4.6.2.2 Analyzing waveform data
The data displays available for acquired waveform data allow you to scroll
through the entire acquisition buffer. For waveform displays, the knob can be
used to scroll through the display horizontally. The UP and DOWN cursor keys
have no effect in this display mode.
Figure 4-39: Scrolling Through Acquired Waveform Data
The acquisition buffer may be longer than the selected horizontal scale in which
case only a portion of the acquisition window will be visible. The left portion of
the LCD display is used to read out the data under the vertical cursor. This
cursor is a dotted line that can be moved using the knob. If the left or right
edge of the display window is reached, the entire display will shift so the cursor
always remains visible. The time from the trigger point to the vertical cursor is
displayed in the left-hand portion of the LCD in ms. Also displayed here are the
absolute voltage and/or current value under the cursor.
To change the horizontal display scale without re-triggering an acquisition, press
the ENTER key to return to the HARMONICS/TRACE ANALYSIS screen, change
the SCALE value, move the cursor to the VIEW field and press ENTER. This will
display the same data set at the new scale without triggering a new acquisition.
