The instrument stores in internal memory up to 16 waveform measurements (16
blocks)

that were measured with the same setting configuration
*1
(subse-
quently, the data acquired during each measurement will be referred to as a
“block”).
As a result, you can view some waveforms measured in the past.
*1 Past waveform data is deleted when you start measuring again after chang-
ing the configuration (recording length and channels used).
*2 Although the maximum number of such blocks is 16, the number of blocks is
reduced if the recording length is long. When all blocks are filled, the oldest
waveform (block) is overwritten.
