Keysight N5171B EXG 3GHz RF Analog Signal Generator

Keysight N5171B EXG 3GHz RF Analog Signal Generator

The Keysight N5171B EXG X-Series 3 GHz RF Analog Signal Generator is an electronic test instrument that produces controlled radio-frequency signals. Engineers and technicians use these signals to test receivers, RF components, and communication equipment. The 3 GHz configuration covers frequencies from 9 kHz to 3 GHz, providing a versatile signal source for laboratory, manufacturing, and service applications.

Its primary function is to generate a stable RF signal at a selected frequency and output level. By applying this known signal to a device under test, users can evaluate how the device responds under controlled conditions. Typical tasks include checking receiver sensitivity, measuring component response, and troubleshooting signal-processing circuits.

With the appropriate installed options, the N5171B supports amplitude modulation (AM), frequency modulation (FM), phase modulation, and pulse modulation. These capabilities let users vary the RF signal to reproduce different operating conditions and evaluate receiver performance. Internal modulation sources and external inputs provide flexibility when setting up tests.

The instrument can be operated from its front panel or integrated into an automated test system. Programmable control allows users to repeat test sequences and change signal settings consistently, making it useful for production testing and routine verification. Keysight designed the EXG series with manufacturing throughput and equipment uptime in mind.

In practical use, the N5171B gives technicians a predictable signal source for finding faults, verifying performance, and comparing results. Its adjustable frequency, output level, and optional modulation functions support a wide range of RF testing needs. The exact capabilities of an individual unit depend on its installed frequency, modulation, and performance options.
