An accurate and simple way of simulating microwave fade conditions is by using the 3708A Noise and Interference Test Set. It lets you inject noise of known spectral density into the IF section of a microwave radio link receiver to establish a demanded carrier-to-noise ratio. The radio IF carrier power is sampled by the 3708A at the point of noise rejection and the noise density adjusted automatically to maintain a constant carrier-to-noise ratio in the presence of receiver carrier laevel variations.

FEATURE & SPECIFICATIONS:

• Highly accurate wideband noise source covers all common link IFs
• Tracking mode maintains constant C/N rating under carrier fading conditions
• Broadband interference facility with or without noise injection stresses the radio deterministically
• C/N & C/I Measurement Modes
• High stability reference tone
• Auto-calibration for enhanced accuracy
