Acquire the Signal
6. Adjust the horizontal position and scale.
The horizontal position determines the
number of pretrigger and posttrigger
samples.
The horizontal scale determines the size
of the acquisition window relative to the
waveform. You can scale the window to
contain a waveform edge, a cycle, several
cycles, or thousands of cycles.
Quick Tip
Use the zoom feature to see multiple cycles of your signal in the upper part, and a single cycle in the lower part of the display.
(See page 224, Using Wave Inspector to Manage Long Record Length Waveforms .)
Labeling Channels and Buses
You can add a label to the channels and buses shown on the display for easy identi fi cation. The label is placed on the waveform
baseline indicator in the left side of the screen. The label can have up to 32 characters.
To label a channel, push a channel input button for an analog channel to label a channel.
