On-Board User Assistance
Help and autoset can assist you in setting up the oscilloscope to make your
measurements.
Help displays operational information about any front-panel control. When help
mode is in effect, manipulating any front-panel control causes the oscilloscope to
display information about that control. When help is first invoked, an introduc-
tion to help is displayed on screen.
Autoset automatically sets up the oscilloscope for a viewable display based on
the input signal.
Measurement Assistance
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 parame-
ters (typically volts). Vertical bar cursors (V Bar) measure horizontal parameters
(typically time or frequency). 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 measurements.
For the H Bars, either cursor can be selected to read out its voltage with respect
to any channel’s ground reference level. For the V Bars, the cursors measure time
with respect to the trigger point (event) of the acquisition. The cursors can also
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).
With the video trigger option installed (Option 05), you can measure the video
line number using the vertical cursors. You can measure IRE amplitude (NTSC)
using the horizontal cursors with or without the video trigger option installed.
Measure can automatically extract parameters from the signal input to the
oscilloscope. Any four out of the 25 parameters available can be displayed to the
screen. The waveform parameters are measured continuously with the results
updated on-screen as the oscilloscope continues to acquire waveforms.
