    Do not connect or disconnect probes or test leads while they are connected to a voltage source. Use only insulated voltage probes, test leads, and adapters supplied with the product, or indicated by Tektronix to be suitable for the product.
  • Page 12 Important safety information Category (CAT) rating and voltage or current rating of the lowest rated individual component of a product, probe, or accessory. Use caution when using 1:1 test leads because the probe tip voltage is directly transmitted to the product. Do not apply a potential to any terminal, including the common terminal, that exceeds the maximum rating of that terminal.

  • Page 13: Service Safety Summary

    Important safety information Beware of high voltages. Understand the voltage ratings for the probe you are using and do not exceed those ratings. Two ratings are important to know and understand: The maximum measurement voltage from the probe tip to the probe reference lead The maximum floating voltage from the probe reference lead to earth ground These two voltage ratings depend on the probe and your application.

  • Page 42: Sampling Oscilloscope Concepts

    Sampling oscilloscope concepts Sampling oscilloscope concepts Read this section if you are a new oscilloscope user, or are new to using a digital oscilloscope. Sampling and acquisition concepts Before the oscilloscope can display or measure a signal, it must be sampled. Sampling is the process of measuring the input signal amplitude value at regular intervals (called the sampling rate, in samples per second), converting the sampled levels into digital data, and storing the sampled values in memory to create a waveform record.
  • Page 43 Sampling oscilloscope concepts Acquisition mode concepts The acquisition mode sets how the oscilloscope uses the sampled data points in each acquisition interval to create and display a waveform. You can set the acquisition mode to one of the following modes. Sample mode retains and uses the first sampled point from each acquisition interval to create the displayed waveform.

  • Page 44: Trigger Concepts

    Sampling oscilloscope concepts Trigger concepts The oscilloscope uses the data in the waveform record to construct and display a waveform on the oscilloscope screen. However, as the oscilloscope is constantly acquiring samples into the waveform record, each waveform record starts at a random point of the input signal.

  • Page 45: Trigger Slope And Level Concepts

    Sampling oscilloscope concepts Pretrigger data can help you troubleshoot signal problems. For example, to find the cause of an unwanted glitch in your test circuit, trigger on the glitch signal and look at the pretrigger waveform. By analyzing what happens before the glitch, you may uncover information that helps you find the source of the glitch.

  • Page 46: Trigger Coupling

    Sampling oscilloscope concepts Trigger type Trigger conditions Edge Edge triggers are the simplest and most commonly used trigger type. An edge trigger event occurs when the trigger source passes through a specified voltage threshold (trigger level) when the signal is transitioning in the specified slope (rising or falling). You can trigger on a rising or falling edge, as defined by the slope control.
  • Page 47 Sampling oscilloscope concepts Auto mode, when forcing triggers in the absence of valid triggering events, does not synchronize the waveform on the display. The waveform will appear to roll across the screen. If valid triggers occur, the display will become stable. Normal trigger mode.

  • Page 48: Setting Channel Input Parameters

    Setting channel input parameters Setting channel input parameters Use the vertical Menu buttons to select waveforms to display or open menus and submenus with which to set input parameters for each channel. Each channel’s settings are independent of every other channel. Setting input signal coupling Input signal coupling sets how the input signal is passed to the oscilloscope sampling circuit.

  • Page 49: Setting The Oscilloscope Bandwidth

    Setting channel input parameters Setting the oscilloscope bandwidth Use this procedure to set the oscilloscope bandwidth. Bandwidth is the maximum frequency that an oscilloscope can accurately display and measure. The oscilloscope gradually attenuates (reduces) the signal level of frequencies that are higher than the bandwidth.

  • Page 50: Setting The Probe Attenuation Factor

    Setting channel input parameters Setting the probe attenuation factor Attenuation is the amount that the probe reduces or amplifies the input signal amplitude before sending it to the oscilloscope input. The Attenuation submenu sets the probe attenuation factor for probes that do not have the TekProbe II or TekVPI interface.

    Trigger setup Triggering on a specified pulse width Use this procedure to set the oscilloscope to trigger on a specified signal pulse condition. You can trigger when a pulse is less than, greater than, equal to, or not equal to a set time period (width). The minimum pulse width setting is 1 ns. (See page 27, Available trigger types.) Pulse width triggering is most often used to troubleshoot or analyze digital signals.

  • Page 56: Triggering On A Runt Pulse

    Trigger setup Triggering on a runt pulse Use this procedure to set the oscilloscope to trigger when a runt pulse occurs. You can also trigger when a runt pulse is less than, greater than, equal to, or not equal to a set time period (width). A runt pulse is a pulse that crosses one threshold level but fails to cross a second threshold before recrossing the first.
