After receiving your HANTEK HRDO4054D, please perform the following initial checks:

1. Check the shipping package: Inspect for any damage caused by transportation. If the packaging cartons or protective foam are seriously damaged, keep them until the entire machine and accessories have passed electrical and mechanical testing.

2. Check the accessories: Verify that all accessories listed in Appendix A of the user manual are present and undamaged. If anything is missing or damaged, contact your dealer.

3. Check the machine: If you find that the instrument is damaged, not working properly, or fails its performance test, contact the dealer responsible for the business.

Function Inspection:

1. Click on [Default Setup] in the button area to restore the oscilloscope to its factory settings.

2. Connect the grounding crocodile clamp of the probe to the grounding terminal.

3. Connect the probe to the input terminal of channel 1 and the compensation signal output terminal.

4. Set the probe attenuation ratio to X10 and click on [Auto Scale].

5. Observe the waveform to see if a square wave signal is displayed normally. Check other channels using the same method.

Probe Compensation:

If the square wave waveform is not displayed correctly during the function check, you need to compensate the probe. This adjustment is required the first time you connect a probe to any input channel.

1. Perform the first four steps of the “Function Inspection” as described above.

2. Use a non-metallic screwdriver to adjust the variable capacitance on the probe until the waveform displayed on the screen is “Perfectly compensated” (a clean square wave). Uncompensated or offset probes can lead to measurement errors.

The front panel of the HANTEK HRDO4054D includes a touch screen, various keys, and knobs for controlling its functions.

The HANTEK HRDO4054D features a 10.1-inch capacitive touch screen that supports multi-touch and gesture operations. The main controls are:

1. Tap: Tap a menu or function on the screen with one finger to operate menus, use the pop-up numeric keyboard, set file names with the virtual keyboard, or close pop-up boxes.

2. Drag: After holding down a target, drag it to the desired position. This can be used to drag a waveform to change its displacement/offset or drag a window to change its position.

3. Pinch & Stretch: Bring two fingers together or apart on the screen. This gesture can amplify or reduce the waveform. Vertical pinching adjusts the vertical scale (V/div), and horizontal pinching adjusts the horizontal time base (s/div).

4. Rectangle Drawing: Click on the Hantek logo, then click on AreaSel to switch to rectangular drawing mode. Drag your finger on the screen to draw a rectangle. A menu will appear allowing you to select functions like “Histogram,” “Enlarge Level,” “Enlarge Vertical,” or “Enlarge Waveform” for the selected area.

The help system on your HANTEK HRDO4054D provides instructions for various function buttons and their corresponding menu keys. To use it:

1. Click the [Help] button in the button area to enter the help module.

2. Press any other key to get help information for that specific key.

3. Press the [Help] button again to exit the help module.

For example, after clicking [Help], if you then click the [QuickAction] button, an explanation menu for [QuickAction] will pop up on the screen.

The vertical system on the HANTEK HRDO4054D has several adjustable settings for each channel:

Enable/Disable Channel: Press the channel button (e.g., [CH1]) or tap the channel status label at the bottom of the screen to turn the channel on or off.

Adjust Vertical Scale (V/div): Rotate the vertical scale knob for the selected channel to increase or decrease the waveform amplitude on the screen. Clockwise decreases the V/div value (zoom in), and counter-clockwise increases it (zoom out).

Adjust Vertical Offset: Rotate the vertical offset knob to move the waveform up or down on the screen. Press the knob to reset the offset to zero.

Channel Coupling: Open the channel menu and select Coupling. You can choose DC (passes both AC and DC components), AC (blocks DC component), or GND (disconnects the input signal to display a zero-volt reference).

Bandwidth Limit: In the channel menu, select BW Limit to reduce high-frequency noise. You can set it to 20M, 100M, 200M, 350M, or turn it off.

Probe Ratio (Attenuation): In the channel menu, select Attenuation and set the value to match the probe you are using (e.g., 1X, 10X) to ensure correct voltage readings.

Input Impedance: Select Impedance in the channel menu to switch between 1M Ω (high impedance) and 50 Ω (for matching with 50 Ω sources).

Waveform Invert: Turn the Invert function on or off in the channel menu to vertically flip the waveform.

You can control the horizontal view of the waveform on your HANTEK HRDO4054D using the following settings:

1. Adjust Horizontal Time Base (s/div): Rotate the horizontal time base knob (the larger knob in the Horizontal section) to change the time scale. Turning it clockwise decreases the time per division (zooms in horizontally), and turning it counter-clockwise increases the time per division (zooms out horizontally).

