FM Test Receiver Instruction Manual

Connections

RF Input Socket

The received signal of the antenna or of the cable network is fed in here

(BNC coaxial socket).

The remote feeding voltage (for LNB) is adjustable from 5 V

to 20 V

and can be switched off. When the LNB voltage is switched on, the LED

next to the RF input socket flashes.

Make sure that there are

• no voltage level over 120 dBµV,

• no positive DC voltage over 22 V

• no negative DC voltage and

• no AC voltage

adjacent to the RF input socket.

Non-compliance with these warning notices may destroy the input circuit.

External DC Voltage Supply

The MSK 25 may either be mains operated or battery operated (batteries

built-in). The external voltage supply is carried out via the DC socket at

the right side of the MSK 25 box, with the wall power supply and the

charger, both included in delivery. Sustained continuous operation (incl.

MPEG option) is possible in case of an LNB power consumption of no

more than max. 300 mA. Additional current will be drained from the

battery built-in if the power consumption is higher than that.

Make sure that

• only the wall power supply included in delivery is used.

• the wall power supply is not connected to the instrument but for

voltage feed. Otherwise the battery of the MSK 25 will be discharged!

Scart Output

The video and audio signals are emitted on the Scart socket on the right

hand side of the MSK 25, for rating purposes on an external monitor.

There are no inputs!

Misallocations of the connections may cause damage or destruction

of the instrument!

RS 232 Interface

Software updates are possible via RS 232 interface.
