SWY1058 standard signal source

SWY1058 standard signal source is an economical RF standard signal generator with a wide frequency range: from 0.1MHz to 110MHz, covering broadcast channels. The output level can range from a few microvolts to the volt level. And the SWY1058 standard signal source outputs high fidelity and low noise waveforms. The SWY1058 standard signal source has lower noise voltage than digital synthesis signal sources, especially at the microvolt level. The SWY1058 standard signal source uses LED digital tubes and electric meters to quantitatively display the frequency value, amplitude, and modulation degree of the generator, meeting the requirements of standard signal source configuration. With a high cost performance ratio, the SWY1058 standard signal source has become the preferred signal source for broadcasting communication, production maintenance, and teaching experiments.

characteristic:
◎ Five digit LED digital display carrier frequency
Four digit LED digital display output amplitude (before attenuator)
8 sets of attenuators and digital display value combinations can quantitatively determine the output level value
◎ Output standard signals ranging from μ V to V. The configured 50 Ω terminal load facilitates system connection
◎ Switching between 0.1MHZ and 110MHZ is only one level, making frequency adjustment very convenient. Set two levels of thickness
◎ With AM and FM external modulation functions, it can form a transmitting signal source
◎ 1KHZ and 400HZ low distortion audio output signal sources
The FM frequency offset can be adjusted and the parasitic amplitude modulation is small, which is the characteristic of this signal source
◎ Quantitative display of modulation status
The amplitude of AM modulation can be adjusted from 0 to 100%. Due to the use of newly developed modulator integrated circuits from abroad, the amplitude modulation distortion is very small
