The 6070A Synthesized Signal Generator combines the precision resolution and settability of a synthesizer with the low-noise performance of the best open-loop signal generators. The unit is programmable and directly compatible with GPIB/IEEE-488-1978. The 6070A can perform sophisticated tests and measurements rapidly and with great precision. On VHF or UHF receivers you can measure selectivity, sensitivity, intermodulation distortion, AM rejection, AGC response, audio hum, noise and distortion, and SINAD ratio. Or you can align a discriminator or check IF response using the digital sweep feature. The instrument covers the frequency range of 0.2 to 519.999 999MHz with a resolution of 1Hz.
