9.4 Screenshot
With the screenshot function, you can capture the image of the current screen. The
R&S LCX assigns a unique, generic filename and saves the file in *.png format.
How to: see Section 9.4.2, "Using the screenshot function", on page 129.
9.4.1 Screenshot settings
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/screenshot.
