Comprehensive Guide to ZOYI ZT-703S (Part 18): Introduction to Oscilloscope Functions – Signal Generator Mode Signal Output

Welcome back to our comprehensive guide on the ZOYI ZT-703S, the versatile handheld oscilloscope that combines the functionalities of an oscilloscope, multimeter, and signal generator. In this installment, we’ll dive into the Signal Generator Mode Signal Output, a powerful feature that allows you to generate various waveforms for testing and troubleshooting electronic circuits.

Accessing the Signal Generator Mode

To access the Signal Generator Mode, navigate to the sixth page menu and press the F1 key.

This will bring up the extended applications menu, where you can select Signal Output.

Once selected, press the MENU key to enter the signal generator output settings interface.

Setting the Output Waveform

The ZT-703S allows you to generate several types of waveforms, including sine wave, square wave, triangle wave, half-wave, full-wave, and sawtooth wave. Here’s how you can set up the output waveform:

1. Selecting the Waveform Type:

Use the up and down arrow keys to cycle through the available waveform options. The screen will display the selected waveform in real-time, allowing you to visualize the output before connecting it to your circuit.

2. Adjusting Frequency:

Use the left and right arrow keys to switch between frequency units (1Hz and 1KHz).

Press the F1 key to increase the frequency setting and the F2 key to decrease it. For fine adjustments, short presses will increment or decrement the frequency by single units, while long presses will continuously change the frequency.

3. Setting Duty Cycle:

If you’re working with pulse or square waves, you can adjust the duty cycle using the F3 key to increase and the F4 key to decrease the duty cycle. Similar to frequency adjustment, short presses change the duty cycle by single units, while long presses allow for continuous adjustment.

4. Enabling/Disabling Output:

Press the MENU key to toggle the ON/OFF switch located at the top right corner of the screen. This allows you to enable or disable the signal output as needed.

Practical Applications

The Signal Generator Mode is incredibly useful for a variety of applications, such as:

• Testing Circuit Responses

Generate a known signal and observe how your circuit responds. This is particularly useful for testing filters, amplifiers, and other signal-processing circuits.

• Calibration

Use the signal generator to calibrate other instruments or to verify the accuracy of your measurements.

• Educational Purposes

The ability to generate different waveforms makes the ZT-703S an excellent tool for teaching and learning about electronic signals and circuit behavior.

Returning to Oscilloscope Mode

Once you’ve finished using the Signal Generator Mode, you can easily return to the oscilloscope interface by pressing the MODE key. This seamless transition between modes is one of the many features that make the ZT-703S a versatile and user-friendly tool.

Conclusion

The Signal Generator Mode on the ZOYI ZT-703S is a powerful feature that enhances the functionality of this already impressive handheld oscilloscope. Whether you’re testing circuits, calibrating equipment, or teaching electronics, the ability to generate precise waveforms on the fly is an invaluable tool.
