Help and autoset can assist you in setting up the Digitizing Oscilloscope to
make your measurements.
Help displays operational information about any frontĆpanel control. When
help mode is in effect, manipulating any frontĆpanel control causes the
Digitizing Oscilloscope to display information about that control. When help
is first invoked, an introduction to help is displayed on screen.
Autoset automatically sets up the Digitizing Oscilloscope for a viewable
display based on the input signal.
Once you have set up to make your measurements, the cursor and measure
features can help you quickly make those measurements.
Three types of cursors are provided for making parametric measurements
on the displayed waveforms. Horizontal bar cursors (H Bar) measure vertical
parameters (typically volts). Vertical bar cursors (V Bar) measure horizontal
parameters (typically time or frequency) and now extend to the top and
bottom of the screen. Paired cursors measure both amplitude and time
simultaneously. These are delta measurements; that is, measurements
based on the difference between two cursors.
Both H Bar and V Bar cursors can also be used to make absolute measureĆ
ments; that is measurements relative to a defined level or event. For the
H Bars, either cursor can be selected to read out its voltage with respect to
any channels ground reference level. For the V Bars, it's time with respect to
the trigger point (event) of the acquisition and the cursors can control the
portion of the waveform on which automatic measurements are made.
For time measurements, units can be either seconds or Hertz (for 1/time).
When the video trigger option installed (Option 05), you can measure the
video line number using the vertical cursors. You can measure IRE ampliĆ
tude (NTSC) using the horizontal cursors with or without the video trigger
option installed.
Measure can automatically extract parameters from the signal input to the
Digitizing Oscilloscope. Any four out of the more than 25 parameters availĆ
able can be displayed to the screen. The waveform parameters are meaĆ
sured continuously with the results updated onĆscreen as the Digitizing
Oscilloscope continues to acquire waveforms.
