The horizontal system controls the time axis of the waveforms. Here’s how to adjust its settings:

To Adjust the Horizontal Time Base (s/div):

The horizontal time base represents the time value per horizontal grid division.

• Use the horizontal time base knob (marked with a wave and arrows) to adjust the time base. Rotate clockwise to decrease the time base (zoom in) and counterclockwise to increase it (zoom out).

• Use a pinch/stretch gesture on the touch screen to adjust the time base.

• Tap the horizontal time base label at the top of the screen to open a pop-up menu for direct value entry.

To Adjust the Horizontal Position:

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

• Rotate the horizontal position knob to move all waveforms left or right. Press the knob to reset the position to zero.

• Drag the waveform horizontally on the touch screen.

Delayed Sweep (Zoom):

This function horizontally amplifies a section of the waveform for detailed viewing.

• Press the [Zoom] button in the horizontal control area. The screen will split into two display areas.

• The top half shows the original waveform (main time base).

• The bottom half shows the horizontally expanded waveform (delayed scanning time base).

• Use the horizontal time base knob to change the zoom factor and the horizontal position knob to move the zoomed window across the original waveform.

Press the [Acquire] key to enter the sampling settings menu. Here you can configure the following:

1. Timebase Mode:

• YT Mode: The standard mode where the Y-axis is voltage and the X-axis is time.

• XY Mode: Displays a Lissajous pattern where the X-axis and Y-axis both represent voltage levels, useful for measuring phase differences.

• ROLL Mode: For slow signals, the waveform scrolls from right to left across the screen. This mode is available for time base settings of 50ms/div and slower.

2. Acquisition Mode:

• Normal: Samples the signal at equal time intervals. This provides the best display for most waveforms.

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

• Peak: Captures the maximum and minimum values within each sampling interval to display the signal envelope and avoid aliasing on narrow pulses.

• High Resolution: Averages adjacent points from a single acquisition to reduce noise and produce a smoother waveform.

3. Memory Depth:

This is the number of waveform points stored in a single acquisition. A higher memory depth allows for a higher sample rate at longer time base settings. You can select from various options depending on whether you are in single, dual, or full channel mode (e.g., Auto, 25K, 250K, 2.5M, up to 1G).

4. Horizontal Expansion:

Determines the reference point for horizontal expansion/compression. Options include expanding from the center, left, right, or trigger point of the screen.

5. Segmented Acquisition:

Allows the capture and storage of multiple trigger events into segments, ignoring the dead time between events.

Setting a trigger correctly is essential for a stable waveform display. You can enter the trigger menu by pressing the [Trig Menu] button or tapping the trigger status area at the top of the screen.

1. Set Trigger Type:

In the [Trig Menu], select Type. The HANTEK HRDO4054E offers numerous trigger types, including:

• Edge: Triggers on a rising, falling, or either edge of the signal.

• Pulse: Triggers on pulses of a specified width (positive or negative).

• Video: Triggers on standard analog video signals (NTSC, PAL/SECAM).

• Slope: Triggers on the slew rate (positive or negative slope time) of the signal.

• Other advanced types like Runt, Window, Logic, Delay, Setup/Hold, and serial bus triggers (UART, I2C, SPI, CAN, LIN).

2. Set Trigger Source:

Select the Source menu to choose the input for the trigger circuit. Options include any analog channel (CH1-CH4), an external trigger signal ([EXT In]), or digital channels (D0-D15).

3. Set Trigger Level:

Rotate the Trigger knob to move the trigger level line up or down on the display. The trigger occurs when the source signal crosses this voltage level. Press the knob to set the level to 50% of the waveform’s peak value.

4. Set Trigger Mode:

• Auto: The oscilloscope acquires a waveform even without a valid trigger. If no trigger occurs, it will auto-trigger after a certain time, which may result in an unsynchronized display.

• Normal: The oscilloscope only acquires and updates the display when a valid trigger event occurs. If no trigger occurs, the display remains unchanged.

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

5. Set Trigger Holdoff:

In the [Trig Menu], adjust the Holdoff time. This sets a period after a trigger during which the oscilloscope will not accept another trigger, which is useful for stabilizing complex, repetitive waveforms like pulse trains.

Press the [Math] button to access the mathematical operations menu. The HANTEK HRDO4054E supports several types of operations:

• Arithmetic Operations: Perform point-by-point math between two sources (A and B). Includes Addition (A+B), Subtraction (A-B), Multiplication (A*B), and Division (A/B).

• FFT (Fast Fourier Transform): Calculates and displays the frequency spectrum of a source waveform. You can configure the source, frequency range (span/center or start/end), vertical units (dBm/dBV or Vrms), and use different windowing functions.

• Logic Operations: Perform logical operations on waveforms based on a set threshold. Includes AND (A&&B), OR (A||B), XOR (A^B), and NOT (!A).

• Function Operations: Apply a mathematical function to a single source waveform. Functions include Intg (integral), Diff (differential), Sqrt (square root), Lg (base 10 logarithm), Ln (natural logarithm), Exp (exponent), and Abs (absolute value).

