used to adjust the frequency of the baseband signal. The
baseband module is adjustable in 10kHz steps.

• WAVE Select is used to select three different baseband

waveforms. When the waveform is selected, the
corresponding LED light will be lit up.

• The Reset button is used to reset the GRF-1300A. When

reset, the GRF-1300A will output a 0.10MHz sine wave
baseband signal and a carrier signal with a frequency
880MHz.

• The output port is used to output the set baseband signal.

• The four-digit display is used to display the frequency of

the output baseband signal.

• TP4 (test point 4) is used to used to monitor the output

signal from the output port.

• The potentiometer knob is used to adjust the voltage of the

output baseband signal. Turn clockwise to increase the
amplitude and turn anticlockwise to decrease its
amplitude.

module can be used to adjust the frequency of the carrier. The
carrier can be adjusted in 1MHz steps.
