Comprehensive Guide to ZOYI ZT-703S (Part 9): Introduction to Oscilloscope Functions – Trigger System

What is the Trigger System?

The trigger system in an oscilloscope is essential for stabilizing and capturing specific waveforms. It allows you to set conditions under which the oscilloscope will start recording data. Without a proper trigger, waveforms may appear jumbled or unstable, making it difficult to analyze the signal. The ZT-703S offers a robust trigger system that ensures you can capture the exact waveform you need for analysis.

Trigger Modes

The ZT-703S provides three primary trigger modes: Auto, Normal, e Single. Each mode serves a different purpose depending on the type of signal you’re working with.

1. Auto Mode: In this mode, the oscilloscope continuously refreshes the waveform in real-time, even if no trigger condition is met. This is useful for observing signals that are always present but may not have a consistent trigger point.
2. Normal Mode: This mode waits for a specific trigger condition to be met before capturing and displaying the waveform. Once the trigger condition is satisfied, the oscilloscope locks and holds the waveform on the screen. This is ideal for capturing intermittent or irregular signals.
3. Single Mode: As the name suggests, this mode captures a single waveform when the trigger condition is met. After capturing the waveform, the oscilloscope stops further acquisition. This is useful for capturing one-time events or transient signals.

Trigger Edge and Source

The ZT-703S allows you to set the trigger edge to either rising or falling. This determines whether the oscilloscope triggers on the upward or downward slope of the signal. You can also select the trigger source, choosing between CH1 or CH2, depending on which channel you’re monitoring.

Trigger Level and Position

The trigger level is the voltage threshold at which the oscilloscope will trigger. You can adjust this level using the up and down arrow keys, and the trigger position can be set to the 50% midpoint of the waveform for balanced triggering.

Horizontal and Vertical Trigger Cursors

The ZT-703S also features horizontal and vertical trigger cursors, which allow you to fine-tune the trigger point both in time and voltage. This is particularly useful when you need to capture a specific segment of a waveform or measure the exact voltage at a particular point in time.

Applicazioni pratiche

The trigger system is invaluable in various applications, from debugging electronic circuits to analyzing communication signals. For instance, if you’re working with a PWM (Pulse Width Modulation) signal, you can set the trigger to capture the rising edge of the pulse, ensuring that you get a stable and consistent waveform for analysis.

Conclusione

The trigger system in the ZOYI ZT-703S is a powerful tool that enhances your ability to capture and analyze waveforms accurately. Whether you’re dealing with continuous signals, intermittent pulses, or one-time events, the ZT-703S provides the flexibility and precision you need.
