WebThis paper presents a frequency-modulated optical signal generator in the THz band. The proposed method is based on a fast optical frequency sweep of a single narrowband laser diode used together with an optical fiber interferometer. The optical frequency sweep using a single laser diode is achieved by generating short current pulses with a high amplitude, … WebMay 15, 2024 · PLL/DDS Frequency Sweep. Venkatesh2014 on May 15, 2024. Hi, I am trying to make a small automated test equipment where i have a requirement to generate a sweep signal from 130MHz to 160MHz in steps of 25/12.5KHz for testing. The complete sweep time should be less than 5 seconds for the whole band. I tried achieving the same with …

Webfrequency and the phase information of a signal. The phase information the FFT yields is the phase relative to the start of the time-domain signal. For this reason, you must trigger from the same point in the signal to obtain consistent phase readings. A sine wave shows a phase of –90° at the sine wave frequency. A cosine shows a 0° phase.
