Characteristics Performance Requirements
SAVE Mode Expansion or Compression
Range
Up to 10 times as determined by the remaining VOLTS/DIV
switch positions up or down.
2 mV per division acquisitions cannot be expanded, and 5 V
per division acquisitions cannot be compressed.
Any portion of a stored waveform vertically magnified or com
pressed up to 10 times can be positioned to the top and to
the bottom of the graticule area.
