respective unit per grid in the diagram. The colored bar of each softkey corre-
sponds to the trace color.

8.8.3 Logging
The logging function enables you to record the measurement data. You can save the
readings on the internal memory of the R&S LCX, or on an externally connected mem-
ory device, e.g. a USB flash drive. The function saves the data in a .csv file with a
generically generated filename.
Aspects on the logging function:
●
The R&S LCX does not support external USB hard disk drives (or USB exten-
sions).
We recommend that you use USB flash drives with FAT/FAT32 formatting. The
instrument recognizes the USB device automatically.
