Chapter 1 Overview
Instrument introduction
JDS2800 series function generator can generate multiple waveforms such as sine wave,
square wave, triangle wave, pulse wave, and arbitrary wave. The frequency range up to
60MHz, with duty cycle adjustment, sweep frequency, frequency signal frequency and
counter function, and the output signal, amplitude, and frequency can be displayed
simultaneously. The series signal generator has excellent amplitude and frequency
characteristics, the appearance of this instrument is exquisite and beautiful.
This instrument is widely used in factories, schools, research institutes and laboratories.
The model description
This series of instruments are divided into three models, the main difference is the
maximum frequency of sine wave output, as described below:
