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.

Measuring Ring Amplitude

Catch the single signal

To capture a single event, you need to gather some pre-test knowledge of the signal in order to correctly set up the trigger level and slope. If you are not sure the instance of the signal, you can observe it through auto or normal trigger mode to ensure the trigger level and slope.

The following steps show you how to use the oscilloscope to capture a single event.

1. Set the Probe option attenuation to 10X and set the switch to 10X on the probe.
2. Trigger set up:

  • Press “TRIG MENU” button to show the “Trigger Menu”
  • Under this menu, set the trigger type to “edge”, Edge type is “Rising”, source is “CH1”, trigger mode is “Single”, coupling is “DC”
  • Adjust the horizontal time base and vertical scale to the satisfied range
  • Turn the “LEVEL” knob to adjust the trigger level
  • Press the “RUN/STOP” button to start capturing

When the trigger conditions are satisfied, data appears on the display representing; the data points that the oscilloscope obtained with one acquisition and press the RUN/STOP button again rearms the trigger circuit and erases the display.

Analyze the signal detail

You have a noisy signal displayed on the oscilloscope and you need to know more about it. You suspect that the signal contains much more detail than you can now see in the display.

Looking at a Noisy Signal

The signal appears noisy and you suspect that noise is causing problems in your circuit. To analyze the noise better, follow these steps:

  • Press the ACQUIRE button to see the acquire menu.
  • Press the Acquisition option button or turn the Universal knob to select Peak Detect.
  • If necessary, press the DISPLAY button to see Display menu. Turn the Universal knob to adjust waveform intensity and grid brightness to see the noise more clearly.
  • Peak detect emphasizes noise spikes and glitches in your signal, specially when the time base is set to a slow setting.

Separating the Signal from Noise

To reduce random noise in the oscilloscope display, follow these steps:

  • Press the ACQUIRE button to display the acquire menu.
  • Press the Acquisition option button or turn the Universal knob to select Average.
  • Press the Averages option button to see the effects of varying the number of running averages on the waveform display.

Averaging reduces random noise and makes it easier to see the details of a signal.

Triggering on a Video Signal

Observe the video circuit in a piece of medical equipment and Use the video trigger to obtain a stable display.

Viewing Impedance Changes in a Network

Connect the oscilloscope to monitor the input and output of the circuit. To view the input and output of the circuit in an X-Y display, follow these steps:

  • Press the CH1 MENU button and set the Probe option attenuation to 10X.
  • Press the CH2 MENU button and set the Probe option attenuation to 10X.
  • Set the switch of the probe to 10X.
  • Connect the channel 1 probe to the input of the network, and connect the channel 2 probe to the output.
  • Press the AUTO button.
  • Turn the Volts/div knobs to display approximately the same amplitude signals on each channel.

  • Turn the VOLTS/DIV and VERTICAL POSITION knobs to optimize the display.
  • Press the Persist option button and select Infinite.
  • Press the Intensity or Brightness option buttons and turn the Universal” knob to adjust the contrast of the screen.
  • Apply the Ellipse method to observe the phase difference between the two channels

Application of X-Y function

Sin=A/B or C/D where =phase shift (in degrees) between the two signals from the formula above, you could get:=arcsine(A/B) or arcsine(C/D). If the main axis of the ellipse is at I and IV quadrant, must be in the range of (0~π/2) or (3π/2~2π). If the main axis is at II and III quadrant, must be in the range of (π/2~π) or (π~3π/2).

Analyzing a Differential Communication Signal

You are having intermittent problems with a serial data communication link, and you suspect poor signal quality. Set up the oscilloscope to show you a snapshot of the serial data stream so you can verify the signal levels and transition times.

Because this is a differential signal, you use the math function of the oscilloscope to view a better representation of the waveform.

To activate the differential signals connected to channel 1 and channel 2, follow these steps:

  • Press the CH1 button and set the Probe option attenuation to 10X.
  • Press the CH2 button and set the Probe option attenuation to 10X.
  • Set the switches to 10X on the probes.
  • Press the AUTO button.
  • Press the MATH button to see the Math Menu.
  • Press the Operation option button and select - .
  • Press the CH1-CH2 option button to display a new waveform that is the difference between the displayed waveforms.
  • You can adjust the vertical scale and position of the Math waveform.
    To do so, follow these steps:
    A. Remove the channel 1 and channel 2 waveforms from the display.
    B. Turn the CH1 and CH2 VOLTS/DIV and VERTICAL POSITION knobs to adjust the vertical scale and position.

Note: First be sure to compensate both probes. Differences in probe compensation appear as errors in the differential signal.

    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.

    How to save data in a USB Flash Drive

    This oscilloscope allows you to save data to an external USB Flash Drive only if the drive is formatted with FAT32.

    If you haven't noticed one huge change with Windows 7 is that FAT32 is no longer an option on formatting drives. You are now left with the options of either NTFS or exFAT. OK so your asking what is exFAT? Well its not FAT32, acutally its compatible with FAT64.

    So let's Format external USB Flash drive with FAT32 using DOS

    First you need to find what your Hard Drive is named (the label) that is easy to do right click on the hard drive and it will show you in the top box. As you can see mine has no level in the picture bellow. You also need to note which drive letter it is. Mine is Drive: G
