Learn the Oscilloscope Display
The oscilloscope display contains acquired waveforms, setup information, 
measurement results, and the softkey definitions.
1. Power cord 
connector
Attach the power cord here.
2. Kensington lock 
hole
This is where you can attach a Kensington lock for securing the instrument.
3. Module slot A DSOXLAN LAN/VGA module may be ordered and installed separately.
• LAN port — lets you communicate with the oscilloscope and use the 
Remote Front Panel feature using the LAN port. See Chapter 23, “Web 
Interface,” starting on page 359 and “Accessing the Web 
Interface" on page 360.
• VGA video output — lets you connect an external monitor or projector to 
provide a larger display or to provide a display at a viewing position 
away from the oscilloscope.
The oscilloscope's built-in display remains on even when an external 
display is connected. The video output connector is always active.
For optimal video quality and performance, we recommend you use a 
shielded video cable with ferrite cores.
A DSOXGPIB GPIB module may be ordered and installed separately.

7. USB Host port This port functions identically to the USB host port on the front panel. USB 
Host Port is used for saving data from the oscilloscope and loading 
software updates. See also USB Host port (see page 43).
8. USB Device 
port
This port is for connecting the oscilloscope to a host PC. You can issue 
remote commands from a host PC to the oscilloscope via the USB device 
port. See “Remote Programming with Keysight IO Libraries" on 
page 366.
