To Enable an Analog Channel (e.g., CH1):

There are two ways to enable a channel:

1. Click on the channel status label at the bottom of the screen. The label will light up, and the corresponding button in the button area [CH1] will also light up.

2. Press the [CH1] button directly on the front panel. The light on the button and the corresponding channel knob will light up.

To Disable an Analog Channel:

1. If the CH1 channel is already open and currently selected, press the [CH1] button once to close it.

2. If CH1 is open but not selected, press [CH1] once to select it, then press it again to close it.

3. Use the touch screen to click on the channel number on the channel menu at the bottom of the screen to close it.

To Adjust the Vertical Scale (V/div):

The vertical scale adjusts the voltage value represented by each grid. To adjust it for a channel (e.g., CH1):

1. Rotate the vertical gear knob corresponding to CH1. Rotate clockwise to decrease the V/div value (zoom in vertically) and counter-clockwise to increase it (zoom out vertically).

2. Use the touch screen function. Click on the CH1 channel menu at the bottom of the screen, and in the pop-up menu, set the vertical gear.

To Adjust the Vertical Offset:

The vertical offset adjusts the vertical position of the waveform relative to the center of the screen.

1. Rotate the vertical offset knob in the button area to move the waveform up or down. Pressing this knob resets the offset to zero.

2. Use the touch screen function. Drag the waveform up or down with your finger.

3. Click on the CH1 channel menu at the bottom of the screen, and in the pop-up menu, set the offset.

Channel Coupling:

Open the vertical menu for the desired channel and click on the Coupling menu to select the method.

DC: Allows both DC and AC components of the signal to pass through.

AC: Blocks the DC component of the signal.

GND: Disconnects the input signal and grounds the channel input.

Bandwidth Limit:

This function reduces noise in the displayed waveform. Click to open the channel menu, then click on the BW Limit menu. You can choose to set the limit to 20M, 100M, 200M, 350M, or turn it off.

Input Impedance:

Open the channel menu and click the Impedance menu tab. Select an input impedance of 1M Ω or 50 Ω.

1M Ω: High impedance setting, suitable for general purpose measurements where minimal circuit loading is desired.

50 Ω: Matches the oscilloscope with a device that has a 50 Ω output impedance.

Open the [Acquire] menu and click on the Acquisition method menu to select one of the following modes:

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

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 collects the maximum and minimum values of the signal within each sampling interval. This is useful for obtaining the envelope of a signal or capturing narrow pulses that might otherwise be missed (glitch capture).

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

Here are some common issues and their solutions for the HANTEK HRDO4054C:

The display of the waveform is ladder-like.

1. The horizontal time base might be too slow. Increase the horizontal time base to improve the display.

2. If the display type is set to “Vector,” the lines between sample points can cause this effect.

After connecting the power cord, the button light does not light up.

1. Check if the power switch of the oscilloscope is turned on.

2. Check if the fuse is intact. If it needs replacement, use a fuse that meets the product’s specifications.

No waveform of the signal is displayed on the screen.

1. Check if the probe is correctly connected to the BNC connector of the input channel.

2. Check if the channel is enabled (using the CH1-CH4 menu buttons).

3. Check if the signal source is outputting a signal.

4. If it is a DC signal with a large amplitude, you may need to increase the amplitude range (V/div).

5. Press the automatic measurement button [Auto Scale] to automatically detect the signal.

The touch functions cannot be used normally.

1. Check if the touch screen function is enabled. If not, click the [Touch Lock] button to turn it on.
