Selecting a Global Bandwidth Limit and Vertical Resolution
Limiting the channel bandwidth with digital filters lets you remove unwanted high
frequency noise from the waveform and potentially increase the number of bits of
vertical resolution.
To select a global channel bandwidth limit and vertical resolution:
1 Open the Acquire dialog box by selecting the sample rate and memory depth
(Acquire) badge or by choosing Setup > Acquire... from the main menu.
2 In the Acquire dialog box, use the Global BW Limit drop-down list to disable or
enable global channel bandwidth limiting.
The selections that improve the number of bits of vertical resolution are marked
with "HD" (high-definition).
Note that each channel also has an independent 40 MHz BW Limit option. See
"To
specify bandwidth limiting"
on page 59. When the global bandwidth limit and an
individual channel bandwidth limit are both selected, the lower bandwidth limit is
applied.
Acquiring to Segmented Memory
When capturing multiple infrequent trigger events it is advantageous to divide the
oscilloscope's memory into segments. This lets you capture signal activity without
capturing long periods of signal inactivity.
Each segment is complete with all analog channel, digital channel, and serial
decode data.
