USB
RSA3000E provides a USB DEVICE interface on the rear panel. The analyzer may
serve as a "slave" device to be connected to the PC via this interface.
Display

interface or window, and other display-related parameters.
1.
Display Line State
Turns on or off the display line.
2.
Display Line
Sets the display line level to change its display location. This line can be used as
either the reference for you to read the measurement result or the threshold
condition for the peaks displayed in the peak table.
Remarks:
This line is a horizontal reference of which the amplitude is equal to the set
value, and the corresponding amplitude unit is the same as the Y-axis unit.
You can use the numeric keys, the knob, and the arrow keys on the front
panel to modify the display line level; also you can modify it on the
touchscreen. For details, refer to descriptions in "Parameter Setting".
If the display line is out of the visible range, it will be displayed at the top or
bottom of the graticule, and indicated by arrows.
