OWON PDS5022T (01) PDF Document

Follow these steps for a fast function check of the OWON PDS5022T:

1. Connect the instrument to power and push the power switch button.

2. When the prompt to press any key appears, press the UTILITY button, then press the menu selection button F2 to recall the factory settings.

3. Set the switch on the probe to 10X and connect it to the CH1 channel by aligning the slot and rotating the connector to the right.

4. Connect the probe tip and ground clamp to the probe compensator connector.

5. Press the AUTO SET button. A square wave of 1 KHz frequency and 5V peak-to-peak value should be displayed within several seconds. Repeat this process for CH2.

When connecting a probe for the first time, perform this adjustment to match the probe with the input channel of the OWON PDS5022T:

1. Set the attenuation coefficient in the menu to 10X and the switch on the probe to 10X. Connect the probe to the CH1 channel.

2. Connect the probe tip to the signal connector of the probe compensator and the reference wire clamp to the ground wire connector.

3. Press the AUTOSET button.

4. Check the displayed waveform. If the waveform is not compensated correctly, regulate the probe until a correct compensation is achieved.

To set the probe attenuation coefficient for the OWON PDS5022T, press the function menu button for the channel you are using, then push the menu selection button corresponding to the probe until the correct value is shown.

Note: Ensure the attenuation switch on the physical probe matches the menu selection on the OWON PDS5022T. When the probe switch is set to 1X, the bandwidth is limited to 5MHz.

The self-calibration procedure allows the OWON PDS5022T to reach optimum condition. It must be executed if the ambient temperature varies by 5 degrees Celsius or more.

1. Disconnect all probes and wires from the input connectors.

2. Press the UTILITY button to call out the FUNCTION menu.

3. Push the F3 menu selection button to choose Perform Self-Calibration.

4. Run the program after confirming that everything is ready.

Ensure no contacts are made to any input channels until the calibration is done.

The OWON PDS5022T supports additive and subtraction operations between Channel 1 and Channel 2, as well as FFT operations.

1. Press the MATH MENU button to call out the WAVE MATH menu.

2. Press the F3 menu selection button to choose the desired operation, such as CH1+CH2. The calculated waveform M will be displayed.

The available calculations are:

Setting	Description
CH1-CH2	Subtract the Channel 2 waveform from the Channel 1 waveform.
CH2-CH1	Subtract the Channel 1 waveform from the Channel 2 waveform.
CH1+CH2	Add the Channel 1 waveform to the Channel 2 waveform.
FFT	Waveform of corresponding FFT operation.

To perform an FFT operation on the OWON PDS5022T:

1. Press the MATH MENU button and select FFT.

2. Press F1 to turn the FFT function on or off.

3. Use F2 to switch the source between CH1 and CH2.

4. Use F3 to select the FFT window type (Rectangle, Hamming, Hanning, or Blackman).

5. Use F4 to switch the display format between dB and Vrms.

6. Use F5 to zoom in or out using multipliers *1, *2, *5, or *10.

The OWON PDS5022T can save up to four waveforms.

To save a waveform:

1. Under the WAVE SAVE MENU, press F1 to select the source (CH1, CH2, or MATH).

2. Press F2 to assign a location (A, B, C, or D).

3. Press F3 to save the waveform.

To recall a waveform:

1. Activate the WAVE SAVE menu.

2. Press F2 to select the desired location (A, B, C, or D).

3. Press F4 to set CH(X) to ON. The stored waveform will be displayed on the screen.

If you have acquired a signal but it is not displayed on the screen of the OWON PDS5022T, check the following:

1. Check whether the probe is properly connected to the signal connecting wire.

2. Check whether the signal connecting wire is correctly connected to the BNC channel connector.

3. Check whether the probe is properly connected to the object being measured.

4. Check whether there is any signal generated from the object being measured by testing the connection with another channel.

5. Re-run the signal acquisition operation.

If the waveform on the OWON PDS5022T is displayed but not stable, check the following:

1. Verify that the Source item in the TRIG MODE menu matches the signal channel being used.

2. Verify the trigger Type. For common signals, choose Edge trigger mode; for video signals, choose Video. The waveform can only be displayed steadily if the proper trigger mode is applied.

3. Attempt to change the trigger coupling to high frequency suppression or low frequency suppression to smooth out noise triggered by interference.

To charge the lithium battery of the OWON PDS5022T:

1. Charge the battery for 12 hours while the oscilloscope is turned on to ensure a full charge.

2. A fully charged battery can supply power for up to 4 hours.

3. Battery power indication symbols will appear on the top of the panel when the OWON PDS5022T is powered by the battery.

Note: Avoid overheating the battery during charging by ensuring the environment temperature does not exceed the specifications.
