Description

Flexible Analog Modulation

The Keysight MXG ATE vector equipped with Option UNT can generate internally or externally driven AM, FM, and øM signals.

Typical application
Option UNT is recommended for testing analog communications systems, simulating unwanted modulation on a carrier, or simulating interfering signals when performing receiver tests.

Additionally, Option UNT simulates telemetry tones for satellite receiver tests requiring FM or satellite communication traffic with the addition of an external modulation source for frequency shift keying (FSK).

Ideal for radar receiver tests, Option UNT generates complex signals consisting of simultaneous AM, FM, or pulse modulation (Option UNU) to simulate real-world threats or frequency-stable chirp signals to test radar receiver range resolution.

This option can be added as a product upgrade.
