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.

Frequently Asked Questions

  • High voltage measurement testing are not allowed over 300 volts
  • The measured voltage amplitude value is 10 times greater or smaller than the actual value
  • 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?
  • Backlight adjust function is not available for this HDS model
  • There is wave form displayed, but it is not stable

  • 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

    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

    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

    Backlight adjust function is not available for this HDS model

    The backlight adjust function is only available for the following HDS models:

    • HDS3102M-N
    • HDS2062M-N


    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.
