p>Waveform Invert: Toggles the inversion of the waveform display.

p>Amplitude Unit: Change the vertical unit to W, A, V, or U.

p>Fine tuning: Switch the vertical scale adjustment between coarse (standard 1-2-5 steps) and fine for more precise resolution.

p>Channel Delay: Set a delay time from -100ns to 100ns to correct for probe cable transmission delay (skew).

p>Offset Cal: Corrects for small DC offset deviations in the channel’s zero point.

p>Vertical Expansion: Choose whether changing the vertical gear expands/compresses the waveform around the screen center or around the GND (zero) level.

p>Channel Label: Set a custom label for the channel, which can be selected from a library or typed in manually.

To Adjust the Horizontal Position:

This adjusts the trigger point’s position relative to the center of the screen.

p>Rotate the horizontal position knob.

p>Click the horizontal displacement label at the top of the screen and use the pop-up menu.

Click the [Acquire] button to enter the sampling settings menu.

1. Timebase Mode:

p>YT Mode: Standard mode where the Y-axis is voltage and the X-axis is time.

p>XY Mode: Displays a Lissajous pattern, where the X-axis is the voltage of one channel and the Y-axis is the voltage of another. Useful for measuring phase differences.

p>ROLL Mode: For slow signals (50ms/div or slower), the waveform scrolls across the screen from right to left.

2. Acquisition Mode:

p>Normal: Standard sampling mode, best for most waveforms.

p>Average: Averages multiple waveform acquisitions to reduce random noise and improve vertical resolution.

p>Peak: Captures the maximum and minimum values in each sample interval to display the waveform envelope and avoid aliasing on narrow pulses.

p>High Resolution: Averages adjacent points within a single acquisition to reduce noise and create a smoother waveform.

3. Memory Depth:

Select the number of points to store in a single acquisition. A higher memory depth allows for a higher sample rate at longer time base settings. Options vary depending on whether one, two, or all four channels are active.

4. Horizontal Expansion:

Choose the reference point (Center, Left, Right, Trigger, User) around which the waveform expands or compresses when adjusting the time base.

Click the [Trig Menu] button or tap the trigger status area at the top of the screen to open the trigger menu.

1. Trigger Type: Select the type of trigger. The most common is Edge.

2. Trigger Source: Select the input source for the trigger (e.g., CH1, CH2, EXT, etc.). Choose the channel with the signal you want to stabilize.

3. Slope Type (for Edge Trigger): Choose whether to trigger on the Rising edge, Falling edge, or Either edge of the signal.

4. Trigger Level: Adjust the voltage level that the signal must cross to activate the trigger. Use the dedicated Trigger knob to move the trigger level line up and down on the display.

5. Trigger Mode:

p>Auto: The oscilloscope will sweep even without a valid trigger, allowing you to see a signal. It will lock to a stable waveform if a trigger is found.

p>Normal: The oscilloscope only updates the display when a valid trigger event occurs. If there is no trigger, the last acquired waveform remains on screen.

p>Single: The oscilloscope waits for one valid trigger event, captures the waveform, and then stops acquiring.

6. Trigger Holdoff: Set a time period during which the oscilloscope will ignore subsequent trigger events. This is useful for stabilizing complex waveforms like pulse trains where you want to trigger only on the first pulse.

The HANTEK HRDO4104D offers a variety of advanced trigger types:

p>Edge: Triggers on a rising, falling, or either edge crossing a specific voltage level.

p>Pulse: Triggers on positive or negative pulses that meet a specific width condition (e.g., greater than, less than, or equal to a set time).

p>Video: Triggers on standard analog video signals (NTSC, PAL/SECAM), allowing triggering on specific lines or fields.

p>Slope: Triggers on the rise or fall time of a signal edge, based on the time it takes to cross between two voltage levels.

p>Overtime: Triggers if the time interval between a rising and falling edge (or vice versa) is greater than a set timeout.

p>Window: Triggers when the input signal passes through either a high or low trigger level.

p>Runt: Triggers on pulses that cross one voltage level but fail to cross a second level.

p>Logic/Pattern: Triggers on a logical combination (AND, OR, NOT) of states (High, Low, Don’t Care) across multiple channels.

p>Delay: Triggers when the time between an edge on source A and an edge on source B meets a preset time condition.

p>Setup/Hold: Triggers on violations of setup and hold time between a clock and data signal.

p>Nth Edge: Triggers on the Nth edge of a burst after a specified idle time.

p>Serial Bus Triggers: UART, LIN, CAN, SPI, I2C. Triggers on specific protocol events like start of frame, specific data, address, or errors.
