How to do longer recordings (1-4 HOURS)?
Can entire recording be saved in the computer? I mean the entire let’s say 1 hr. recording (all the readings and all of the screens), not just current screen?
Yes, you can save the entire recording of any length:
- Select from the File menu the option ”AutoSave Data”.
- Enter a file name and click ”Save”.
- Click the ”Run” button to start the recording.
- Recording stops when you next time click the ”Run” button. The data will be saved to file.
To view all the recorded data screens:
- Select from the File menu the option “Open Data” and open the file.
- Now you can view the whole record using the arrow buttons next to the horizontal scroll bar.
- In the View menu click Markers dV & t to check the time and voltage. You can move the markers on the screen using the mouse.
- You can ‘zoom’ the recorded data by selecting different Time/Div setting.
The data saved to the file is in text (.TXT) format.
You can open this file in any spreadsheet program to view the whole record.

OK, that applies only to “TRANSIENT” mode, doesn’t it?
It can’t be done in the "SCOPE MODE?

[quote]It can’t be done in the "SCOPE MODE?[/quote]I’m sorry this is not possible in the oscilloscope mode.
Due to the operation principle of the oscilloscope, the continuous capture is not possible. A chunk of the data is stored to the oscilloscope’s RAM and then transferred to the PC via USB. This is why the continuous data stream is not possible.
The internal data buffer is 4096 samples/channel. This is the maximum amount of continuous data to record. The buffer must be read to the PC before the next data can be acquired.
The USB communication used is too slow to transfer the data in “real time”.
This is why in the oscilloscope mode the acquired data is always intermittent.
In some cases there may be a workaround to use the “History”.