• Digital Filtering: Apply a digital filter to a source waveform. Filter types include LowPass, HighPass, BandPass, and BandStop.

• Expression: Allows you to create and edit complex mathematical expressions by combining multiple operators and sources.

• Adjust: Use the multifunction knob V0 to position cursors A and B. The measurement window will display the values at each cursor (AX, AY, BX, BY) and the difference between them (ΔX, ΔY).

The HANTEK HRDO4054E can decode several common serial protocols. To begin, press the [Decode] button on the front panel.

General Setup Steps:

1. Select Bus Type: In the decode menu, press Bus Type and select the protocol you want to decode (e.g., UART, I2C, SPI, CAN, LIN).

2. Enable Bus Status: Press Bus Status to turn the decoder ON.

3. Configure Source(s): Press Source to enter the source settings menu. Here you will assign the physical channels (CH1-CH4, D0-D15) to the protocol’s signal lines (e.g., for UART: Tx and Rx; for I2C: SCL and SDA).

4. Set Thresholds: For each assigned channel, set the logic threshold voltage. When adjusting, a dashed line will appear on the screen to indicate the level.

5. Configure Protocol Parameters: Go to the Setting menu to define protocol-specific parameters. This is a critical step.

• For UART: Set Baud rate, Data bits, Parity, Stop bits, and Endian (bit order).

• For I2C: The R/W bit can be included or not.

• For SPI: Set Timeout, Clock Edge (Slope), Endian, and Bus Width.

• For LIN: Set Baud Rate, Parity, and protocol Version.

• For CAN: Define the Signal type (CAN_H, CAN_L, etc.), Baud rate, and Sample Position.

6. Configure Display: In the Display menu, you can set the format of the decoded data (Hex, Dec, Bin, ASCII), the on-screen position of the decode bus, and open an Event Table for a detailed, chronological view of the decoded data packets.

Once configured, the decoded data will be overlaid on the waveform, showing values, packets, and errors in real-time.

The built-in Arbitrary Waveform Generator (AWG) can be accessed by pressing the [G1] or [G2] button in the “Wave Gen” section of the front panel.

To Output Basic Waveforms:

1. Press [G1] to open the signal generator settings for channel 1.

2. Click the Wave menu tab and select a basic waveform: Sine, Square, Ramp, Pulse, DC, Noise, Sinc, Exp.Rise, Exp.Fall, ECG, Gauss, Lorentz, or Haversine.

3. Adjust the waveform parameters:

• Frequency: Set the frequency of the waveform.

• Amplitude: Set the peak-to-peak voltage.

• Offset: Set the DC offset voltage.

• Start Phase: Set the starting phase of the waveform (0° to 360°).

• Other parameters: Depending on the waveform, you can also set Duty Cycle (for Square), Symmetry (for Ramp), or Pulse Width/Rise Time/Fall Time (for Pulse).

4. Impedance: Select the output impedance (HighZ or 50Ω).

To Output an Arbitrary Waveform:

1. In the Wave menu, select Arb.

2. You can then choose to:

• Load from CH: Load a waveform currently captured on one of the oscilloscope channels (CH1-CH4).

• Load Stored: Load an arbitrary waveform file (*.arb) from internal or external memory.

• Create/Edit: Use the built-in editor to create a new arbitrary waveform point by point.

Modulation and Burst:

In the generator settings, go to More -> Setting -> Type to select advanced functions:

• Modulation: Apply AM, FM, or PM to a carrier wave. You can configure the modulating waveform, frequency, and depth/deviation.

• Burst: Output a specified number of waveform cycles (N Cycle) or a continuous wave (Infinite) upon receiving a trigger. The trigger source can be internal (timed) or manual.

A ladder-like waveform display can be caused by two main factors:

1. The horizontal time base might be set too slow for the signal being viewed. Try increasing the horizontal time base (i.e., decreasing the s/div value) to see if it improves the display.

2. If the display type is set to “Vector”, the lines drawn between sample points can sometimes create a ladder-like effect, especially with a low sampling rate relative to the signal frequency. Check the display settings.

If you have a signal connected but no waveform is displayed, follow these troubleshooting steps:

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

2. Ensure the channel you are using is turned on. You can check this by looking at the channel menu buttons (CH1-CH4) or the on-screen channel indicators.

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

4. If you are measuring a DC signal with a large amplitude, you may be off-screen. Try increasing the vertical scale (V/div) or adjusting the vertical offset.

5. Press the [Auto Scale] button. This will cause the oscilloscope to automatically adjust the vertical, horizontal, and trigger settings to find and display the signal.

If the touch screen is not responding, check the following:

1. Make sure the touch screen function is not locked. Press the [Touch Lock] key in the button area to enable or disable the touch function. The key will be lit when the touch screen is locked.

2. Check for any dirt, dust, or moisture on the screen or your fingers, and clean if necessary.

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

Pressing the [Default Setup] button restores the oscilloscope to a known starting state. The default settings are as follows:
