The 70900A local oscillator is a 1/4 width module that consists of three eleiments: a local oscillator, a controller, and a video processor.
The local oscillator supplies a swept signal with a frequency range of 3.0 to 6.6 GHz for use by the front end modules, tracking generator, external mixer interface module, or any other module or device requiring the signal. For spans ≤10 MHz, the sweep is fully synthesized using fractional-N techniques while for spans >10 MHz, lock-and-roll tuning is used.
The video processor digitizes the video signal received from the IF module and processes this signal using normal (Rosenfell), positive peak, negative peak, or sample detection.
The controller contains the system firmware, which controls and coordinates measurements. Other system modules (such as, front ends, IF, tracking generator) are slave modules that are controlled by the local oscillator module.
The following switches ares used for HP-IB control:
