Measurement of Simple Signals

Observe an unknown signal in the circuit, and display and measure rapidly the frequency and peak-to-peak voltage of the signal.

1. Carry out the following operation steps for the rapid display of this signal:

  1. Set the probe menu attenuation coefficient as 10X and that of the switch in the probe switch as 10X
  2. Connect the probe of Channel 1 to the measured point of the circuit.
  3. Push down the Autoset button.

The oscilloscope will implement the Autoset to make the waveform optimized, based on which, you can further regulate the vertical and horizontal divisions till the waveform meets your requirement.

2. Perform Automatic Measurement

The oscilloscope can measure most of the displayed signals automatically. To measure the period and frequency of the Channel 1 and the mean and peak-to-peak voltage of the Channel 2, follow below steps:

  1. Press the Measure button to show the automatic measurement function menu.
  2. Press the H1 to display the Add menu.
  3. Press the F2 button to choose CH1 as the source.
  4. Press the F1 button, the type items will display at the left of screen, and turn the M knob to choose Period.
  5. Press the F4 button, the period measurement will be added.
  6. Press the F1 button again, the type items will display at the left of screen, and turn the M knob to choose Freq.
  7. Press the F4 button, the frequency measurement will be added, finish settings of channel 1.
  8. Press the F2 button to choose CH2 as the source.
  9. Press the F1 button, the type items will display at the left of screen, and turn the M knob to choose Mean.
  10. Press the F4 button, the mean measurement will be added.
  11. Press the F1 button, the type items will display at the left of screen, and turn the M knob to choose PK-PK.
  12. Press the F4 button, the peak-to-peak voltage measurement will be added, finish settings of channel 2.

    Then, the period, frequency, mean and peak-to-peak voltage will be displayed at the bottom left of the screen and change periodically

Capture the Single Signal

The digital storage oscilloscope takes the lead in providing the convenience capturing of such non-periodic signals as pulse and burr, etc. If you intent to capture a single signal, you cannot set the trigger level and the trigger edge unless you have particular prior knowledge of this signal. For example, if the pulse is the logic signal of a TTL level, the trigger level should be set to 2 volts and the trigger edge be set as the rising edge trigger. If it is uncertain as to the signal, you can make an observation of it in advance under the automatic or ordinary mode to determine the trigger level and the trigger edge.

The operation steps are as follows:

  1. Set the probe menu attenuation coefficient to 10X and that of the switch in the probe to 10X
  2. Adjust the VOLTS/DIV and SEC/DIV knobs to set up a proper vertical and horizontal ranges for the signal to be observed.
  3. Press the Acquire button to display the Acquire menu.
  4. Press the H1 button to display the Acquire Mode menu.
  5. Press the F2 button to choose Peak detect.
  6. Press the Trigger Menu button to display the Trigger menu.
  7. Press the H1 button to display the Trigger Type menu.
  8. Press the F1 to choose Single as the type.
  9. Turn the M knob to choose Edge as the mode.
  10. Press the H2 button to display the Source menu.
  11. Press the F1 button to choose CH1 as the source.
  12. Press the H3 button to display the Coupling menu; press the F2 button to choose DC as the Coupling.
  13. Press the H4 button to choose (rising) as the Slope.
  14. Rotate the TRIG LEVEL knob and adjust the trigger level to the mid-value of the signal to be measured.
  15. If the Trigger State Indicator at the top of the screen does not indicate Ready, push down the Run/Stop button and start acquiring, waiting the emergence of the signal in conformity with the trigger conditions. If a signal reaches to the set trigger level, one sampling will be made and then displayed in the screen. With this function, any random occurrence can be captured easily. Taking the burst burr of larger amplitude for example, set the trigger level to the value just greater than the normal signal level, and then presses the Run/Stop button and waits. When there is a burr occurring, the instrument will trigger automatically and record the waveform generated during the period around the trigger time. With the HORIZONTAL POSITION knob in the horizontal control area in the panel rotated, you can change the horizontal position of the trigger position to obtain the negative delay, making an easy observation of the waveform before the burr occurs.

Measuring Gain of the Amplifier in the Metering Circuit

Set the probe menu attenuation coefficient as 10X and that of the switch in the probe as 10X.
Connect the oscilloscope CH1 channel with the circuit signal input end and the CH2 channel to the output end.

Operation Steps:

  1. Push down the Autoset button and the oscilloscope will automatically adjust the waveforms of the two channels into the proper display state.
  2. Push down the Measure button to show the Measure menu.
  3. Press the H1 button.
  4. Press the F2 button and choose CH1.
  5. Press the F1 button and turn the M knob to choose PK-PK.
  6. Press the F2 button and choose CH2.
  7. Press the F1 button again and turn the M knob to choose PK-PK
  8. Read the peak-to-peak voltages of Channel 1 and Channel 2 from the bottom left of the screen
  9. Calculate the amplifier gain with the following formulas.

    Gain = Output Signal / Input signal
    Gain (db) = 20•log (gain)

Analyze the Details of a Signal

Observe the Signal Containing Noises

If the signal is interfered by the noise, the noise may cause a failure in the circuit. For the analyzing of the noise in detail, please operate the instrument according to the following steps:

  1. Press the Acquire button to display the Acquire menu.
  2. Press the H1 button to display ACQU Mode menu.
  3. Press the F2 button to choose Peak detect.

