MULTI Part of MATH+ option. Refer also to MATH+ Users Manual. The
MULTIple shot mode enables a number of single shot acquisitions
to be made in rapid succession. It is basically the same as SINGLE
but with automatic rearming following each acquisition. Each
acquired waveform is stored in a different memory location.
ROLL In the ROLL mode, the MAIN TB can be used with sweep speeds
from 200 ms/div down to 200 s/div. Initially the trace fills the
screen from the right to the left. Once the screen is full, the trace
flows 'through' the screen from left to right. When ROLL is
selected, the TB MODE menu provides a 'STOP ON TRIGGER'
choice. If this is set to 'off', the trace flows through the screen
continuously until you press the STOP key. If 'STOP ON
TRIGGER' is set to 'on', the trace stops when the scope is
triggered and the trigger point reaches the left of the screen.
REAL TIME In the digital mode the scope operates in random sampling mode
ONLY for sweep speeds 200 ns and faster. Setting 'REAL TIME ONLY'
to 'on' means that these MAIN TB positions are inhibited. This
measuring errors on signals that are not truly repetitive or
identical. REAL TIME ONLY also inhibits alternating acquisitions
of MAIN TB and DEL'D TB.
