The Keysight N5173B EXG is a microwave analog signal generator that balances performance, cost, and size to provide excellent value for broadband RF and microwave testing. Designed for component test, general-purpose microwave applications, and local oscillator (LO) substitution, it offers a standard frequency range starting at 9 kHz and up to 40 GHz depending on the selected frequency option. The N5173B features step and list sweep capabilities, versatile analog modulation (AM, FM, PM, and Pulse), and standard connectivity options including LAN (LXI Core), USB, and GPIB.
