GRF-1300A User Manual and Teaching Materials
For the last two steps, the span is quite large, and may produce
some errors. To find the second and third harmonic, you may
need to fine-tune the frequency. Record the results in table 4-2.
Measure the RF
phase noise. 1. Turn on the GRF-1300A and the GSP-730.
2. Set the GRF-1300A RF Synthesizer/FM as follows:
• Carrier frequency: 875MHz
Step1
3. Connect the RF/FM 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: 875MHz
• Span: 1MHz
• Reference level: 0dBm
• RBW: Auto (default state is 50kHz)
