6.2 Frequency Generation

The module can generate frequencies from 35MHz to 4.4GHz. The output type varies with frequency:

• 2.2GHz - 4.4GHz: Fundamental (sine wave) output.
• 35MHz - 2.2GHz: Fundamental division (square wave) output.

The software allows for precise frequency setting, including point frequency, sweep, and frequency hopping. Stepping can be as fine as 1KHz, or 0.1KHz depending on the crystal frequency.
