The TIME_DIV command modifies the time-base setting. The
new time-base setting may be specified with suffixes NS for
nanoseconds, US for microseconds, MS for milliseconds, S for
seconds or KS for kiloseconds. An out-of-range value causes the
VAB bit (bit 2) in the STB register (Table 8, STB) to be
The oscilloscope will force random interleaved sampling (RIS) for
time-base settings in the "ON" only range, and single-shot sam-
piing for time-base settings in the "OFF" only range. For
time-base settings in the "Selectable" range, the INTERLEAVED
command allows the user to choose the required sampling mode.

Sequence mode acquisitions also force single-shot sampling and
therefore cannot be performed for time-base settings in the RIS
"ON" only range (see table above).
The TIME DIV? query returns the current time-base setting.
