Self-contained flexible analog modulation
The E8663D PSG RF analog signal generator equipped with Option UNT can generate internally or externally driven AM, FM, and M signals. The internal modulation generator can also be used as a low frequency (LF) output source that provides a replica of the modulation signal or acts as a basic function generator.
Typical applications
Option UNT is recommended for satellite receiver tests requiring wideband FM for simulating telemetry tones or when using an external modulation source for frequency shift keying (FSK) to simulate satellite communication traffic. Option UNT is also strongly recommended for radar receiver tests where complex signals consisting of simultaneous AM, FM, or pulse modulation are required to simulate real-world threats or when frequency-stable chirp signals are needed to test a radar receiver's range resolution.
This option can be added as a product upgrade.
