FG-300 Signal Generator Manual

1. Product Introduction

1.2 Product Features

Using low temperature drift crystal oscillator, high precision DDS frequency synthesis technology, high

frequency stability, resolution up to 0.001HZ, at low frequency accuracy up to 0.001HZ

Can be up to 13 kinds of waveform output, to meet different needs

Color 1.8TFT LCD display, digital keyboard direct input frequency, intuitive and convenient operation.

With timing shutdown, signal light brightness adjustment, screen backlight brightness adjustment.

1.1 Product overview

FG-300 is the multifunctional, high-precision, portable signal generator, which can generate sine wave, square

wave, triangle wave, forward sawtooth wave, reverse sawtooth wave, electrocardiogram, half wave, Loren,

Gaussian, Sinc, Exponential rise, exponential fall, and 7.83HZ Schumann wave and other waveforms. The onboard

spiral antenna can be used as a Schumann wave generator, can be widely used in electronic research and

development, production testing, education and teaching, maintenance, audio testing and other fields.

All setting parameters can be automatically saved, and there is no need to set them in the next startup.

Project Parameters

2.1 frequency range: sine wave 0.001Hz-200kHz (where the output amplitude is flat to 100 kHz, the output

amplitude will decrease and the distortion will increase with the further increase of the frequency), and other

waveforms will be 0.001Hz-20kHz (but the upper limit of adjustable frequency is not limited. If the requirements for

distortion and shaking are not high, the use frequency can be further increased).

2.2 waveform types: sine wave, square wave, triangle wave, forward sawtooth wave, reverse sawtooth wave,

electrocardiogram, half wave, Loren, Gauss, Singh, exponential rise, exponential fall, and 7.83HZ Schumann wave

2.3 output amplitude: 2. 5V

2.4 output impedance: 330 ohms

2.5 display: 1.8 inch TFT display

2.6 supply voltage: USB-TYPE C

2.7 dimensions: length 125MM width 95MM high 18mm

3.4 basic operation

Power On/Off

In the shutdown state, long press this key for more than 3 seconds will boot. In the power-on

state, it will shut down after long pressing for 3 seconds.

In the boot state, short press this key to turn off the screen, but the signal is still normal

output, in the second short press this key to turn on the screen

Enter the frequency as a decimal point. In the waveform output state, press this key to stop

the signal output

Frequency parameter setting

Just press the input corresponding number and decimal point combination, and then press the OK key to output

the corresponding frequency, for example, 7.83HZ only need to press 7.83√

Waveform switch key, you can switch the output waveform type.

The timing shutdown key can be adjusted to shut down after 1-24 hours, and the display ∞

indicates that it is always on.

Screen backlight adjustment, B _01-B_10 B _01 is the darkest, B _10 is the brightest.

Signal lamp brightness indication, F_00 signal lamp is not on (off) F_01- F_09 adjusts the

signal lamp brightness.

F_01 is the darkest, F_09 is the brightest. (When F_01, when the display is on, the indicator

flashes with the lowest brightness, and the display is off and the indicator is off)
