Power supply
The teaching kit has two USB interfaces to supply it with power, a micro USB interface and a
mini USB interface. You can use both interfaces to supply the teaching kit with power.
A USB cable for the micro USB interface is included in the delivery. If you want to use the mini
USB interface for power supply, you have to use a corresponding cable.
Select the USB interface you want to use as a power supply with the jumper
(5).
Position 1: Selects the micro USB interface as the power supply.
Position 2: Select the mini USB interface as the power supply.
The ratings of the interfaces depend on the application.
●
For measurements with an inactive baseband circuitry, the rating is 5 V DC at 450 mA.
Use the USB cable delivered with the teaching kit to connect it to another USB interface.
You can use the USB interfaces on the R&S
®
FPC as the power source, for example.
●
For measurements with an active baseband circuitry, the rating is 5 V DC at 750 mA.
Using the baseband connectors requires an external power supply with a rating of 5 V DC at
1 A. If an external power supply is required, the LED above the mini USB interface is
illuminated.
Baseband state
If you want to use the I/Q modulator or demodulator, you have to activate the baseband signal
path on the DIP switch (8).
Switch 7 controls the baseband input state. Move it into the "on" position if
you want to use the baseband connectors. If you turn on the baseband,
you have to to use an external power supply as described under "Power
supply".
Note that switch 1 has to be always "On". The other switches on this DIP switch are not
supported.
