Set the Record Length
Background
The number of samples that can be stored is set by
the record length. Record length is important in an
oscilloscope as it allows longer waveforms to be
recorded and/or allows higher sampling rates to
be achieved when equivalent time sampling is
used.
There are two record length settings, Auto and
Short. The Auto setting will set the record length to
maximum record length available, dependent on
the scope settings. The Short setting will set the
record length to 1M.
The maximum record length for the GDS-2000A
depends on the number of active channels, which
channels are active, and whether the normal or
single shot triggering mode is used. The table
below describes the record lengths that are
available for each triggering mode.
