The HP 8663A derives exceptional RF performance from an indirect frequency synthesis technique that results in frequency resolution of 0.1 Hz from 10kHz to 640 MHz, 0.2 Hz from 640 MHz to 1280 MHz and 0.4 Hz above 1280 MHz. Output level accuracy is held to ± 1 dB using microprocessor correction. This makes the HP 8663A an ideal generator for performing precise receiver sensitivity tests either manually or in automated systems. The HP 8663A offers versatile phase-locked AM/FM using either internal 400 Hz and I kHz rates or externally applied modulating signals, which can be either dc or ac coupled. Several different modes of simultaneous modulation (such as AM + FM or FM + FM) are possible. Fast frequency switching combined with microprocessor control gives the HP 8663A a powerful sweep capability. Automatic, single, and manual modes are available for both linear and logarithmic sweeps with user-selectable step size and number of steps. Specifications.
