Table 2-1. 1MHz sine wave spectrum test results

Question

1. What is the spectrum of a theoretical sine wave and why is it

different with the actual measured one?

2. What is the frequency domain feature of the analyzed signal?

Caution

1. The output power should not exceed the rated input of the

spectrum analyzer, otherwise the spectrum analyzer will be
damaged.

2. When using the RF cable to make a connection, be sure to

tighten the connector.
