1．Introduction to parts：

Jumper cap:

1. P1 jumper cap, switching frequency output gear

2. S1 switch sine wave or triangular wave or square wave orsawtooth, reverse sawtooth, output

Blue output terminal:

1. OUT1: blue terminal output offset amplitude Adjustable wave

2. OUT : blue terminal output max038 Pin 19 out Unadjustable (offset amplitude) waveform

3. SYNC: The TTL-compatible SYNC output from the internal oscillator maintains a 50% duty cycle—regardless of the duty cycle of the other waveforms—to synchronize other devices in the system

3. GND: signal ground

Potentiometer adjustment

1. DUTY: Adjust the rectangular wave duty cycle, you can make triangular wave sawtooth wave

2. FREQ: Frequency adjustment (with JP2 jumper cap)

3. OFFSET: Signal DC bias adjustment

4. AMP: sine wave, triangular wave, forward sawtooth wave, reverse sawtooth amplitude adjustment

2．Using the step：

1. Plug in the power supply, the power supply is 5.5 * 2.1 port, the polarity is the hole is positive, the outer ring is negative. The supply voltage is 9-15V. More than 15V may damage the instrument

2. How to output standard sine wave, square wave, triangle wave?

Insert the W5 jumper cap into the 50% DUTY position. Connect the oscilloscope to OUT1 or OUT. Press the S1 button to switch the waveform output.

3.How to output sawtooth?

Insert the W5 jumper cap into the ADJ DUTY position. Connect the oscilloscope to OUT1 or OUT. Press the S1 button to switch the waveform (triangle wave) output. Adjust the DUTY adjustable resistor to output the sawtooth wave.
