Agilent 8664A Signal Generator

The Agilent 8664A model is a signal generator that is suited for essential receiver testing up to 3.0 GHz. SSB phase noise is a critical determination of this signal generator on the off chance that it is to be utilized for measuring the nearby channel selectivity of a receiver. On the off chance that the phase noise of the signal generator is too high at recurrence counterbalances equivalent to the channel dividing, the test outcomes may demonstrate a failure of the receiver when it is really working appropriately. In the event that the selectivity is ≥ 90 dB, the 8644B (or Option 8664A-004) is suggested.

This model is fit for <-140 dBc/Hz run of the mill SSB phase noise at 20 kHz counterbalance at 1 GHz with Option 004, <-100 dBc nonharmonic spurious to 2 GHz lessens mistake when testing spurious insusceptibility of receivers AM, FM, and discretionary pulse modulation. Output level exactness is a blend of temperature variety, levelness over recurrence, and the signal generator's inward attenuator and identifier correctnesses.

Because of radios ending up more sensitive and working at higher frequencies, the customary two-turn circle estimation of RF leakage has turned out to be lacking. To conquer the weaknesses of the two turn circle, Agilent has built up another estimation system utilizing thunderous dipole reception apparatuses, which is 20 to 25 dB more sensitive than the two-turn circle technique. Agilent has possessed the capacity to diminish the level of emanated discharges in its fresher flag generators through inventive outline and bundling. Understanding that not all applications require the most minimal conceivable discharges, Option 010 (i.e., 86xxx-010) is accessible on these execution signal generators.
