Part 2/7:
Firstly, a notable signal generator was identified operating within the range of 55 to 220 megacycles, highlighting its function as a basic obstacle scope type, which allows for standard specifications in RF applications.
High Frequency and Low Frequencies
Further examples include a high-frequency switch with four ports, indicating a versatile configuration that can channel signals from one central port to multiple outputs. Additionally, a range of frequencies was described, including a 300-megahertz signal generator operating from 180 to 400 megacycles, further extending the capabilities of RF applications.
