Agilent / Keysight N5183B MXG X-Series Microwave Analog Signal Generator, 9 kHz to 40 GHz

The Keysight N5183B MXG X-Series Microwave Analog Signal Generator delivers high-performance signal generation across 9 kHz to 40 GHz, addressing demanding RF and microwave test requirements in radar, satellite communications, and wireless device validation. This instrument combines wide frequency coverage with precise signal control: 0.001 Hz resolution, rapid frequency switching (≤900 µs in list/step mode), and configurable output power to +21 dBm. Phase noise performance reaches -124 dBc/Hz at 10 GHz with 10 kHz offset, while harmonic suppression maintains -55 dBc levels across the band.

The N5183B supports AM (DC to 100 kHz), FM (1 to 128 MHz deviation), pulse modulation (20 ns minimum width), and CW blocking. Five internal function generators enable narrowband chirp and radar antenna scan simulation. Sweep capabilities include step mode (2 to 65,535 points) and list mode (1 to 3,201 points) with adjustable dwell times from 100 µs to 100 s. Frequency switching reaches typical speeds of ≤600 µs in list mode and ≤1.15 ms in CW mode.
