Model Number: OFL250-50U-ENG
The spectrum analyzer permits the detection of spectrum components of electrical signals in the frequency range of 0.15 to 1050 MHz for Models 2625 and 2630 and 0.15 to 500 MHz for Models 2615 and 2620. The detected signal and its content have to be repetitive. In contrast to an oscilloscope operated in Yt mode, where the amplitude is displayed on the time domain, the spectrum analyzer displays amplitude on the frequency domain (Yf). The individual spectrum components of “a signal” become visible on a spectrum analyzer. The oscilloscope would display the same signal as one resulting waveform
