Demonstration Preparation

All demonstrations use an X-Series 

signal analyzer with the phase noise 

measurement application and the 

N5181A MXG analog signal generator 

(unless otherwise noted). Keystrokes 

surrounded by [ ] indicate front-panel 

keys; keystrokes surrounded by  

{ } indicate softkeys located on the 

display.

Demonstration Setup

Connect the X-Series and MXG

Perform the following steps to  

interconnect the X-Series and MXG 

(see Figure 1 for a graphical overview):

A.  Connect the MXG RF output port 

to the X-Series RF input port with 

a 50 Ω RF cable

B.  Connect the MXG “REF IN” to the 

X-Series “10 MHz OUT” port (rear 

panel) with a BNC cable

Helpful tip:

Update your instrument firmware and software  

to the latest version, available at