2. Adjust Horizontal Position: Rotate the horizontal position knob (the smaller knob) to move the waveform left or right on the screen. This changes the position of the trigger point relative to the center of the screen. Press the knob to reset the horizontal position to zero.

3. Delayed Sweep (Zoom): Press the [Zoom] button to activate the delayed sweep function. This splits the screen into two display areas. The top half shows the main time base, and the bottom half shows a horizontally expanded (zoomed-in) view of a section of the waveform. You can use the horizontal knobs to adjust the zoomed area and its magnification.

The HANTEK HRDO4054D offers several acquisition modes, which you can select by pressing the [Acquire] key:

Normal: This is the default mode. The oscilloscope samples the signal at equal time intervals to reconstruct the waveform. It provides the best display for most waveforms.

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

Peak: In this mode, the oscilloscope captures the maximum and minimum values of the signal within each sampling interval. This is useful for capturing high-frequency glitches and avoiding aliasing.

High Resolution: This mode uses a supersampling technique to average adjacent points from a single acquisition. It reduces random noise and produces a smoother waveform, especially when the sampling rate is much higher than the storage rate.

Setting the trigger correctly is crucial for obtaining a stable waveform. You can access the trigger menu by pressing the [Trig Menu] button. Here are the basic trigger settings:

Trigger Type: Select the type of event you want to trigger on. Common types include Edge, Pulse, Video, Slope, etc. The default is Edge trigger.

Trigger Source: Choose the signal source for the trigger. This can be any of the analog channels (CH1-CH4), the external trigger input (EXT), or digital channels.

Trigger Level: Use the Trigger knob to set the voltage level that the signal must cross to cause a trigger. The trigger level is indicated by a horizontal line on the screen.

Trigger Mode:

Auto: The oscilloscope will trigger when the trigger condition is met, but will also generate untriggered sweeps if no trigger occurs, ensuring a waveform is always visible.

Normal: The oscilloscope only updates the display when a valid trigger event occurs. If no trigger occurs, the display will not update.

Single: The oscilloscope acquires one waveform when a trigger event occurs and then stops.

Trigger Holdoff: Set a period of time after a trigger during which the oscilloscope will ignore subsequent trigger events. This is useful for stabilizing the display of complex or periodic signals that have multiple valid trigger points within one cycle.

The HANTEK HRDO4054D can perform mathematical operations on waveforms. Press the [Math] button to access the Math menu.

Arithmetic Operations: Perform point-by-point addition (A+B), subtraction (A-B), multiplication (A*B), and division (A/B) on signals from two sources (Source A and Source B).

FFT (Fast Fourier Transform): Calculate and display the frequency spectrum of a source channel. You can adjust the frequency range (Span/Center or Start/End), vertical scale, and select a windowing function to reduce spectral leakage. Available window functions include Rectangular, Hanning, Hamming, and Blackman-Harris.

Logic Operation: Perform logical operations such as AND (A&&B), OR (A||B), XOR (A^B), and NOT (!A) on source channels. The logic level is determined by comparing the signal voltage to a set threshold for each channel.

Function Operation: Apply functions to a single source waveform, including Integral (Intg), Differentiate (Diff), Square Root (Sqrt), Logarithm (Lg, Ln), Exponent (Exp), and Absolute Value (Abs).

Digital Filtering: Apply LowPass, HighPass, BandPass, or BandStop filters to a source waveform.

Expression: Create complex mathematical expressions by combining multiple operators and sources.

The HANTEK HRDO4054D can automatically measure a wide range of waveform parameters. Press the [Meas] button to enter the measurement menu.

1. Add a Measurement: In the Meas menu, select “Add”.

2. Select Category: Choose a measurement category: Horizontal (time-related), Vertical (voltage-related), or Other (delay, phase, area).

3. Select Parameter: Tap the specific parameter you want to measure (e.g., Freq, Period, VMax, PkPk).

4. Select Source: Choose the source channel (CH1-CH4, Math, etc.) for the measurement.

The measurement results will be displayed at the bottom of the screen. You can display multiple measurements simultaneously.

All Measure: To display all available parameters for a specific channel at once, press [Meas] -> All Measure and select the desired channel.

Statistics: You can turn on statistics to view the current, mean, max, min, standard deviation, and count for each active measurement.

Cursors are markers you can move on the screen to take manual measurements. Press the [Cursors] button to open the cursor menu.

1. Select Mode: Choose the cursor mode. The default is None (off). Select Manual or Tracking.

2. Select Type: Choose the cursor type. ‘X’ cursors are vertical lines for measuring time and frequency. ‘Y’ cursors are horizontal lines for measuring voltage.

