2 Press the Intensity softkey; then, turn the Entry knob to change the
intensity of the displayed grid.
The intensity level is shown in the Intensity softkey and is adjustable from
0 to 100%.
Each major vertical division in the grid corresponds to the vertical
sensitivity shown in the status line at the top of the display.
Each major horizontal division in the grid corresponds to the time/div
shown in the status line at the top of the display.
To display waveforms as vectors or dots
Agilent InfiniiVision 4000 X- Series oscilloscopes are designed to operate
optimally with vectors (connect the dots) on. This mode produces the
most insightful waveforms for most situations.
On the 1 GHz and 1.5 GHz bandwidth models, you can disable vectors to
view just waveform data points.
To disable or re- enable vectors:
1

.
2 Press Vectors .
When enabled, Vectors draws a line between consecutive waveform data
points.
• Vectors give an analog look to a digitized waveform. Complex analog
signals like video and modulated signals show analog- like intensity
information with vectors on.
• Vectors allow you to see steep edges on waveforms, such as square
waves.
• Vectors allow subtle detail of complex waveforms to be viewed, much
like an analog oscilloscope trace, even when the detail is just a small
number of pixels in size.
You may want to turn vectors off when highly complex or multivalued
waveforms are displayed. Turning vectors off may aid the display of
multivalued waveforms such as eye diagrams.
