx. four hours.
If the R&S FSH3-TV is switched on, the charging current for the battery is reduced by the current drain
of the R&S FSH3-TV, which means the battery might not be charged.
To prevent the battery from discharging unnecessarily, the R&S FSH3-TV 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.
