DS1102E Digital Oscilloscope

Absolute error of my measurement

"Absolute measurement error" service allows you to estimate the measurement accuracy considering uncertainty (error) in the absolute value. It’s important if you take measurements at the range edge when the error value contributes to the value displayed on the device screen.

To get the value range it’d be enough to enter the estimate of the value under measurement into Value input field and to see the range of possible values taking all of the standardized errors into consideration.

Note: a point is used as a separator of the integer and fractional part.

RIGOL DS1102E digital oscilloscopes provide 20 types of wave parameters for automatically measuring, which contains 10 Voltage and 10 Time parameters.

In cursor mode, users can easily measure by moving cursor. Besides, 3 types of cursor measurement are optional: Manual, Track and Auto.

RIGOL DS1102E digital oscilloscope contains abundant triggers:

  • Edge trigger, Pulse Width trigger, Video trigger, Slope trigger
  • Alternate trigger

Especially the duration trigger is a new type from perfect combination of patten and pulse width trigger. Unique function of adjustable trigger sensitivity is good for filtering possible noise from signal in order to avoid false triggers.

In virtue of waveform recording function from RIGOL DS1102E digital oscilloscope, not only the outputs from two channels could be recorded, but also the waves outputted by Pass/Fail test could be easily recorded. Totally, up to 1000 frames of waves are available to record. Besides, users can analyze waves according to reall or save transient waves so as to get more exact datum.

The Pass/Fail function of RIGOL DS1102E digital oscilloscope monitors the changes of signals by comparing whether the input signal is within the pre-defined mask. The testing results not only can be displayed on screen or output by isolated pass/fail port, but also can be alarmed according to turn on system sound.

Capture the phase changes through a circuit

To view the input and output of the circuit in an X-Y display, do these steps:

  1. From the probe menu set the attenuation to 10X. Set the switch to 10X on the probes.
  2. Connect the CH 1 probe to the input of the circuit, and connect the CH 2 probe to the output.
  3. If the channels are not displayed, press the CH1 and CH2 buttons.
  4. Press the AUTO button.
  5. Adjust the vertical SCALE knob to display approximately the same amplitude on each channel.
  6. Press the MENU in horizontal control area to display the menu.
  7. Press the Time Base soft button to select X-Y. The oscilloscope displays a Lissajous pattern representing the input and output characteristics of the circuit.
  8. Adjust the vertical SCALE and POSITION knobs to a desirable waveform display.
  9. Apply the Ellipse method to observe the phase difference between the two channels.

Ellipse method to observe the phase difference

Sinθ = A/B or C/D, where θ = phase shift (in degrees) between the two signals. From the formula above, you could get:

θ = ±arcsine (A/B) or ±arcsine (C/D)

If the main axis of the ellipse is at I and III quadrant, θ must be in the range of (0~π/2) or (3π/2~2π). If the main axis is at II and IV quadrant, θ must be in the range of (π/2~π) or (π~3π/2).

Pass/Fail Test

When running test function the oscilloscope automatically examines the input signal, compared to the already built waveform mask. If the waveform "touches" the mask, a "Fail" occurs, otherwise the test passes. When needed, a programmable output can be used for external automatic control applications, such as the automatic failure product kick-out in a production line. The output is built in as a standard feature, and is optically isolated.

Do the following steps:

  1. Press Utility→Pass/Fail.
  2. Press Enable Test and select ON.
  3. Press Mask Setting→Load.
  4. Press Load to recall the saved mask or press X Mask and Y Mask to adjust the horizontal limit and vertical limit then press Create Mask to create a new mask.
  5. Press Output to select the expected outputting waveforms.
  6. Press Operate to start the test.