In this case, the screen display contains the waveform of a random noise. Especially when the time base is set as Low Speed, then noise peak and burr contained in the signal can be observed with the peak detection.

Observe the Signal Containing Noises

Separate Noises from the Signal

When analyze the waveform of a signal, you should remove the noise in it. For the reduction of the random noise in the oscilloscope display, please operate the instrument according to the following steps:

  1. Press the Acquire button to display the Acquire menu.
  2. Press the H1 button to display ACQU Mode menu.
  3. Press the F3 button, turn the M knob and observe the waveform obtained from averaging the waveforms of different average number.

Application of X-Y Function

Examine the Phase Difference between Signals of two Channels

Example: Test the phase change of the signal after it passes through a circuit network.

Connect the oscilloscope with the circuit and monitor the input and output signals of the circuit.

For the examination of the input and output of the circuit in the form of X-Y coordinate graph, please operate according to the following steps:

  1. Set the probe menu attenuation coefficient for 10X and that of the switch in the probe for 10X.
  2. Connect the probe of channel 1 to the input of the network and that of Channel 2 to the output of the network.
  3. Push down the Autoset button, with the oscilloscope turning on the signals of the two channels and displaying them in the screen.
  4. Turn the VOLTS/DIV knob, making the amplitudes of two signals equal in the rough.
  5. Press the Display button and recall the Display menu.
  6. Press the H3 button and choose XY Mode as ON.
    The oscilloscope will display the input and terminal characteristics of the network in the Lissajous graph form.
  7. Turn the VOLTS/DIV and VERTICAL POSITION knobs, optimizing the waveform.
  8. With the elliptical oscillogram method adopted, observe and calculate the phase difference.

Based on the expression sin q=A/B or C/D, there into, q is the phase difference angle, and the definitions of A, B, C, and D are shown as the graph above. As a result, the phase difference angle can be obtained, namely, q =± arcsin (A/B) or ± arcsin (C/D). If the principal axis of the ellipse is in the I and III quadrants, the determined phase difference angel should be in the I and IV quadrants, that is, in the range of (0~π/2) or (3π/2~2π). If the principal axis of the ellipse is in the II and IV quadrants, the determined phase difference angle is in the II and III quadrants, that is, within the range of (π/2~π) or (π~3π/2).

    How to check the availability of the specified maximum memory depth (10 Mpts per channel) in ADS-2xxxM/ADS-2xxxMV series oscilloscopes?

    Variant 1.

    The memory depth can be easily checked in the special area of the device screen.

    Variant 2.

    You may calculate the memory depth automatically.

    1. Apply 1 MHz square signal from the generator to the oscilloscope

    2. Press “Auto” button of the oscilloscope to get the stable image.

    Here and further on it’s better to operate in the mode of dots signal mapping.

    3. Press ACQUIRE button to open the recording main menu. Then press H2 functional button to enter the mode of the memory depth specification and then press F5 to specify the memory depth of 10 Mpts.

    4. Stop the signal recording. Therefore press Run/Stop button of the oscilloscope.

    5. Zoom in the oscillogram to see the distance between the points.

    In the image you may see that the distance between the points corresponds to 1 division. With 1 ns/div sweep the points are located in 1 ns.

    6. Afterwards set the sweep to see the whole captured signal on the display. In our case the best sweep for the whole captured signal display is 5 ms/div.

    In this case the captured signal takes 2 divisions meaning that its length is 10 ms.

    7. Now you may calculate the quantity of points which can fit in the recorded signal. Therefore divide the recorded signal length of 10 ms by the distance between the points – 1 ns.

    Namely: 10 ms/1 ns = 10 Mpts.

    Thus you may see that the specified maximum memory depth of AWG series AKTAKOM oscilloscopes is correct – 10 Mpts.

    Variant 3.

    Memory depth calculation basing on the software.

    1. Apply a signal to CHA oscilloscope input. You will see the image just like in the picture below:

    2. Connect a storage device to the USB-port. Save the data on this storage device. Therefore press COPY button. The saving process can take several seconds.

    All further data proceeding will be on your PC.

    3. In the PC program for the saved data proceeding open “File” tab and then item “Open”. Select the saved file and confirm pressing “Open” key.

    4. Since the aim of this task is to confirm the possibility to save a signal with memory depth of 10 Mpts on the oscilloscope it means that signal data table will be much more convenient comparing to the graphics form. To show the signal as a data table click Data Table icon.

    5. You will see the oscilloscope data in a table form (pages from 1 up to 2000).

    6. By scrolling the pages up to the last one (with number 2000) you may make sure that the maximum memory depth achieves 10 Mpts/ch.

    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

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

    Please implement the following fault treatment procedure.

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

    Up

    After the Average value sampling is set in the Acqu Mode or the longer duration is set in the Persist in Display the display rate is slowed down

    It is a normal phenomenon.

    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 drivewith 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

    Next thing you need to do is to find your command prompt

    Once you get to command prompt you will need to type this:

    format /FS:FAT32 G:

    Note: You need to change the letter G to the letter of your drive
