Keysight Technologies E4428C

The E4428C 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 E4428C 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.

Signal Characteristics:

• 250 kHz to 3 or 6 GHz (.01 Hz resolution)
• -136 to 17 dBm @ 1 GHZ and 10 dBm @ 6 GHz output power
• +/-0.5 to +/-0.9 dB level accuracy (> -110 dBm)

Spectral Purity:

• -134 dBc/Hz SSB phase noise @ 20 kHz offset, 1 GHz carrier (typ)
• Enhanced phase noise performance (Option UNJ) ships standard
• High-stability timebase: oven-controlled crystal oscillator (OXCO)

Modulation and Sweep:

• AM, FM, ØM, and pulse modulation
• DC to 10 MHz FM modulation rates, maximum deviations up to 8 MHz
• Dual internal function generators: sine, square, ramp, triangle, noise, DC, pulse, swept sine, dual sine
• Step and list sweep (frequency and power)

Automation and Communication Interface:

• 10BaseT LAN and GPIB
• SCPI and IVI-COM drivers
• Backwards compatible with all ESG signal generators
