E4428C Analog Signal Generator Overview
Modes of Operation
Modes of Operation
The ESG signal generator provides three modes of operation:
• continuous wave (CW)
• swept signal
• analog modulation
Continuous Wave
In this mode, the signal generator produces a CW signal. The signal generator is set to a single frequency
and power level.
Swept Signal
In this mode, the signal generator sweeps over a range of frequencies and/or power levels. Both list and step
sweep functionality is available.
Analog Modulation
In this mode, the signal generator modulates the CW signal using one of four analog modulation types:
•AM (two paths)
•FM (two paths)
• ΦM (normal and high bandwidth)
• Pulse modulation
