    Test Equipment Depot - 800.517.8431 - 99 Washington Street Melrose, MA 02176 TestEquipmentDepot.com Oscilloscope Bandwidth and Sample Rate The bandwidth of an oscilloscope is usually stated as the lowest frequency at which a sine wave's amplitude is measured as 30% lower than its actual value (this is equivalent to a 3 dB drop in power because 20log(1/sqrt(2)) is -3).

  • Page 48: Memory Depth

    -3dB Attenuation Aliased frequency components Frequency Limiting oscilloscope bandwidth (f ) to ¼ the sample rate (f reduces frequency components above the Nyquist frequency (f Figure 29 Bandwidth and Nyquist frequency In practice, an oscilloscope's sampling rate should be four or more times its bandwidth: f = 4f This way, there is less aliasing and the aliased frequency components have a greater amount of attenuation.

  • Page 49: Sampling Mode

    Limiting the oscilloscope bandwidth (f ) to 1/4 the sample rate will reduce frequencies above the Nyquist frequency. 4.4 Sampling Mode The oscilloscope only supports real-time sampling. In this mode, the oscilloscope samples and directly displays the waveform containing a trigger event. The maximum real-time sample rate of the oscilloscope is 2 GSa/s.

The oscilloscope provides the following acquisition modes: Normal, Peak Detect, Average and Eres.

  • Page 53: Average

    Figure 34 - Pulse with 0.1% duty cycle, normal mode Figure 35-Pulse with 0.1% duty cycle, peak detect mode Average In this mode, the oscilloscope averages the waveforms from multiple frames to reduce the random noise of the input signal and improve the vertical resolution.
  • Page 54 When the number of waveform averages is large, the noise will be lower and the vertical resolution will be better. However, the response time for changes in the signal will be lower because of the need to capture the extra frames. The number of frames averaged are 4, 16, 32, 64, 128, 256, 512, and 1024.

  • Page 55: Eres (Enhanced Resolution)

    Figure 37 - Random noise averaged out Eres (Enhanced Resolution) Eres mode uses a digital filter to reduce the random noise on the input signal and generate smoother waveforms. Eres can be used on both single-shot and repetitive signals and it does not slow down the waveform update speed.

This oscilloscope provides a variety of trigger types: Edge, Slope, Pulse, Video, Window, Interval, Dropout, Runt, Pattern and Serial Bus (I2C/SPI/UART/RS232/CAN/LIN).

  • Page 60: Auto Setup

    Note: the 2560 Series oscilloscopes allow the use of either voltage or current units for waveform measurements. The remainder of this chapter will refer to just voltages, but it applies to current levels, too. 5.2 Auto Setup The oscilloscope automatically identifies the waveform type, trigger level, and scales to produce a usable display of the input signal.

  • Page 61: Trigger Source

    Figure 43 - Acquisition Memory Schematic Choosing the right trigger mode and setting it up correctly can take some practice and it is best done if you know something about the signal you are trying to capture. The oscilloscope provides a variety of triggering types and logical conditions for generating a trigger event, such as Edge, Slope, Pulse, Video, Window, Interval, Dropout, Runt, Pattern and Serial triggering.

    6 Math Functions The 2560 Series oscilloscopes support math operations between the analog channels and reference waveforms, including addition ( + ), subtraction ( - ), multiplication ( * ), division ( / ), FFT, differentiation ( d/dt ), integration (∫dt), and taking the square root (√). The resulting math waveform is displayed in white and labeled with the letter M at the left of the screen.
