Details
It passes its power on self tests and the RF output has been tested.
Original Manufacturer Description:
The E4428 ESG analog signal generator delivers outstanding spectral purity, level accuracy, output power, and analog modulation performance up to 3 or 6 GHz for all general-purpose test needs. This makes the E4428 ESG a superb choice for general-purpose tests requiring CW, AM, ØM, and FM receiver and component test signals in the cellular, ISM, and UNII frequency bands.
