Additional Channels Settings (Oscilloscope)

Version:
    Last Modified: May 14, 2018

    Use configuration options in the Additional Channels section to perform a 16K-point fast Fourier transform (FFT) or mathematical operations on the signal, or to configure a reference channel.

    You can configure some settings directly on the panel. To access additional settings, click the configuration button on the top right side of the section.

    Use the following settings to configure the FFT channel:

    Setting Description
    Status Enables or disables fast Fourier transform on the source channel.
    Window Time-domain window to apply to the signal.
    Source channel Source channel on which you want to perform fast Fourier transform.
    Start frequency Frequency at the extreme left of the horizontal axis.
    Stop frequency Frequency at the extreme right of the horizontal axis.
    Display Description
    Center frequency Frequency that is at the center of the horizontal axis.
    Span Range between the start frequency and the stop frequency.
    Reference level Maximum expected power of the input signal. The Oscilloscope automatically sets Reference level based on the value of Volts per division.
    Resolution bandwidth The horizontal scale.
    Record length Range of the X axis on the time domain graph.

    Use the following settings to configure the math channel:

    Setting Description
    Status Enables or disables math operation on the source channels.
    Function Math operation you want to perform on the channels.
    A source First source channel.
    B source Second source channel.
    Volts per division The vertical scale of the display.
    Vertical position Vertical positioning of the waveform on the graph. This value is not applied to the actual acquired data. Use Vertical position to move the waveform up and down the graph. The range of Vertical position is -100 V to 100 V.

    Use the following settings to configure a reference channel:

    Setting Description
    Status Enables or disables sourcing data from another channel.
    Mode Data sources for the reference channels. When you select Load from file, the Oscilloscope loads data from a data file. You specify the path to the file in Source file.
    Source file Path to the data file. You can load CSV files from Multisim and Multisim Live and TDMS files from LabVIEW. The TDMS files must contain only analog waveform data. You can also load CSV or TDMS files exported from the Oscilloscope.
    Source file channel Channel you want to import. If the source data file contains data of multiple channels, you can use Source file channel to select which channel of data you want to import to the Oscilloscope.
    Volts per division The vertical scale of the display.
    Vertical position Vertical positioning of the waveform on the graph. This value is not applied to the actual acquired data. Use Vertical position to move the waveform up and down the graph.

    The following settings are available on the panel only:

    Setting Icon Description
    Include "Off" Displays or hides disabled channels on the configuration pane.
    Expand Expands the trace.
    Shrink Contracts the trace.
