  • Page 40: Horizontal Controls

    Horizontal Controls The oscilloscope shows the time per division in the status bar. Since all waveforms use the same time base, the oscilloscope only displays one value for all channels, except when you use Delayed Sweep. The horizontal controls can change the horizontal scale and position of waveforms.

Choosing the X-Y display format displays channel 1 on the horizontal axis and channel 2 on the vertical axis.
  • Page 46 Horizontal Controls Horizontal Menu Holdoff Holdoff can be used to stabilize a waveform. The holdoff time is the oscilloscope's waiting period before starting a new trigger. During the holdoff time oscilloscope will not trigger until the holdoff has expired. Figure 2-17 Holdoff The following exercise guides you through setting the holdoff time.

  • Page 47: Roll Mode

    Horizontal Controls Roll Mode Roll Mode Roll mode continuously moves data across the display from left to right. It allows you to see dynamic changes (like adjusting a potentiometer) on low frequency waveforms. Two frequently used applications are transducer monitoring and power supply testing.

  • Page 48: Trigger Controls

    Trigger Controls The trigger determines when the oscilloscope starts to acquire data and display a waveform. When a trigger is set up properly, it can convert unstable displays or blank screens into meaningful waveforms. The oscilloscope acquires data while waiting for the trigger condition to occur. After it detects a trigger, the oscilloscope continues to acquire enough data so that it can draw the waveform on the display.