Frequently Asked Questions

  • The oscilloscope does not get a stable waveform display
  • After pressing the RUN/STOP button, the oscilloscope does not display any waveform
  • After the Acquisition is set to "Averages" or Display Persistence is set ON, the waveform refreshes slowly
  • The signal is displayed as ladder like waveform
  • High voltage measurement testing are not allowed over 300 volts
  • After the oscilloscope is powered on the display remains dark, what should I do?
  • When changing the horizontal sweep on the digital oscilloscope at different horizontal points observed inexplicable change in the form of the same signal, why is this happening?
  • The measured voltage amplitude value is 10 times greater or smaller than the actual value
  • There is wave form displayed, but it is not stable

  • The oscilloscope does not get a stable waveform display

    1. Check the Trigger Source and notice if it is set to the channel in use.
    2. Check the Trigger Type. Use "Edge" for normal signals, and use "Video" for VIDEO signals.
    3. Switch the coupling into HF Rejection or LF Rejection in order to filter the noise which disturbs trigger.
    4. Adjust the trigger Sensitivity and the hold off time.

    Up

    After pressing the RUN/STOP button, the oscilloscope does not display any waveform

    Check whether the Trigger Mode is set to "Normal" or "Single" and see whether the trigger level is out of the signal range. If yes, set the trigger level in proper range by turning the LEVEL knob or pressing the 50% button. Or set the Trigger Mode as "AUTO". Moreover, push AUTO button to display the waveform on screen.
    Up

    After the Acquisition is set to "Averages" or Display Persistence is set ON, the waveform refreshes slowly

    It is normal in these settings.
    Up

    The signal is displayed as ladder like waveform

    1. The time base setting maybe is too slow. Turn the horizontal SCALE knob to increase horizontal resolution.
    2. Maybe the display Type is set to "Vectors". Set it to "Dots" mode.

    Up

    High voltage measurement testing are not allowed over 300 volts

    Even when you can read in a probe 600V PK CAT I. The Aktakom, Owon or Rigol oscilloscopes does not support more than 300V RMS or 400V PK. For higher voltage please contact us to request a special device.


    Up

    After the oscilloscope is powered on the display remains dark, what should I do?

    Please implement the following fault treatment procedure.

    • Check whether the power cable is connected properly.
    • Ensure the power switch is turned on.
    • Restart the instrument after completing the checks above.
    • If the oscilloscope still can not work normally, please call for service.

    Up

    When changing the horizontal sweep on the digital oscilloscope at different horizontal points observed inexplicable change in the form of the same signal, why is this happening?

    In fact, this is not a problem.

    Just keep in mind that you're using a digital oscilloscope, which digitizes the signal with different sampling rates depending on the selected horizontal sweep, and then connects the digitized points with strait line while restoring the real shape of the signal.

    Your first screen shows that you are measuring voltage 50 Hz with the 10 ms / div sweep and a sampling frequency of 20 kHz Ks/s

    One signal period (20 ms), digitized in this mode, 20E-03 (sec) * 20E03 (1/sec) = 400 points. This is enough to properly restore and interpolate a sine wave of 50 Hz (i.e. in a period of 20 ms).

    Normal display, with a sweep 10 ms / div:

    Distortion of the same signal at 10 s / div sweep

    Your second screen is set to sweep 10 sec / div, and sample rate on a sweep turned to 20 samples per second (20 Sa / s). I.e. one signal period 20 ms had: 20E-03 (sec) * 20 (1/sec) = 0.4 points. That means that to restore (to interpolate the points) a sine wave with less than one point in time is impossible, so you get this mess (known as "aliasing" or a false frequency) formed by the beats of the measured frequency and sampling frequency.

    In order to correctly install a data collection in a digital oscilloscope one should follow a simple rule - the sampling rate must be at least 5-10 times higher than the frequency signal, in that case you will not have the issues that we just discussed.

    This applies to all digital oscilloscopes and in no way connected to any particular make or model of oscilloscope or its probes.


    Up

    The measured voltage amplitude value is 10 times greater or smaller than the actual value

    Check whether the channel attenuation coefficient and the attenuation coefficient of the probe used is match.
    Up

    There is wave form displayed, but it is not stable

    • Check whether the Source item in the TRIG MODE menu is in conformity with the signal channel used in the practical application.
    • Check on the trigger Type item: The common signal chooses the Edge trigger mode for Type and the video signal the Video. Only if a proper trigger mode is applied, the wave form can be displayed steadily.
    • Try to change the trigger coupling into the high frequency suppress and the low frequency suppress to smooth the high frequency or low frequency noise triggered by the interference.
