In the "Logging" menu, you can configure the main parameter settings for data logging.
With a USB flash drive connected, you can save the file on either the USB flash drive
or the internal memory, with "USB1A" as default setting. Without USB connected, the
R&S LCX saves the file internally in the file path /int/logging.
Access:
1. Press the [settings] key at the front panel.
2. In the "Functions" tab, select "Logging".

The settings dialog contains the basic parameters for setting the logging mode,
and provides access to file management parameters.
The required remote commands are described in Section 11.14, "LOG subsystem",
