California Instruments 800T - Precision Oscillator Simple Type: Instrumentations

The California Instruments 800T series of plug-in oscillators are designed for applications that require a sweep through the bandwidth without steps. The 800T features a large calibrated vernier scaled dial to select the desired frequency. The continuously variable 800T series oscillators include both multiband wide-range units and single-band narrow-range units. The multi-phase units include single-phase, two-phase, and three-phase models. The series also includes "Open Delta" models. A single three-phase oscillator drives two power sources of equal VA rating. The oscillator provides two equal amplitude drive voltages at a 60° phase angle. The power sources are loaded in such a way that the third load phase is necsessarily at a 60° angle with the other two loads, forming a delta. Each two-phase and three-phase oscillator contains an amplitude control to obtain simultaneous variation of the amplitude of each phase.
