• Using the Knob: Rotate the horizontal time base knob in the “Horizontal” control area. Rotating clockwise decreases the time per division (zooms in), and counterclockwise increases it (zooms out).

• Using the Touch Screen: Click on the horizontal time base label at the top of the screen to open a pop-up menu for direct entry or adjustment.

• Using Pinch Gesture: Use a horizontal pinch or stretch gesture on the waveform to adjust the time base.

Open the [Acquire] menu to access these settings.

Timebase Modes:

• YT Mode: This is the standard mode where the Y-axis represents voltage and the X-axis represents time. At time base settings of 100 ms/div or slower, the oscilloscope enters a scanning mode.

• XY Mode: Displays a Lissajous pattern where the X-axis and Y-axis both represent voltage levels from two different channels. This is useful for measuring phase differences between two signals of the same frequency.

• ROLL Mode: The waveform scrolls from right to left across the screen, which is useful for observing low-frequency signals. The horizontal gear range is 50ms to 1 ks.

Acquisition Modes:

• Normal: The oscilloscope samples the signal at equal time intervals to reconstruct the waveform. This is the best mode for most applications.

• Average: The oscilloscope averages multiple sampled waveforms to reduce random noise and improve vertical resolution. You can set the number of averages from 2 to 1024.

• Peak: The oscilloscope captures the maximum and minimum values of the signal within each sampling interval. This mode is useful for capturing glitches and avoiding aliasing.

• High Resolution: This mode averages adjacent points of a single sampled waveform to reduce random noise and produce a smoother display. It is used when the sampling rate is higher than the storage rate of the acquisition memory.

You can enter the trigger menu by pressing the [Trig Menu] button or clicking the trigger tab at the top of the screen. The main trigger settings are:

1. Trigger Type:

Press the [Trig Menu] button, then select the “Type” menu. The HANTEK HRDO4104C supports numerous trigger types, including Edge, Pulse, Video, Slope, Overtime, Window, Runt, Logic, Pattern, and various serial bus triggers (UART, I2C, SPI, CAN, LIN).

2. Trigger Source:

Select the signal source for the trigger. This can be any of the analog channels (CH1-CH4), the external trigger input (EXT), or any of the digital channels (if a logic probe is connected).

3. Trigger Mode:

This determines how the oscilloscope acquires data when a trigger condition occurs.

• Auto: The oscilloscope will sweep even without a trigger event, allowing you to see a signal. If a trigger event occurs, the display will become stable.

• Normal: The oscilloscope only acquires and updates the waveform when a valid trigger event is detected.

• Single: The oscilloscope waits for a single trigger event, captures one waveform, and then stops acquiring.

4. Trigger LEVEL:

Rotate the “Trigger” knob to adjust the voltage level that the trigger source signal must cross to cause a trigger. Pressing the knob sets the level to 50% of the waveform’s amplitude.

5. Trigger Holdoff:

Set a specific time period after a trigger during which the oscilloscope will not accept another trigger. This is useful for stabilizing the display of complex or periodic waveforms that have multiple valid trigger points within one cycle.

If the waveform appears as a series of steps or “ladder-like,” try the following:

1. The horizontal time base might be too slow for the signal being displayed, resulting in too few sample points per cycle. Try increasing the horizontal time base (i.e., decreasing the time/division value) to improve the display resolution.

2. If the display type is set to “Vector” in the [Display] menu, the oscilloscope draws straight lines between sample points. This can cause a ladder-like appearance on some waveforms. Changing the display mode might alter the appearance, but the primary solution is to adjust the time base.

If no signal waveform is displayed, follow these troubleshooting steps:

1. Check that the probe is correctly and securely connected to the BNC input connector of the signal channel.

2. Check if the channel you are using is enabled. Press the corresponding channel button (e.g., [CH1]) to ensure it is turned on.

3. Verify that the circuit or device you are testing is actually outputting a signal.

4. If it is a DC signal with a large amplitude, you may need to increase the vertical scale (V/div) to bring the signal into view.

5. Press the [Auto Scale] button. This function will automatically detect the signal and adjust the oscilloscope settings to display it.

If you still see no waveform, please contact technical support.

If the touch screen functions cannot be used normally, please check the following:

1. Check if the touch screen function has been disabled. If the [Touch Lock] button in the front panel button area is illuminated, the touch function is locked. Press it to turn off the lock and enable the touch screen.

2. Check for any dirt or debris on the screen or on your fingers. If there is, please clean it first.

3. Check if the oscilloscope is close to a strong magnetic field. Strong magnetic interference can affect touch screen performance. If it is, please move the oscilloscope away from the source of interference.

If you still cannot use the touch screen, please contact Hantek technical support.

If the oscilloscope cannot recognize your USB storage device, try these steps:

1. Check if the USB drive is functioning properly by testing it on another device.

2. Confirm the capacity of the USB flash drive. It is recommended to use a USB flash drive that does not exceed 16GB for this oscilloscope.

3. Confirm that the format of the USB drive is FAT32.

4. Restart the oscilloscope and reinsert the USB drive for inspection.

If you still cannot use the USB drive, please contact Hantek Technical Support.
