CH 1 and CH 2 POSITION C o n tro ls —Adjust vertical position of the
Channel 1 and Channel 2 waveform displays.
11) MODE B u tto ns—Select the vertical channels for display (CH 1, ADD
channels 1 and 2, CH 2, CH 3, and CH 4). The CHOP/ALT MODE button
selects method for switching input channels on the display (chopped or

CHOP/ALT—in the CHOP mode the display chops between selected
Input channels at a rate of about 625 kHz, In the ALT mode, the selected
channels are displayed in sequence (alternating at the end of each
sweep).
ADD—Displays the algebraic sum of the Channel 1 and Channel 2
input signals. The ADD display is in addition to any other selected chan
nel displays, in the ADD mode, a plus sign { + ) isdisplayed between the
Channel 1 and Channel 2 VOLTS/DIV readouts.
NOTE
