Acquisition
Acquisition
The acquisition settings include everything required to produce a visible trace on screen and an acquisition
record that may be saved for later processing and analysis:
l Vertical axis scale at which to show the input signal and probe characteristics that affect the signal
l Horizontal axis scale at which to represent time, and acquisition sampling mode and sampling rate
l Acquisition trigger mechanism
Optional acquisition settings include bandwidth filters and pre-processing effects, vertical offset, and
horizontal trigger delay, all of which affect the appearance and position of the waveform trace.
Vertical
Vertical, also called Channel, settings usually relate to voltage level and control traces along the Y axis.
Note: While Digital settings can be accessed through the Vertical menu on Mixed Signal
oscilloscopes, they are handled quite differently. See Digital.
The amount of voltage displayed by one vertical division of the grid, or Vertical Scale (V/div), is most
quickly adjusted by using the front panel Vertical knob. The Cn descriptor box always shows the current
Vertical Scale setting.
Detailed configuration for each trace is done on the Cn dialogs.
Cn (Channel) Dialog
Full vertical setup is done on the Cn dialog. To access it, choose Vertical > Channeln Setup from the menu
bar, or touch the Channel descriptor box.
The Cn dialog contains:
l Vertical settings for scale, offset, coupling, bandwidth
l Units settings
l Probe attenuation and deskew
If a Teledyne LeCroy probe is connected, its Probe dialog appears to the right of the Cn dialog.