3. Select Source: Choose the waveform you want to measure.

4. Adjust Cursors: A cursor measurement window will appear. Use the multi-function knob (V0) to adjust the positions of Cursor A and Cursor B. You can adjust them individually (AX, BX, AY, BY) or together (AXBX, AYBY).

The cursor window displays the absolute position of each cursor (AX, AY, BX, BY) and the difference between them (BX-AX for time, BY-AY for voltage). For X cursors, it also shows the reciprocal of the time difference (|1/dX|), which is the frequency.

In Tracking mode, the cursors automatically “stick” to the selected waveform, making it easier to measure points on the trace.

The Search and Navigation functions help you find specific events within a captured waveform.

Search Function:

1. Press the [Search] button on the front panel.

2. In the Search menu, turn the function on.

3. Select the search ‘Type’, which can be Edge, Slope, Runt, Pulse, UART, I2C, or SPI.

4. Configure the settings for the chosen search type (e.g., for Edge search, set the threshold).

The oscilloscope will automatically find and mark all events in the waveform that match your criteria. The found events are displayed in a Mark Table.

Navigation Function:

The navigation keys in the Horizontal control area can be used to navigate through different types of data:

Event Navigation: After performing a search, use the left and right arrow keys in the Navigate section to jump to the previous or next marked event in the Mark Table.

Time Navigation: When data collection is stopped, use the navigation keys to play the captured data waveform left or right, or to stop playback. Pressing the keys multiple times can accelerate the playback speed.

Recording & Playing Navigation: After recording a waveform, use the navigation keys to play the recorded frames in forward or reverse sequence, or to stop playback.

You can save and load various types of data to the oscilloscope’s internal memory or an external USB flash drive. Press the [Save/Recall] button to access the menu.

Storage Type (Saving):

Save Image: Captures a screenshot of the display. You can choose the format (*.png, *.bmp, *.jpg, *.tif), file name, and whether to save in color or grayscale.

The HANTEK HRDO4054D can decode several common serial protocols. To access the function, press the [Decode] button.

General Decoding Procedure (Example for UART):

1. Press [Decode].

2. Bus Type: Select “UART” from the pop-up menu.

3. Bus Status: Turn the bus decoding On.

4. Source: Enter the Source Settings menu.

Tx/Rx Source: Assign the appropriate oscilloscope channels (e.g., CH1 for Tx, CH2 for Rx).

Threshold: Set the voltage threshold for determining a logical high or low.

5. Baud: Select the correct baud rate for the signal.

6. Setting: Enter the Settings menu to configure protocol-specific parameters like Data Bits, Parity, Stop Bit, and Endian (bit order).

7. Display: Configure how the decoded data is displayed, including the Format (Hex, Dec, Bin, ASCII) and whether to show an Event Table.

The decoded data will be overlaid on the waveform on the screen. The procedure for other protocols like I2C, SPI, CAN, and LIN is similar but requires setting protocol-specific parameters such as clock/data channels (for I2C/SPI) and signal type.

If the waveform display on your HANTEK HRDO4054D appears stepped or ladder-like, you can try the following:

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

2. Check the display type. If it is set to “Vector”, the lines drawn between the sample points may cause this effect. While this is normal for some signals at certain time bases, adjusting the horizontal scale is the primary solution.

If you are not seeing a waveform on your HANTEK HRDO4054D, follow these troubleshooting steps:

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

2. Ensure that the channel you are using is turned on (press the corresponding CH1-CH4 button).

3. Verify that there is a signal being output from the device you are testing.

4. If it is a DC signal with a large amplitude, you may be off-screen. Try adjusting the vertical scale (V/div) or vertical position.

5. Press the [Auto Scale] button. This function automatically adjusts the vertical, horizontal, and trigger settings to display a stable waveform for most common signals.

If the touch functions on your HANTEK HRDO4054D are not responding, try these steps:

1. Check if the touch screen function is locked. Press the [Touch Lock] key in the button area to enable or disable the touch screen function. The key will be lit when locked.

2. Inspect the screen and your fingers for any dirt, grease, or moisture. Clean the screen with a soft, dry cloth if necessary.

3. Check if the oscilloscope is near a strong magnetic field. If so, move the device away from the source of interference.

If your HANTEK HRDO4054D is not recognizing a connected USB flash drive, follow these steps:

1. First, check if the USB drive itself is functioning correctly by testing it in another device, like a computer.

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

3. Ensure the USB drive is formatted with the FAT32 file system. The oscilloscope may not recognize other formats like NTFS or exFAT.

4. Try restarting the oscilloscope and re-inserting the USB drive for inspection.
