Demonstrations

Demonstration 1: 

Getting started

The signal under test is simply a 

continuous-wave (CW) RF signal from 

the MXG. Recommended settings 

for signal generator are 1 GHz center 

frequency and –10 dBm RF output 

level.

Instructions  

Keystrokes

On the MXG signal generator

Preset the MXG

[Preset]

Set up the signal under test at 1 GHz 

center frequency and –10 dBm output 

level

[FREQ] [1] {GHz}; [AMPLD] [-] [10] {dBm}

Turn off modulation

[Mod On/Off] and ensure the LED under the key 

is off

Turn on RF output

[RF On/Off] and ensure the LED under the key  

is lit

On the X-Series signal analyzer

Switch to Phase Noise mode

[Mode] {Phase Noise}

Set the signal analyzer with a carrier 

frequency of 1 GHz and an amplitude 

reference level of 0 dBm

[FREQ Channel] {Carrie Freq} [1]{GHz}; [AMPTD 

Y Scale] {Ref Value} [0] {dBm}

View the signal at spectrum domain 

using “Monitor Spectrum”. It is 

always a good idea to use the moni-

tor spectrum measurement to make 

sure your X-Series signal analyzer set 

to the right frequency.
