Select the Time Base
Press the main menu button Time Base. Use the
side menu to select from these options.
H Press Main Only to show only the main time base.
H Press Intensified to show both the main and delayed time bases. The
oscilloscope intensifies a portion of the waveform; this intensified zone
indicates the location of the delayed time base with respect to the main.
Use the SEC/DIV knob to change the length of the zone and the General
Purpose Knob to change its position.
H Press Delayed Only to show only the delayed time base.
H Use the General Purpose Knob to adjust the delay time (the interval
between the main and delayed time bases). You adjust the delay time in
coarse increments when Main Only or Intensified are selected and in fine
increments when Delayed Only is selected. The side menu selection
Delayed Runs After Main shows the delay time.
H Press SET to Min to set the delay time to its minimum value.
Adjust Horizontal Trigger Position
Press the main menu button
Trigger Position. Use the General Purpose Knob to adjust horizontal trigger
position, or use side menu selections to set the trigger position to 10%, 50%,
or 90% of the waveform record.
TDS 300 Series oscilloscopes can add or multiply the two channel waveforms
or subtract one from the other and display the result as a math waveform. To
activate the math waveform, press the MATH button, shown in Figure 39.
