RF Communication and Signals Experiments
Experiment
principles
Set the waveform on the GRF-1300A and measure the
harmonic spectrum. Switch to a different waveform and
measure the harmonic spectrum. Compare the differences. The
relationship between the time domain and the frequency domain
has already been introduced in chapter 3. We won’t repeat it
again here.
Experiment
contents
We will become familiar with using a spectrum analyzer
and how to use the GRF-1300A by analyzing the spectrum of a
simple triangle and square wave signal.
Experiment
steps
1. Turn on the GRF-1300A and the GSP-730.
2. Set the GRF-1300A baseband as follows:
• Waveform: triangle
• Frequency: 1MHz.
• Turn the input amplitude knob clockwise to the end.

3. Connect the baseband signal from the output port on the
GRF-1300A to the input terminal on GSP-730 with the RF
cable.
4. Set the GSP-730 as follows:
• Center frequency: 15MHz
• Start frequency: 0kHz,
• Stop frequency: 30MHz, Span: 30MHz
