Saving Data
Auto save (real-time save)
This section describes how to save waveform data (using the real-time save function) to media (an
SD Memory Card or USB Drive) while measurement is in progress.
Numerical calculation results can also be saved to media automatically.
You can also save both waveform data and numerical calculation results automatically.
The following measurement data can be saved automatically:
Saved data Setting File extension Description
Waveform data Binary format .MEM Waveform data will be saved in the instrument’s
dedicated format (binary format) while
measurement continues.
Ordinarily, it is recommended to use the [Binary]
setting.
Text format .CSV, .TXT* Waveform data will be saved in the CSV format
while measurement continues.
Although the data can be loaded using
spreadsheet software, it cannot be loaded by the
instrument or the Logger Utility.
Numerical
calculation
results
Text format .CSV, .TXT* Numerical calculation results will be saved after
measurement stops.
*: If a setting other than [Comma] is selected under [Delimiter] , the extension is set to [.TXT] .
Text format (CSV) limitations
Auto save is subject to limitations depending on the recording interval.
• Recording interval of 1 ms to 5 ms: Auto save is not supported.
• Recording interval of 10 ms: Auto save is not supported for 61 or more channels.
Data protection (When Z1007 Battery Pack is used)
The instrument will stop saving data when the battery starts to run out during auto-save operation
(Measurement will continue).
Media crash, which can occur because of system shutdown during saving operation, can be
prevented.
