• Step sweep modes
• GPIB
• Call for avaiability of options

The ESG-AP and ESG-A Series provide comprehensive analog modulation capabilities, including AM, FM, phase and pulse modulation. They also have built-in step sweep features and a versatile function generator.

Choose the ESG-AP Series (E4423B-26B) for outstanding phase noise performance and analog modulation features for all general purpose test needs. Choose the ESG-A Series (E4400B-22B) for the same analog capabilities with slightly lower spectral purity.
