SIT9003AI-1-33EB Working Principle

The working principle of the SIT9003AI-1-33EB is based on the use of a circuit that produces an output signal with a stable frequency and frequency sweeps. This signal is then used to control the frequency of the signal sent out by the oscillator. The output frequency of the oscillator can be set and adjusted using a set of digital inputs, which are connected to the signal generator via a serial interface.

The signal generator contains a phase-locked loop (PLL) circuit with a varactor as the phase adjustment device. The varactor is used to adjust the frequency output of the signal generator. The PLL circuit uses a phase detector to detect the error signal between the actual desired frequency and the measured frequency of the output signal. This error signal is then used to adjust the varactor, which in turn adjusts the frequency of the output signal.

In addition to the PLL circuit, the digital control interface on the SIT9003AI-1-33EB programmable oscillator provides users with a variety of other control options such as frequency programming sync, reference voltage adjustment, and synchronous amplitude adjustment. By adjusting these parameters, the user can fine-tune the output signal of the oscillator to achieve the desired frequency, shape, output power, and phase stability.
