Using the Oscilloscope
3-6
Marker and Measurement Controls
Using the marker and measurement controls, you control two sets of
markers within the oscilloscope graticule. You use markers to make
more accurate measurements of waveform events than you could make
visually. Both time and voltage differences between the markers are
updated continuously on the screen. By default, the markers track the
source waveform. Voltage measurements from the markers are the value
of the waveform at the time set with the marker arrow keys.
The QuickMeas key initiates four preset measurements on the
waveforms. Both quick measurements and markers will function on any
input waveform; simply continue to press and release one of the keys
(either QuickMeas, Marker A, or Marker B) to cycle through all the
waveforms on the screen, then to the off state. You choose which four
measurements will be performed by using the measurement
configuration commands in the graphical interface.
